The present invention relates generally to computing systems, and more particularly to automated discovery of active firewalls and management thereof using ephemeral authentication credentials.
A large-scale cloud-based computer system may include multiple datacenters at various geographic locations to maintain millions of sets of application data for millions of organizations as well as provide millions of sets of application services such as those for customer relationship management, secured data access, online transaction processing, mobile apps, etc., to respective users and/or customers of these organizations. As datacenters grow, evolve and interconnect over time, and as computing resource needs for the organizations evolve over time, networks interconnecting devices continue to grow ever larger and more complex. In current network environments there may be many thousands of interconnected devices, such as client devices, servers, hubs, switches, routers, etc. Some of these devices may be internal to a network and others may be external. The concept of what is a “network” has evolved over time, and does not simply refer to, for example, a company's private network interconnecting the company's data centers, servers, clients, and other hardware/software. As will be discussed further below, a company's internal network may be, for example, a virtual private network defined within networking constructs provided by another entity.
Since the devices may be wired and wirelessly connected and be located anywhere in the world (or outside of it), it will be appreciated the concept of “internal” is generally used to refer to devices that are under some sort of common control or separation from other devices, e.g., devices on an intranet or other collection of private networks. Ingress and egress to an internal network may be managed by firewalls positioned at network edges or perimeters and are configured to monitor data traffic originating external to the network; if the traffic is deemed safe (i.e., trusted), it is allowed to progress through the firewall onto the internal network. Modern firewalls include an operating system (OS) and tools to provide analytics to help identify and stop suspicious data traffic.
Unfortunately a firewall is not a set-it and forget-it type of device. Instead they need to be actively managed and maintained. In a large network environment, many firewalls are used so as to balance access to the internal network, and this necessarily makes managing all of the firewalls a complex task. Typically a firewall may be accessed (with appropriate access credentials) and configured with a desired security configuration. A configuration such as rules and/or IP tables may be used to control the flow of traffic into and/or out of a network (e.g., from a perimeter of the network, such as a private network, and another network, such as the Internet or other public network). The configuration may be configured using a series of commands, and may be utilized by perimeter device (e.g., a hardware firewall device). This may be referred to as “network-based” firewalls. If there are many firewalls, manually updating them is impractical. To address this problem, firewall vendors may provide a management tool to facilitate firewall management. For example, the firewall vendor may provide an Amazon Elastic Compute tool (EC2 tool) that operates as a virtual or physical appliance in the EC2. After manually inputting firewall identification and authentication information into the EC2 tool, the EC2 tool may then operate as a central management point (e.g., a star topology) reaching out to and maintaining active connections with the manually configured firewalls.
The present invention is illustrated by way of example, and not by way of limitation, in the figures of the accompanying drawings and in which like reference numerals refer to similar elements and in which:
The following detailed description discusses multiple exemplary embodiments for more efficiently managing devices, such as firewalls used to protect an organization. It will be appreciated while various alternatives are disclosed, they are approaches that may be pursued, but none are approaches that necessarily must be used. In addition, while issues with solutions may be identified with respect to one or more exemplary approaches described herein, none should be assumed to have been recognized in any prior art on the basis of being identified as a known issue. In this description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, the present invention may be practiced without these specific details. In other instances, well-known structures and devices are not described in exhaustive detail, in order to avoid unnecessarily occluding, obscuring, or obfuscating the present invention.
Examples of systems, apparatus, computer-readable storage media, and methods according to the disclosed implementations are described in this section. These examples are being provided solely to add context and aid in the understanding of the disclosed implementations. It will thus be apparent to one skilled in the art that the disclosed implementations may be practiced without some or all of the specific details provided. In other instances, certain process or method operations also referred to herein as “blocks,” have not been described in detail in order to avoid unnecessarily obscuring the disclosed implementations. Other implementations and applications also are possible, and as such, the following examples should not be taken as definitive or limiting either in scope or setting.
In the following detailed description, references are made to the accompanying drawings, which form a part of the description and in which are shown, by way of illustration, specific implementations. Although these disclosed implementations are described in sufficient detail to enable one skilled in the art to practice the implementations, it is to be understood that these examples are not limiting, such that other implementations may be used and changes may be made to the disclosed implementations without departing from their spirit and scope. For example, the blocks of the methods shown and described herein are not necessarily performed in the order indicated in some other implementations. Additionally, in some other implementations, the disclosed methods may include more or fewer blocks than are described. As another example, some blocks described herein as separate blocks may be combined in some other implementations. Conversely, what may be described herein as a single block may be implemented in multiple blocks in some other implementations. Additionally, the conjunction “or” is intended herein in the inclusive sense where appropriate unless otherwise indicated; that is, the phrase “A, B or C” is intended to include the possibilities of “A,” “B,” “C,” “A and B,” “B and C,” “A and C” and “A, B and C.”
The following is a brief overview of selected features of various embodiments. This overview is not an extensive summary of the invention or claimed embodiments, is not intended to identify particularly significant aspects of disclosed embodiments, and does not delineate any particular scope of the invention. This overview merely presents some concepts that may facilitate, in a condensed and simplified format, understanding more detailed description below and appreciate the breadth of the claimed embodiments.
An EC2 type of device management tool, such as provided to facilitate managing firewalls, requires manual input in the tool of firewall information and credentials, and manual removal for a disabled or broken firewall. If there are many firewalls, and large network environments may have thousands of firewalls protecting access to many devices and/or other network environments (e.g., interconnected private networks), collectively referred to as “internal” destinations, by restricting access from “external” sources (e.g., devices and/or networks such as public networks including the Internet) that are not part of the “internal” network. Any manual operation represents a significant burden. Also, employing a star topology presents a single point of failure risk, and hence a single source security risk affecting all firewalls. If the EC2 tool or its host environment are compromised, and the tool is maintaining active connections to all firewalls, compromising the tool or host environment may lead to all firewalls being maliciously manipulated, data theft, loss, or worse.
