Cloud Security Management

FIELD OF THE INVENTION

The present technology pertains to communications networks, and more specifically to security in cloud computing environments.

BACKGROUND ART

The approaches described in this section could be pursued but are not necessarily approaches that have previously been conceived or pursued. Therefore, unless otherwise indicated, it should not be assumed that any of the approaches described in this section qualify as prior art merely by virtue of their inclusion in this section.

Due to the extensive use of computer networks by enterprises, there has been a dramatic rise in network attacks, a proliferation of computer viruses, and a constant distribution of other types of malicious content that attempts to attack, infect, or otherwise infiltrate the computer networks. Attackers breach internal networks and public clouds to steal critical data. For example, attackers target low-profile assets to enter the internal network. Inside the internal network and public clouds, and behind the hardware firewall, attackers move laterally across the internal network, exploiting East-West traffic flows, to critical enterprise assets. Once there, attackers siphon off valuable company and customer data.

FIG. 1 shows cloud computing environment 100 including workloads 110_1,1-110_X,Y, according to some embodiments. Cloud computing environment 110 provides on-demand availability of computer system resources, such as data storage and computing power. Cloud computing environment 110 can physically reside in one or more data centers and/or be physically distributed over multiple locations. Cloud computing environment 110 can be hosted by more than one cloud service, such as those provided by Amazon, Microsoft, and Google. Cloud computing environment 110 can be limited to a single organization (referred to as an enterprise cloud), available to many organizations (referred to as a public cloud,) or a combination of both (referred to as a hybrid cloud). Examples of public clouds include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).

Each of workloads 110_1,1-110_X,Ycan be a unit of computing resource, such as a physical computing system (also referred to as a bare metal server), virtual machine, container, pod, and combinations thereof. A physical computing system is computer hardware and not a virtual computing system, such as a virtual machine and container. In addition to running operating systems and applications, physical computing systems can be the hardware that virtual computing systems run on.

A virtual machine provides a substitute for a physical computing system, including functionality to execute entire operating systems. Virtual machines are created and run by a hypervisor or virtual machine monitor (VMM). A hypervisor is computer software or firmware which can run on workloads 110_1,1-110_X,Y. A hypervisor uses native execution to share and manage hardware, allowing for multiple environments which are isolated from one another, yet exist on the same physical computing system.

Containers are an operating system-level virtualization method for deploying and running distributed applications without launching an entire virtual machine for each application. Containers can look like physical computing systems from the point of view of programs running in them. Generally, a computer program running on an operating system can see all resources (e.g., connected devices, files and folders, network shares, CPU power, etc.) of that physical computing system. However, programs running inside a container can only see the container's contents and devices assigned to the container. A pod is a group of containers with shared storage and/or network resources, and a shared specification for how to run the containers.

A container is an instance of an image. An image can be a file, comprised of multiple layers, with information to create a complete and executable version of an application. Containers can be arranged, coordinated, and managed—including means of discovery and communications between containers—by container orchestration (e.g., Docker Swarm®, Kubernetes®, Amazon EC2 Container Service (ECS), Diego, Red Hat OpenShift, and Apache® Mesos™). In contrast to hypervisor-based virtualization, containers may be an abstraction performed at the operating system (OS) level, whereas virtual machines are an abstraction of physical hardware.

Typically, workloads 110_1,1-110_X,Yof cloud computing environment 100 individually and/or collectively run applications and/or services. Applications and/or services are programs designed to carry out operations for a specific purpose. By way of non-limiting example, applications can be a database (e.g., Microsoft® SQL Server®, MongoDB, Hadoop Distributed File System (HDFS), etc.), email server (e.g., Sendmail®, Postfix, qmail, Microsoft® Exchange Server, etc.), message queue (e.g., Apache® Qpid™, RabbitMQ®, etc.), web server (e.g., Apache® HTTP Server™, Microsoft® Internet Information Services (IIS), Nginx, etc.), Session Initiation Protocol (SIP) server (e.g., Kamailio® SIP Server, Avaya® Aura® Application Server 5300, etc.), other media server (e.g., video and/or audio streaming, live broadcast, etc.), file server (e.g., Linux server, Microsoft® Windows Server®, etc.), service-oriented architecture (SOA) and/or microservices process, object-based storage (e.g., Lustre®, EMC® Centera®, Scality® RING®, etc.), directory service (e.g., Microsoft® ActiveDirectory®, Domain Name System (DNS) hosting service, etc.), and the like.