Since the devices may be wired and wirelessly connected and be located anywhere in the world (or outside of it), it will be appreciated the concept of “internal” is generally used to refer to devices that are under some sort of common control or separation from other devices, e.g., devices on an intranet or other collection of private networks. Ingress and egress to the internal network may be managed by firewalls that may, for example, be positioned at network edges (or perimeters) and configured to monitor data traffic originating “external” to the network. If the traffic is deemed safe (e.g., trusted), it is allowed to progress through the firewall onto the internal network. An exemplary firewall which may be used to protect internal resources is a firewall provided by Palo Alto Networks, which provides firewalls that include an OS and analytics tools to help identify problematic network traffic and identify potentially dangerous data source and/or destination information, such as by data packet inspection and higher-level protocol inspection, e.g., evaluating Uniform Resource Locator (URL) information.
To ensure firewalls are configured properly they need to be actively managed. To manage a firewall, it needs to be accessed with appropriate access credentials, and then may be configured or reconfigured. But individual access is impractical in environments with more than a few firewalls. To assist with managing firewalls, Palo Alto Networks and other vendor firewalls provide a tool, such as the Palo Alto Networks “Panorama” tool. Other tool examples include Cisco Defense Orchestrator, Cisco Firepower Management Center, ManageEngine Firewall Analyzer, etc. (All referenced marks are the property of their respective owners.) The phrase “management tool” will be used to generally refer various possibilities for presenting the tool, including as a specific purpose device(s) implementing the tool, as a general purpose device(s) implementing the tool, or some combination thereof. Note use of “(s)” herein and the claims that follow, such as in “device(s)” or “credential(s)” is to convey there may be one or more. Regarding specific and general purpose devices see also the
It is expected the reader is familiar tools such as Panorama that operate as a virtual or physical appliance in the cloud, such as the Amazon® Elastic Compute Cloud° (EC2®) (see, e.g.,
In various embodiments disclosed below, an alternate approach to a centralized security management tool such as Panorama, and the like, is a new portable management tool that may be implemented on a device located locally (e.g., logically or physically on an internal environment such as a network), and secure to use (e.g., has operator authentication). And, rather than requiring manual add/delete operations in tools such as Panorama, instead the new tool, as will be discussed further below, will automatically discover active firewalls in an environment based on a criteria that may be used to automatically define a collection of firewalls (or other devices to be managed) and push configuration changes to the collection of discovered firewalls or other devices. The new tool may also operate as a single view on all logs or other data associated with the collection of firewalls, and may be used to find policies, rules, objects, tags (used to define a grouping of devices), groups (one or more devices sharing a characteristic defined with respect to a network tag or other annotation/data associated with a device), etc. relating to the collection of firewalls. In various embodiments, the tool may provide many features and functions, including device (e.g., firewall or other device) Discovery, Add, Modify, Delete, Disable, Enable, Find, List, Load, Log, Reconfigure, Status, View, etc.
In some implementations, the environment 10 is an environment in which an on-demand database service exists. An on-demand database service, such as that which can be implemented using the system 16, is a service that is made available to users outside of the enterprise(s) that own, maintain or provide access to the system 16. As described above, such users generally do not need to be concerned with building or maintaining the system 16. Instead, resources provided by the system 16 may be available for such users' use when the users need services provided by the system 16; that is, on the demand of the users. Some on-demand database services can store information from one or more tenants into tables of a common database image to form a multi-tenant database system (MTS). The term “multi-tenant database system” can refer to those systems in which various elements of hardware and software of a database system may be shared by one or more customers or tenants. For example, a given application server may simultaneously process requests for a great number of customers, and a given database table may store rows of data such as feed items for a potentially much greater number of customers. A database image can include one or more database objects. A relational database management system (RDBMS) or the equivalent can execute storage and retrieval of information against the database object(s).
Application platform 18 can be a framework that allows the applications of system 16 to execute, such as the hardware or software infrastructure of the system 16. In some implementations, the application platform 18 enables the creation, management and execution of one or more applications developed by the provider of the on-demand database service, users accessing the on-demand database service via user systems 12, or third party application developers accessing the on-demand database service via user systems 12.
In some implementations, the system 16 implements a web-based customer relationship management (CRM) system. For example, in some such implementations, the system 16 includes application servers configured to implement and execute CRM software applications as well as provide related data, code, forms, renderable web pages and documents and other information to and from user systems 12 and to store to, and retrieve from, a database system related data, objects, and Web page content. In some MTS implementations, data for multiple tenants may be stored in the same physical database object in tenant database 22. In some such implementations, tenant data is arranged in the storage medium(s) of tenant database 22 so that data of one tenant is kept logically separate from that of other tenants so that one tenant does not have access to another tenant's data, unless such data is expressly shared. The system 16 also implements applications other than, or in addition to, a CRM application. For example, the system 16 can provide tenant access to multiple hosted (standard and custom) applications, including a CRM application. User (or third party developer) applications, which may or may not include CRM, may be supported by the application platform 18. The application platform 18 manages the creation and storage of the applications into one or more database objects and the execution of the applications in one or more virtual machines in the process space of the system 16.
According to some implementations, each system 16 is configured to provide web pages, forms, applications, data and media content to user (client) systems 12 to support the access by user systems 12 as tenants of system 16. As such, system 16 provides security mechanisms to keep each tenant's data separate unless the data is shared. If more than one MTS is used, they may be located in close proximity to one another (for example, in a server farm located in a single building or campus), or they may be distributed at locations remote from one another (for example, one or more servers located in city A and one or more servers located in city B). As used herein, each MTS could include one or more logically or physically connected servers distributed locally or across one or more geographic locations. Additionally, the term “server” is meant to refer to a computing device or system, including processing hardware and process space(s), an associated storage medium such as a memory device or database, and, in some instances, a database application (for example, OODBMS or RDBMS) as is well known in the art. It should also be understood that “server system” and “server” are often used interchangeably herein. Similarly, the database objects described herein can be implemented as part of a single database, a distributed database, a collection of distributed databases, a database with redundant online or offline backups or other redundancies, etc., and can include a distributed database or storage network and associated processing intelligence.
The network 14 can be or include any network or combination of networks of systems or devices that communicate with one another. For example, the network 14 can be or include any one or any combination of a LAN (local area network), WAN (wide area network), telephone network, wireless network, cellular network, point-to-point network, star network, token ring network, hub network, or other appropriate configuration. The network 14 can include a TCP/IP (Transfer Control Protocol and Internet Protocol) network, such as the global internetwork of networks often referred to as the “Internet” (with a capital “I”). The Internet will be used in many of the examples herein. However, it should be understood that the networks that the disclosed implementations can use are not so limited, although TCP/IP is a frequently implemented protocol. It will be appreciated portions of the
The user systems 12 can communicate with system 16 using TCP/IP and, at a higher network level, other common Internet protocols to communicate, such as HTTP, FTP, AFS, WAP, etc. In an example where HTTP is used, each user system 12 can include an HTTP client commonly referred to as a “web browser” or simply a “browser” for sending and receiving HTTP signals to and from an HTTP server of the system 16. Such an HTTP server can be implemented as the sole network interface 20 between the system 16 and the network 14, but other techniques can be used in addition to or instead of these techniques. In some implementations, the network interface 20 between the system 16 and the network 14 includes load sharing functionality, such as round-robin HTTP request distributors to balance loads and distribute incoming HTTP requests evenly over a number of servers. In MTS implementations, each of the servers can have access to the MTS data; however, other alternative configurations may be used instead. It will be appreciated portions of the
The user systems 12 can be implemented as any computing device(s) or other data processing apparatus or systems usable by users to access the database system 16. For example, any of user systems 12 can be a desktop computer, a work station, a laptop computer, a tablet computer, a handheld computing device, a mobile cellular phone (for example, a “smartphone”), or any other Wi-Fi-enabled device, wireless access protocol (WAP)-enabled device, or other computing device capable of interfacing directly or indirectly to the Internet or other network (See also
Each user system 12 also typically includes one or more user input devices, such as a keyboard, a mouse, a trackball, a touch pad, a touch screen, a pen or stylus or the like, for interacting with a graphical user interface (GUI) provided by the browser on a display (for example, a monitor screen, liquid crystal display (LCD), light-emitting diode (LED) display, among other possibilities) of the user system 12 in conjunction with pages, forms, applications and other information provided by the system 16 or other systems or servers. For example, the user interface device can be used to access data and applications hosted by system 16, and to perform searches on stored data, and otherwise allow a user to interact with various GUI pages that may be presented to a user. As discussed above, implementations are suitable for use with the Internet, although other networks can be used instead of or in addition to the Internet, such as an intranet, an extranet, a virtual private network (VPN), a non-TCP/IP based network, any LAN or WAN or the like.
The users of user systems 12 may differ in their respective capacities, and the capacity of a particular user system 12 can be entirely determined by permissions (permission levels) for the current user of such user system. For example, where a salesperson is using a particular user system 12 to interact with the system 16, that user system can have the capacities allotted to the salesperson. However, while an administrator is using that user system 12 to interact with the system 16, that user system can have the capacities allotted to that administrator. Where a hierarchical role model is used, users at one permission level can have access to applications, data, and database information accessible by a lower permission level user, but may not have access to certain applications, database information, and data accessible by a user at a higher permission level. Thus, different users generally will have different capabilities with regard to accessing and modifying application and database information, depending on the users' respective security or permission levels (also referred to as “authorizations”). In one embodiment, the management tool may be disposed in a device 342 (see e.g.,
According to some implementations, each user system 12 and some or all of its components are operator-configurable using applications, such as a browser, including computer code executed using a central processing unit (CPU) such as an Intel Pentium® processor or the like. Similarly, the system 16 (and additional instances of an MTS, where more than one is present) and all of its components can be operator-configurable using application(s) including computer code to run using the processor system 17, which may be implemented to include a CPU, which may include an Intel Pentium® processor or the like, or multiple CPUs.
The system 16 includes tangible computer-readable media having non-transitory instructions stored thereon/in that are executable by or used to program a server or other computing system (or collection of such servers or computing systems) to perform some of the implementation of processes described herein. For example, computer program code 26 can implement instructions for operating and configuring the system 16 to intercommunicate and to process web pages, applications and other data and media content as described herein. In some implementations, the computer code 26 can be downloadable and stored on a hard disk, but the entire program code, or portions thereof, also can be stored in any other volatile or non-volatile memory medium or device as is well known, such as a ROM or RAM, or provided on any media capable of storing program code, such as any type of rotating media including floppy disks, optical discs, digital versatile disks (DVD), compact disks (CD), microdrives, and magneto-optical disks, and magnetic or optical cards, nanosystems (including molecular memory ICs), or any other type of computer-readable medium or device suitable for storing instructions or data. Additionally, the entire program code, or portions thereof, may be transmitted and downloaded from a software source over a transmission medium, for example, over the Internet, or from another server, as is well known, or transmitted over any other existing network connection as is well known (for example, extranet, VPN, LAN, etc.) using any communication medium and protocols (for example, TCP/IP, HTTP, HTTPS, Ethernet, etc.) as are well known. It will also be appreciated that computer code for the disclosed implementations can be realized in any programming language that can be executed on a server or other computing system such as, for example, C, C++, HTML, any other markup language, Java™, JavaScript, ActiveX, any other scripting language, such as VBScript, and many other programming languages as are well known may be used.