Physical computing systems and cloud computing environments are described further in relation to FIG. 6.

FIG. 2 shows system 200 for cloud security management, according to some embodiments. System 200 includes controller 210. Controller 210 can receive streaming telemetry 275 from network logs 270, events 285 from cloud control plane 280, and inventory 295 from configuration management database (CMDB) 290.

Network logs 270 can be data sources such as flow logs from cloud services 260₁-260_Z(e.g., Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP)), vArmour DSS Distributed Security System, Software Defined Networking (SDN) (e.g., VMware NSX and Cisco Application Centric Infrastructure (ACI)), monitoring agents (e.g., Tanium Asset and Falco), and the like. Generally, streaming telemetry 275 can be low-level data about relationships between applications. Streaming telemetry 275 can include 5-tuple, layer 7 (application layer) process information, management plane logs, and the like. 5-tuple refers to a set of five different values that comprise a Transmission Control Protocol/Internet Protocol (TCP/IP) connection: a source IP address/port number, destination IP address/port number and the protocol in use. Streaming telemetry can alternatively or additionally include a volume of data (i.e., how much data is or how many data packets are) exchanged between workloads (e.g., workloads 110_1,1-110_X,Yin FIG. 1) in a network, (dates and) times at which communications (e.g., data packets) are exchanged between workloads, and the like.

Cloud control plane 280 establishes and controls the network and computing resources within a cloud computing environment (e.g., cloud computing environment 100 in FIG. 1). Cloud control plane 280 can include interfaces for managing assets (e.g., launching virtual machines and/or containers, configuring the network, etc.) in a cloud computing environment. For example, cloud control plane 280 can include one or more instances of container orchestration, such as Docker Swarm®, Kubernetes®, Amazon EC2 Container Service (ECS), Diego, and Apache® Mesos™. By way of further non-limiting example, cloud control plane 280 can include VMware vSphere, application programming interfaces (APIs) provided by cloud services 260₁-260_Z, and the like.

Events 285 can include information about a container (and/or a pod) being created, having a state change, having an error, and the like. For example, when a container is created, information about the workload such as a service name, image deployed, and the like can be received in events 285. By way of further example, additional information from an image registry corresponding to the deployed image can be gathered by controller 210.

Configuration management database (CMDB) 290 can be a database of information about the hardware and software components (also known as assets) used in a cloud computing environment (e.g., cloud computing environment 100 in FIG. 1) and relationships between those components and business functions. CMDB 290 can include information about upstream sources or dependencies of components, and the downstream targets of components. For example, inventory 295 can be used to associate an application name and other information (e.g., regulatory requirements, business unit ownership, business criticality, and the like) with the workload (e.g., workloads 110_1,1-110_X,Yin FIG. 1) it is running on.

Streaming telemetry 275, events 285, and inventory 295 can be ingested by graph 220. Graph 220 normalizes information received in streaming telemetry 275, events 285, and inventory 295 into a standard data format and/or model, graph database 225. Graph database 225 uses a graph data model comprised of nodes (also referred to as vertices), which is an entity such as a workload (e.g., of workloads 110_1,1-110_X,Yin FIG. 1), and edges, which represent the relationship between two nodes. Edges can be referred to as relationships. An edge can have a start node, end node, type, and direction, and an edge can describe parent-child relationships, actions, ownership, and the like. In contrast to relational databases, relationships are (most) important in graph database 225. In other words, connected data is equally (or more) important than individual data points.

Conventionally, security management systems stored raw logs of each and every individual communication between workloads. The amount of data scaled linearly and consumed massive amounts of storage. In contrast, streaming telemetry 275, events 285, and inventory 295, graph 220 (FIG. 2) can be used by graph 220 to create and update graph (database) 300. The individual communications are not stored. In this way, graph database 225 is advantageously scalable. For example, graph database 225 for a large cloud computing environments of 30,000-50,000 workloads can be stored in memory of a workload (e.g., of workloads 110_1,1-110_X,Yin FIG. 1).