In
The process space 28 includes system process space 102, individual tenant process spaces 104 and a tenant management process space 110. The application platform 18 includes an application setup mechanism 38 that supports application developers' creation and management of applications. Such applications and others can be saved as metadata into tenant database 22 by save routines 36 for execution by subscribers as one or more tenant process spaces 104 managed by tenant management process 110, for example. Invocations to such applications can be coded using PL/SOQL 34, which provides a programming language style interface extension to API 32. A detailed description of some PL/SOQL language implementations is discussed in commonly assigned U.S. Pat. No. 7,730,478, titled METHOD AND SYSTEM FOR ALLOWING ACCESS TO DEVELOPED APPLICATIONS VIA A MULTI-TENANT ON-DEMAND DATABASE SERVICE, by Craig Weissman, issued on Jun. 1, 2010, and hereby incorporated by reference in its entirety and for all purposes. Invocations to applications can be detected by one or more system processes, which manage retrieving application metadata 116 for the subscriber making the invocation and executing the metadata as an application in a virtual machine.
The system 16 of
Each application server 100 can be communicably coupled with tenant database 22 and system database 24, for example, having access to tenant data 23 and system data 25, respectively, via a different network connection. For example, one application server 1001 can be coupled via the network 14 (for example, the Internet), another application server 100N-1 can be coupled via a direct network link, and another application server 100N can be coupled by yet a different network connection. Transfer Control Protocol and Internet Protocol (TCP/IP) are examples of typical protocols that can be used for communicating between application servers 100 and the system 16. However, it will be apparent to one skilled in the art that other transport protocols can be used to optimize the system 16 depending on the network interconnections used.
In some implementations, each application server 100 is configured to handle requests for any user associated with any organization that is a tenant of the system 16. Because it can be desirable to be able to add and remove application servers 100 from the server pool at any time and for various reasons, in some implementations there is no server affinity for a user or organization to a specific application server 100. In some such implementations, an interface system implementing a load balancing function (for example, an F5 Big-IP load balancer) is communicably coupled between the application servers 100 and the user systems 12 to distribute requests to the application servers 100. In one implementation, the load balancer uses a least-connections algorithm to route user requests to the application servers 100. Other examples of load balancing algorithms, such as round robin and observed-response-time, also can be used. For example, in some instances, three consecutive requests from the same user could hit three different application servers 100, and three requests from different users could hit the same application server 100. In this manner, by way of example, system 16 can be a multi-tenant system in which system 16 handles storage of, and access to, different objects, data and applications across disparate users and organizations.
In one example storage use case, one tenant can be a company that employs a sales force where each salesperson uses system 16 to manage aspects of their sales. A user can maintain contact data, leads data, customer follow-up data, performance data, goals and progress data, etc., all applicable to that user's personal sales process (for example, in tenant database 22). In an example of a MTS arrangement, because all of the data and the applications to access, view, modify, report, transmit, calculate, etc., can be maintained and accessed by a user system 12 having little more than network access, the user can manage his or her sales efforts and cycles from any of many different user systems. For example, when a salesperson is visiting a customer and the customer has Internet access in their lobby, the salesperson can obtain critical updates regarding that customer while waiting for the customer to arrive in the lobby.
While each user's data can be stored separately from other users' data regardless of the employers of each user, some data can be organization-wide data shared or accessible by several users or all of the users for a given organization that is a tenant. Thus, there can be some data structures managed by system 16 that are allocated at the tenant level while other data structures can be managed at the user level. Because an MTS can support multiple tenants including possible competitors, the MTS can have security protocols that keep data, applications, and application use separate. Also, because many tenants may opt for access to an MTS rather than maintain their own system, redundancy, up-time, and backup are additional functions that can be implemented in the MTS. In addition to user-specific data and tenant-specific data, the system 16 also can maintain system level data usable by multiple tenants or other data. Such system level data can include industry reports, news, postings, and the like that are sharable among tenants.
In some implementations, the user systems 12 (which also can be client systems) communicate with the application servers 100 to request and update system-level and tenant-level data from the system 16. Such requests and updates can involve sending one or more queries to tenant database 22 or system database 24. The system 16 (for example, an application server 100 in the system 16) can automatically generate one or more SQL statements (for example, one or more SQL queries) designed to access the desired information. System database 24 can generate query plans to access the requested data from the database. The term “query plan” generally refers to one or more operations used to access information in a database system.
Each database can generally be viewed as a collection of objects, such as a set of logical tables, containing data fitted into predefined or customizable categories. A “table” is one representation of a data object, and may be used herein to simplify the conceptual description of objects and custom objects according to some implementations. It should be understood that “table” and “object” may be used interchangeably herein. Each table generally contains one or more data categories logically arranged as columns or fields in a viewable schema. Each row or element of a table can contain an instance of data for each category defined by the fields. For example, a CRM database can include a table that describes a customer with fields for basic contact information such as name, address, phone number, fax number, etc. Another table can describe a purchase order, including fields for information such as customer, product, sale price, date, etc. In some MTS implementations, standard entity tables can be provided for use by all tenants. For CRM database applications, such standard entities can include tables for case, account, contact, lead, and opportunity data objects, each containing pre-defined fields. As used herein, the term “entity” also may be used interchangeably with “object” and “table.”
In some MTS implementations, tenants are allowed to create and store custom objects, or may be allowed to customize standard entities or objects, for example by creating custom fields for standard objects, including custom index fields. Commonly assigned U.S. Pat. No. 7,779,039, titled CUSTOM ENTITIES AND FIELDS IN A MULTI-TENANT DATABASE SYSTEM, by Weissman et al., issued on Aug. 17, 2010, and hereby incorporated by reference in its entirety and for all purposes, teaches systems and methods for creating custom objects as well as customizing standard objects in a multi-tenant database system. In some implementations, for example, all custom entity data rows are stored in a single multi-tenant physical table, which may contain multiple logical tables per organization. It is transparent to customers that their multiple “tables” are in fact stored in one large table or that their data may be stored in the same table as the data of other customers.
Examples of cloud service providers include, by way of example only and not as limitations inferred from perceived differences in cloud services and/or infrastructure, include Amazon Virtual Private Cloud (Amazon VPC), Amazon Elastic Compute Cloud (EC2), Microsoft Azure (e.g., Hybrid cloud), Google Cloud, Alibaba Cloud, IBM's cloud services, Oracle cloud services, etc. It will be appreciated these and other cloud services and cloud infrastructure vendors provide on-demand and configurable shared computing resources allocated from one or more public and/or private cloud environments, and may provide virtual private environments isolated from other environments/customers having their own associated resources. Various hardware and/or software techniques may be used to establish private environments, such as by allocating private address spaces, e.g., Internet Protocol (IP) subnets, providing private virtual communication interfaces, e.g., virtual Local Area Networks (VLANs), virtual private networks (VPNs) to securely control access to virtual private environments. See, e.g.,
In some embodiments, it is assumed private networks, virtual private environments, or the like, use Palo Alto Networks (PAN) Firewalls (FWs) or equivalent type devices as security devices to protecting access to restricted resources. In some embodiments, the Amazon Web Services (AWS) platform may be used to implement a private environment shielded by the PAN firewalls where a management tool may be used to access and/or configure the firewalls. However, unlike the Panorama or equivalent type of centralized (hub and spoke configuration) management tool that, if compromised, leaves all devices at risk, instead a local management tool may be used. The term “local” refers to using a tool considered located on an internal network, where “internal” may be considered as referring to destinations and/or resources on a private network and/or a private environment.
In the illustrated embodiment, one operation is to obtain 202 a copy of the management tool. It will be appreciated aspects of disclosed embodiments may be performed by a dedicated computing device, e.g., a device operating under control of an application specific integrated circuit (ASIC), programmable gate array (PGA), field PGA (FPGA), or other fixed and/or programmable circuitry, or a general purpose computing device (e.g., a laptop). The management tool therefore may be firmware or other information required to configure a dedicated computing device, or it may be presented as software that may be executed on the general purpose computing device, or it could be a combination of both, e.g., a device having some specific device functionality that may also process software. See also the
Once the software has been obtained, a cloud service may be accessed 204. In the illustrated embodiment, for security, a credential(s) is provided 206 to authenticate use of the management tool (and/or the device implementing management tool) with the cloud service. It will be appreciated any manner of cryptographic environment may be used to authenticate, such as sharing a known pre-shared key and/or certificate, entering a username and password, public key cryptography (PKC), International Telecommunications Union (ITU) X.509, public key infrastructure (PKI), etc. Assuming authentication is successful, a device identifier may be provided 208. In one embodiment, the device(s) to be managed are assumed to be grouped according to some characteristic. For example, one could decide to manage all devices sharing the same network tag, or based on a particular region/portion of a network, and thus use a network address or network address mask to identify specific devices. In one embodiment the provided 208 identifier is the IP address of a device.
With the provided identifier, the device's environment may be determined 210. For example, if we assume identifiers are IPv4 network addresses, if the provided 208 identifier was 10.10.10.10, we can determine the device environment to be the 10.0.0.0/24 address space. It will be appreciated determined environment will vary based on the type of identifier that is provided. In this example, we can assume a subsequent operation is to search 212 for active devices (to be managed) in the determined 210 environment. Typically, a management tool (such as the “Panorama” and similar such tools discussed above) requires devices to be managed be manually added and removed from the software. This can be a tedious and error prone task if there are many devices to be managed. In contrast to that type of system, in this illustrated embodiment, rather than rely on pre-existing device lists, instead the search 212 performs a new identification of all devices that are currently active. Thus, if a device is missing, broken/non-responsive, or intentionally disabled, the search will skip over those devices. There is no need in the illustrated embodiments to manually add or remove devices.
Once the active devices are identified, then management options may be displayed 214. It will be appreciated the term “display” corresponds to whatever format of output is needed to present operation choices to the management tool. For example if an Artificial Intelligence (AI) Engine (see, e.g.,
For other operations requiring authorization, such as a reconfiguration, there may be a prompt 218 for a device credential(s) to access restricted operations and/or restricted device resources. As with the display 214 operation discussed above, the prompt may be an operation that varies according to the nature of the device operating the management tool. What constitutes valid Input/Output (I/O) may vary. And as with providing 206 cloud credentials, any of the known cryptographic operations discussed above, as well as other known authentication schemes may be used to authenticate permission to perform the selected 216 management option. In one embodiment, it is assumed devices require a username and password in response to the prompt for a device credential(s). For expository convenience, it is assumed devices to be managed may share authentication credential(s) to access the devices. In another embodiment there may be different credentials for different devices and that the prompt for device credential(s) may be repeated (not illustrated) for other devices if and as needed. If 220 the supplied credential(s) is not valid, then processing may loop back to prompting for the credential(s). It will be appreciated the illustrated operations are an over-simplification of program operation and other processes and/or checks and/or other operations may be performed instead of a simple loop-back.
If 220 the credential(s) is valid, then in one embodiment the management tool may access the device though one or more calls 222 to an Application Programming Interface (API) associated with the device. The API may be a public and/or private interface providing access to functions and/or features of devices. For example, the API may be used to Modify a device to reconfigure it to perform differently. After authenticating with the device to show the management tool is authorized to interact with the device, one or more API calls may be made to generate 224 an ephemeral credential(s). Ephemeral credentials are intended to be stored in a volatile storage of some sort, such as within device memory, where the memory may be released (e.g., cleared, flushed, securely erased, etc.) after need for them ends. For example, they can be stored in device memory and released after completion of managing devices associated with the credential(s), or when the management tool is exited or shutdown.