FIG. 3 depicts (simplified) graph (database) 300 of a cloud computing environment, according to various embodiments. Graph 300 is a simplified example, purely for illustrative purposes, of a graph in graph database 225 (FIG. 2). Graph 300 can include three workloads (e.g., of workloads 110_1,1-110_X,Yin FIG. 1): node 310, node 330, and node 350. As shown in FIG. 3, edge (relationship) 320 is between nodes 310 and 330 have; edge (relationship) 340 is between nodes 330 and 350; edge (relationship) 360 is between nodes 350 and 310.

Using streaming telemetry 275, events 285, and inventory 295, graph 220 (FIG. 2) can determine information 335 about node 330. By way of non-limiting example, information 335 can include an application name, application function, business organization (e.g., division within a company), realm (e.g., production system, development system, and the like), (geographic) location/zone, and other metadata. Moreover, using layer 7 information (when available), the name of the database can be determined.

Referring back to FIG. 2, graph 220 can employ various techniques to manage entropy. In a cloud computing environment (e.g., cloud computing environment 100 in FIG. 1), entropy is change to the workloads (e.g., created and removed), communications among workloads (e.g., which workloads communicate with other workloads), applications and services provided in the network, and the like. Typically in a (closed) enterprise cloud, entropy is low. For example, after monitoring an enterprise cloud for one month, another month of monitoring will reveal little that is new.

On the other hand, a web server connected to the Internet will have high entropy, because the number of relationships (connections) to clients on the Internet (nodes) is huge and continues to grow. To protect the size of graph database 225, graph 220 can recognize when there is high entropy and summarize the nodes. For example, the vast (and growing) number of clients on the Internet is represented by a single “Internet” object with one edge to the web server node.

According to some embodiments, a new relationship can be created around a particular node in graph database 225, as streaming telemetry 275, events 285, and inventory 295 are processed by graph 220. Graph 220 (FIG. 2) can further re-analyze the edges (relationships) connected to the particular node, to classify what the particular node is. For example, if the node accepts database client connections from systems that are known to be application servers, then graph 220 may classify the node as a database management system (i.e., a certain group). Classification criteria can include heuristic rules. Graph 220 can use machine learning algorithms and measure how close a particular node is to satisfying conditions for membership in a group. Classification is described further in U.S. Pat. No. 10,264,025 issued Apr. 16, 2019, titled “Security Policy Generation for Virtualization, Bare-Metal Server, and Cloud Computing Environments,” which is hereby incorporated by reference for disclosure of classification.

Visualize 230 can visually present information from graph database 225 to users according to various criteria, such as by application, application type, organization, and the like. FIGS. 4A and 4B show example visual presentations 400A and 400B, respectively, in accordance with some embodiments.

Visualize 230 can visually organize information from graph database 225. In some embodiments, nodes that behave similarly can be clustered together (i.e., be put in a cluster). For example, when two nodes have similar edges (relationships) and behave in a similar fashion (e.g., run the same application, are associated with the same organization, and the like), the two nodes can be clustered together. Nodes that are clustered together can be visually presented as a shape (e.g., circle, rectangle, and the like) which denotes that there are a certain number of workloads fulfilling the same function, instead of presenting a shape for each workload in the cluster.

In various embodiments, visualize 230 can detect and present communities. Communities are workloads (e.g., of workloads 110_1,1-110_X,Yin FIG. 1) that have a close set of edges (relationships). The constituent workloads of a community do not have to be the same—they can each perform different functions, such as web server, database server, application server, and the like—but the workloads are densely connected. In other words, the nodes communicate with each other often and in high volume. Workloads in a community act collectively to perform an application, service, and/or business function. Instead of displaying a shape (e.g., circle, rectangle, and the like) for each of the hundreds or thousands of workloads in a community, the community can be represented by a single shape denoting the application performed, the number of constituent workloads, and the like.