As discussed the management tool may support an arbitrary set of operations that may be exposed by an API to facilitate managing the device. It will be appreciated the API may be standardized as well defined to be extensible so in future new features may be implemented by the devices and incorporated into the API. The API may include functions such as version information and function list to provide information about what the API is capable of performing. And it will be appreciated an API may provide one function that utilizes one or more functions provided by a device, or the converse may occur, where multiple API calls access one device feature or function. It will be further understood an API may also aggregate multiple devices into a logical device, and the logical device may have features and capability not provided by any of the individual devices in the aggregation. For example, in a group of two devices, a first one may communicate using one protocol incompatible with the management tool, and a second one may support communication with the management tool, and the API for the second device may support aggregating and communication on behalf of the first devices. In such fashion the lifespan of older devices may be extended, at least temporarily, until they may be upgrade or replaced with a newer device.
In the illustrated embodiment, the ephemeral credential(s) may be received directly from the device to be managed, however in another embodiment the credential(s) may be indirectly retrieved from another source if authorized by the device, e.g., the device may authorize retrieving credentials from the cloud service on behalf of the device. Device credential(s) or other identification information is not saved in the management tool, thus alleviating risk inherent to Panorama and other such centralized management tools being compromised and giving access to all managed devices. By accessing 204 the cloud service with one credential(s) and accessing 218 the device with another credential(s), we get a safer multi-stage authentication process than provided by conventional management tools.
The selected 216 management option may then be processed. For example, if 226 the choice was to reconfigure the device, a new configuration may be pushed 228 to the device(s). Not illustrated are operations relating to determining the new configuration to be pushed to the device. A new configuration may be created in a variety of ways, including manually entering device configuration changes in the tool, uploading a configuration from an external source, e.g., an internal network location or retrieving from a server, retrieving from an internal memory that has received and stored the new configuration, applying a “smart” rule, e.g., an intelligent or Al (see, e.g.,
If 230 management of the device(s) is done/complete, then the ephemeral credential(s) may be cleared 232. If 230 not done, then for example, processing may loop back to performing displaying 214 and selecting 216 a different management option to perform. In one embodiment, the displaying 214 management options may dynamically change what may be performed if, for example, a previous operation makes different choices available or unavailable due to the previous choices. It will be also be appreciated illustrated embodiments simplify operations that may be performed and related operational flow. And, if 226 the selected management option was not reconfiguration, then other operation(s) may be performed 234 (including providing 208 a new identifier and starting a new search 212 for different devices to manage), and a test made to determine if 230 management is done.
It is understood the VPC may be implemented by the cloud service on a private network 338 and/or public network 340. The underlying network does not matter so long as a private network environment, sometimes called an “intercloud”, is define such that it includes machines within a perimeter, where the perimeter separates items internal to a particular private environment from items external to that private environment. For example, each VPC 306-312 has its own associated private environment, perimeter and machines (including firewalls 314-316) inside the private environment. It will be appreciated some or all firewalls 314-336 may be considered to be a gateway or pathway through the perimeter, where the firewalls have interfaces, communication ports, or the like facing both inward toward machines internal to a private environment, as well as facing external, such as to receive connections from the Internet 340. One skilled in the art understands how various VPC environments may be defined, such as to define private environments with respect to networks 338 that may be accessed by way of another network, such as the Internet 340. Although not illustrated as such, there could be multiple network clouds 338 each surrounding the illustrated VPCs 306-312 to which all may have a connection to the Internet 340 or other network to be used to access the various private environments associated with network(s) 338.
As illustrated a mobile computing device 342, such as a laptop computer, dedicated computing device, or other machine operates the management tool and accesses one of the cloud accounts 302-304, for example, the first cloud account 302 as illustrated by pathway 344. It will be appreciated the mobile device may be configured like the
It will be appreciated the mobile device 342 does not have to be physically local to the environment, e.g., directly attached to the network(s) 338 in which devices to be managed are physically and/or virtually located. In one embodiment, the mobile device 342 is located on a public network, such as the Internet 340, and the mobile device uses a Virtual Private Network (VPN) or other secure communication technology to create a communication pathway 348 with a cloud account, e.g., the illustrated Nth cloud account 304, to gain access to the VPC and access and/or manage firewalls, e.g., firewalls B1-Bn 332-336 in the Nth VPC 312 associated with the cloud account 304. By way of the secure communication pathway to the VPC, the firewall may be reached, such as to use Application Programming Interfaces (APIs) that expose features and/or functionality of a firewall, while also allowing the firewall to remain protected from general access from a public network. Communication with the cloud account, VPC and/or firewall(s) may be over wired and/or wireless pathways, for example, pathways 348, 350 or using other pathways (not illustrated); pathways 348, 350 may be the same pathway, or separate pathways.
Thus, once a management tool has obtained an appropriate access key, or token or the like from a cloud account 302, 304, the management tool may use a characteristic of one of devices to be managed to search a cloud account for other visible devices, e.g., active/enabled not inactive/disabled/disconnected, associated with the cloud account and sharing the search characteristic. As discussed above, the characteristic may be the IP address of one firewall that may be used to identify a private environment (e.g., one or more of the VPCs 306-312). Note depending on the search, the defined environment need not be restricted to a single VPC. The identified firewalls in the private environment may be accessed after clearing subsequent multi-level authentication, e.g., prompting for a username/password, before proceeding with granting access to manage the one or more identified firewalls.
It will be appreciated the characteristic may be any criteria/discernable data about a device, such as a tag associated with the device, a certain manufacturer, a specific firmware version, a particular amount of memory, a specific network location, a particular role (e.g., operating as a firewall, gateway, router, server, client, etc.), providing a particular service (e.g., web server, proxy, database, sales, contact management, etc.), or the like. A private environment may then be defined with respect to devices that satisfy the search criteria. It will be appreciated in addition to multi-level authentication noted above, if the management tool is disposed within a portable device such as a laptop computer, the user of the mobile device may be tested for appropriate characteristics before being allowed to manage devices in the private environment. For example, a mobile device user may be required to belong to a particular Active Directory (AD) group, in addition to satisfying multi-level authentication, e.g., knowing a username/password or other requested security information. If the username/password is a second level authentication, then requiring certain AD credential(s) is a tertiary level.
Although not illustrated, it will be appreciated the devices within the collection of devices may be managed individually or collectively, and either sequentially and/or in parallel. Thus for one or more of the devices, an authentication credential(s) may be provided 408 to the one or more device to manage. It will be appreciated for security, authentication tokens, keys, credentials, usernames, passwords, etc. may be required to be provided to the cloud service, and devices to be managed, before privileged/restricted information may be obtained, created or updated. Communication with devices does not need to be direct, other devices and/or entities may be involved in communication with a device to be managed, e.g., there may be intermediaries facilitating communication with a device where the intermediary itself requires authentication before facilitating. Security authentication may be different for the cloud service than what is used to access manageable devices. Manageable devices may share authentication credentials (such as a common username/password), or use different authentication.
In the illustrated embodiment, responsive to an authentication 408 to a device to be managed, an access authentication credential(s), e.g., an access key or token, may be received from the device and the access credential is ephemerally cached 410. For example, provided 408 authentication may be a username/password to log into a device to be managed, and responsive to the login an access key may be provided which may be used to manage that device going forward. The access key would be provided along with subsequent attempts to manage the device so the device knows the communication is authorized. In one embodiment, the device creates temporary access keys that have a limited lifespan. The terms “ephemeral”, “ephemerally,” and the like are used herein to denote access keys/token/etc. are not retained by a management tool or device implementing the management tool. Thus, for example, in one embodiment, after an initial authentication with a device, the device may return a token (or other data or identifier) that may be used by a tool to manage the device. If a management tool uses an API to access the device, in one embodiment some or all of the API calls may include the token (or other data) to validate API calls to the managed device. This results in the tool not having to remain logged in (or equivalent) to the device and when management is concluded, deleting the token prevents subsequent access to the device without re-authenticating 408.
Assuming a desire to reconfigure or otherwise change the configuration of a device, a new or updated configuration may be obtained or created anew with the management tool, and applied 412 to the device(s) in the collection of devices. As noted above, the management of devices may be individually performed, e.g., sequentially, or wholly or partially performed in parallel. Once management is complete, e.g., the tool is exited or otherwise shut down or the device running the management tool is shut down, put to sleep, left idle, etc., the ephemerally cached 410 credentials are flushed 414 to prevent risk of security compromise.
A first credential may be provided 502 to a cloud service, such as the Amazon AWS service providing EC2 virtual private cloud (EC2) services to define a private environment containing resources having access thereto protected by firewalls. It will be appreciated the credential may vary but for the AWS environment, the credential may be one or more AWS key for an AWS account. Assuming a management tool, which may be a specific purpose device or general purpose device programmed to provide the tool, is seeking to manage firewalls, the first credential authenticates the management tool to the cloud service. Once authenticated the management tool may interact with the cloud service. In the illustrated embodiment, an Application Programming Interface (API) is used to interact with the cloud service, including to provide the credential, and to perform operations such as to discover all firewalls associated with the cloud service. As illustrated, we can use the API to send 504 the cloud service the network address of a known firewall, or a tag associated with the firewall, and use that address or tag to search the cloud service to discover 506 all known firewalls, for example, on the same network as the network address of the known firewall, or sharing the same tag.
It will be appreciated the cloud service may know of more firewalls than are actually active/available for management. For example, some firewalls may be broken, disconnected, powered off, logically off (e.g., set to ignore network contact), or otherwise unavailable or unreachable. Therefore while we may discover 506 all known firewalls related to the network address of the known firewall, we next automatically search 508 the discovered firewalls to identify 510 all active firewalls, e.g., firewalls that are available to be managed. The management tool may then provide options available to manage discovered active firewalls, to which we can assume for the purposes of this discussion a user chooses 512 to reconfigure one or more firewall. Assuming the firewalls all use the same access credential (e.g., a login or other access credential), in one embodiment, the user of the management tool may provide 514 the management tool with a second credential to authenticate with the firewall. The second credential may be ephemerally cached 516 and used to connect 518 to each of the active firewall to be reconfigured.
After the management tool successfully authenticates with a firewall, the management tool may receive 520 a temporary access key, token or other data from the firewall to be used in API calls made to the firewall to manage the firewall. In one embodiment multiple firewalls may be configured to at least temporarily share the same temporary access key provided responsive to the second credential, e.g., so that API calls to access any of the available firewalls may provide the same temporary access key. In another embodiment, each firewall provides a different temporary access key responsive to the providing 514 the second credential. Thus, the management tool is then authorized to apply 522 a new configuration to the firewalls. Once management of the active firewalls is completed, the management tool may be exited, e.g., logged out, shut down, or the like, resulting in any cached passwords, keys, credentials, etc. are flushed 524 out of memory.