Protect 240 can use information in the graph database 225 to design security policies. Security policies can implement security controls, for example, to protect an application wherever it is in a cloud computing environment (e.g., cloud computing environment 100 in FIG. 1). A security policy can specify what is to be protected (“nouns”), for example, applications run for a particular organization. A security policy can further specify a security intent (“verbs”), that is, how to protect. For example, a security intent can be to implement Payment Card Industry Data Security Standard (PCI DSS) network segmentation requirements (a regulatory requirement), implement a security best practices for databases, implement a whitelist architecture, and the like. By way of further example, a security intent can be specified in a template by a user (responsible for system administration, security, and the like).

Nouns and verbs can be described in a security template. A security template can include logic about how to process information in graph database 225 relating to workloads having a particular label/selection (nouns). Labels can be provided by logs 270 (e.g., layer 7 information), cloud control planes 280 (e.g., container orchestration), and CMDB 290. Protect 240 uses a security template to extract workloads to be protected (nouns) from graph database 225. Protect 240 further applies logic in the security template about how to protect the workloads (verbs) to produce a security policy. In various embodiments, security templates are JavaScript Object Notation (JSON) documents, documents in Jinja (or Jinja2), YAML Ain't Markup Language (YAML) documents, Open Policy Agent (OPA) rules, and the like. Jinja and Jinja2 are a web template engine for the Python programming language. YAML is a human-readable data-serialization language. OPA is an open source, general-purpose policy engine that enables unified, context-aware policy enforcement. Security templates are described further in U.S. patent application Ser. No. ______ (Attorney Docket No. PA9274US) filed ______, titled “Template-Driven Intent-Based Security,” which is hereby incorporated by reference for disclosure of generating a security policy using security templates.

Protect 240 can produce multiple security policies, each reflecting independent pieces of security logic that can be implemented by protect 240. In various embodiments, security policies are JavaScript Object Notation (JSON) documents which are described to a user (responsible for system administration, security, and the like) in natural language. A natural language is any language that has evolved naturally in humans through use and repetition without conscious planning or premeditation. Natural language can broadly be defined in contrast to artificial or constructed languages such as computer programming languages. The multiple security policies can be placed in an order of precedence to resolve potential conflicts. Visualize 230 can be used to visualize the security policy (or security policies), showing the workloads protected, permitted relationships, and prohibited relationships. Protect 240 can then be used to edit the security policy. For example, there can be a primary and backup server (e.g., of workloads 110_1,1-110_X,Yin FIG. 1). The backup server may have never been used and may not have the same edges (relationships) as the primary server in graph database 225. The security policy can be edited to give the backup server the same permissions as the primary server.

Protect 240 can validate a security policy. The security policy can be simulated using graph database 225. For example, a simulation can report which applications are broken (e.g., communications among nodes needed by the application to operate are prohibited) by the security policy, are unnecessarily exposed by weak policy, and the like. Security policy validation is described further in U.S. patent application Ser. No. ______ (Attorney Docket No. PA9275US) filed ______, titled “Validation of Cloud Security Policies,” which is incorporated by reference herein for disclosure of security policy validation.

Protect 240 can test a security policy. Protect can use historical data in graph database 225 to determine entropy in the cloud computing environment (e.g., cloud computing environment 100 in FIG. 1). For example, when a cloud computing environment first starts up, there are initially numerous changes as workloads are brought online and communicate with each other, such that entropy is high. Over time, the cloud computing environment becomes relatively stable with few changes, so entropy becomes low. In general, security policies are less reliable when entropy is high. Protect 240 can determine a level of entropy in the cloud computing environment and produce a reliability score and recommendation for the security policy. Security policy testing is described further in U.S. patent application Ser. No. ______ (Attorney Docket No. PA9276US) filed ______, titled “Reliability Prediction for Cloud Security Policies,” which is incorporated by reference herein for disclosure of security policy reliability prediction.