Specific purpose devices include by way of example only and not intended to be a limitation, desktop computer systems, portable computer systems, handheld devices, networking devices, telephones, tablets, transportation devices, or any other device that incorporates hard-wired and/or program logic to implement disclosed embodiments. General purpose devices, include by way of example only and not intended to be a limitation, a laptop (see, e.g.,
The computer system 602 also includes a memory 612, e.g., a main memory, such as a random access memory (RAM) or other dynamic storage device, coupled to the bus 604 for storing information and instructions to be executed by the processor(s) 606. The main memory may also be used for storing temporary variables or other intermediate information during execution of instructions to be executed by the processor(s). Such instructions, when stored in non-transitory storage media accessible to the processor(s), render the computer system into a special-purpose machine that is device-specific to perform the operations specified in the instructions. The computer system may further include a read only memory (ROM) 614 or other static or non-volatile storage device coupled to the bus 604 for storing information or instructions for the processor(s). A storage device or devices 616, such as a magnetic disk, optical disk, or other storage media may be provided and coupled to the bus for storing information and instructions.
The computer system 602 may be coupled via the bus 604 to one or more output device(s), e.g., display(s) 618, such as a liquid crystal display (LCD), for displaying information to a computer user. A display may also include devices, such as Braille output devices, or other devices intended to facilitate presenting information to users that may benefit from sensory accommodation, such tactical and/or altered visual output for sight-impaired users. There may also be input devices 620, including alphanumeric and/or other keys, coupled to the bus for communicating information and command selections to the processor(s) 606. There may be other input devices 622, such as a mouse/tablet/trackball/cursor direction keys/Braille device, or other sensors including biometric devices to translate biometric information into input, for communicating direction information and command selections to the processor(s), and which may control, for example, cursor movement on the display(s). There may also be Virtual Reality Input/Output (I/O) 624 devices that may be used in addition to or in lieu of the other devices 618-622. It will be appreciated Virtual Reality may operate both as an information display of operation of the computer system, and also provide 2D and 3D input mechanisms, e.g., through movement of wands or other devices the virtual reality system monitors, as well as by visual monitoring and analysis of use movement, such as gesturing. The input and output devices 618-624 may communicate with the computer system over one or more communication pathways 626 that may interconnect these devices with the computer system. The computer system may be remotely controlled and not require direct user access.
The computer system 602 may implement the techniques described herein using device-specific hard-wired logic, one or more ASICs or FPGAs, firmware and/or program logic which in combination with the computer system causes or programs the computer system to be a special-purpose machine. As circuit technology continues to advance it is contemplated that disclosed embodiments may be presented with advancing technology. For example, quantum-state readout and measurement circuits for qubits, used in quantum computation devices, may be used to encode the processing and/or data storage aspects of disclosed embodiments. According to one embodiment, the techniques herein are performed by the computer system in response to the processor(s) 606 executing one or more sequences of one or more instructions contained in the memory 612. Such instructions may be read into the memory from another storage medium, such as from the storage device(s) 616. Execution of the sequences of instructions contained in the memory causes the processor(s) to perform the process steps described herein. In alternative embodiments, hard-wired circuitry may be used in place of or in combination with software instructions.
Storage media refers to any at least partially non-transitory media that may store data and/or instructions that cause a machine to operation in a specific fashion. Non-volatile media includes, for example, solid state disks (SSDs), optical or magnetic disks, etc. and may be used at the storage device(s) 616. Volatile media includes dynamic memory, such as the memory 612. There are many known volatile and/or non-volatile media memory and media formats that may be used to provide temporary or permanent storage. Storage media may be used in conjunction with transmission media. Transmission media participates in transferring information between storage media. For example, transmission media includes wireless and wired mediums, including the bus 604, modulated signals, acoustic waves, or light waves, such as those generated during radio-wave and infra-red data communications. It will be appreciated data may be optically encoded (e.g., represented as light packets), to encode instructions, data, and/or operational state of the computing system.
Various forms of media may be involved in carrying one or more sequences of one or more instructions to the processor(s) 606 for execution. For example, the instructions may initially be carried on storage of a remote computer. Assuming a similar configuration as the computer system 602, the remote computer can load the instructions into its memory and send the instructions over a communication pathway, which may be any form of wired or wireless communication medium. A corresponding receiving device local to the computer system may receive the data and convert the received information for placement on the bus 604. The bus may then carry the data to the memory 612, from which the processor(s) retrieves and executes the instructions. The instructions may be stored on the storage device(s) 616 before or after execution by the processor(s).
The computer system 602 includes a communication interface(s) 628 coupled to the bus 604. The communication interface(s) provides a two-way data communication coupling to a network 630 that is connected to a local network(s) 632. The communication interface(s) may include devices to communicate over a network such as by way of a local area network (LAN) or other network to provide a data communication connection for the computer system. Wireless links may be utilized. The communication interface(s) sends and receives signals in a format appropriate to the communication medium (e.g., electrical, electromagnetic, optical, etc.) that carry digital data streams representing various types of information. The communication interface(s) 628 allow a computer system to send and/or receive information through one or more network(s) to other data devices. For example, there may be a network link through the local network(s) to a host computer 634. There may be a link 636 that interconnects the local network(s) with the Internet 638, through which the computer system may communicate with another machine, such as one or more remote server(s) 640 which may send or receive requests to process data, retrieve and/or store information, etc.
In addition, various embodiments may employ Artificial Intelligence (AI) Engines (or “machine intelligence”) to assist with operating, e.g., the management tool, devices being managed by the management tool, or other devices/machines as desired. It will be appreciated there are many different AI Engines that may be employed, such as neural networks (feedforward, recurrent, backpropagation, deep learning, etc.), expert systems, and many other analytical systems. It will be appreciated an AI Engine 640 may be incorporated into the computer system 602. However, since a robust AI Engine may require robust resources unavailable to certain computers, and AI Engine 642 may be available over a local network(s) 632 and/or an AI Engine 644 may be available as a remote resource accessible over, for example, the Internet 638. It will be appreciated one or more of the AI Engines 640-644 may cooperatively operate to analyze problems and suggest answers.