Protect 240 can deploy a security policy (or security policies). The security policy is deployed as needed in one or more cloud computing environments of cloud services 260₁-260_Z(e.g., Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP)), vArmour DSS Distributed Security System, VMware NSX, and the like). Protect 240 can provide the security policy to one or more of cloud drivers 250₁-250_Z. Cloud drivers 250₁-250_Zmaintain an inventory and topology (i.e., current state) of the workloads in the cloud computing environments hosted by cloud services 260₁-260_Z, respectively. Cloud drivers 250₁-250_Zcan use their respective inventory and topology to apply the security policy to the appropriate workloads, and respond immediately to changes in workload topology and workload placement.

Cloud drivers 250₁-250_Zcan serve as an interface between protect 240 (having a centralized security policy) and cloud services 260₁-260_Z. In other words, cloud drivers 250₁-250_Zimplement the security policy using the different facilities (e.g., application programming interfaces (APIs)) and capabilities available from cloud services 260₁-260_Z. For example, each of cloud services 260₁-260_Zcan have different syntax and semantics for implementing security controls. Moreover, each of cloud services 260₁-260_Zcan have different security capabilities (e.g., communications/connections between workloads can only be expressly permitted and not expressly prohibited), rule capacity (limit on the number of rules), optimization methods, and the like.

Cloud drivers 250₁-250_Zcan maintain the integrity of the security policy in the cloud computing environments hosted by cloud services 260₁-260_Z(referred to as the “cloud”). Cloud drivers 250₁-250_Zcan check that the security policy actually deployed in the cloud is as it should be, using the security policy's JSON source. When the security policy deployed in the cloud does not comport with the centralized security policy—such as when a bad actor logs into one of the cloud services and removes all the security rules—the responsible cloud driver (of cloud drivers 250₁-250_Z) can re-deploy the security policy and/or raise an operational alert. Where supported, cloud services 260₁-260_Zcan notify the respective cloud driver (of cloud drivers 250₁-250_Z) of changes to the topology and/or configuration. Otherwise, the respective cloud driver (of cloud drivers 250₁-250_Z) can poll the cloud service (cloud services 260₁-260_Z) to ensure the security rules are in place.

As described above, a security policy can be pushed down to the cloud computing environments hosted by cloud services 260₁-260_Zusing cloud drivers 250₁-250_Z, respectively. Additionally or alternatively, as new data comes into graph 220 as network logs 270, events 285 from cloud control plane 280, and inventory 295, protect 240 can check the new data against the security policy to detect violations and or drift (e.g., change in the environment and/or configuration).

Protect 240 can dynamically update a security policy as changes occur in the cloud computing environments hosted by cloud services 260₁-260_Z. For example, when a container (or pod) is deployed by container orchestration, it can be given a label, and cloud control plane 290 reports a container is deployed (as event 295). Labels can be predefined to specify identifying attributes of containers (and pods), such the container's application function. When the label corresponds to an attribute covered by an active (deployed) security policy, protect 240 can dynamically add the new container to the active security policy (as a target). For example, when a pod is deployed for a particular organization and there is an active policy for that organization, the new workload is added to the security policy. Similarly, when a container is killed, the workload is removed from the security policy. Dynamically updating security policy is described further in U.S. Pat. No. 9,521,115 issued Dec. 13, 2016, titled “Security Policy Generation Using Container Metadata,” which is hereby incorporated by reference for disclosure of dynamically updating security policy.

FIG. 5 shows method 500 for managing cloud security, according to some embodiments. Method 500 can be performed by system 200 (FIG. 2), including controller 210. Method 500 can commence at step 510 where data from a cloud computing environment (e.g., cloud computing environment 100 in FIG. 1) can be received. For example, graph 220 (FIG. 2) can receive streaming telemetry 275 from network logs 270, events 285 from cloud control plane 280, and inventory 295 from configuration management database (CMDB) 290.

At step 520, a graph database can be created or updated using the cloud data. For example, streaming telemetry 275, events 285, and inventory 295 (FIG. 2) can be normalized into a standard data format and stored in graph database 225.

At step 530, a visual representation of the cloud computing environment as modeled by the graph database can be provided. For example, visualize 230 (FIG. 2) can present a graph using data in graph database 225. In some embodiments, nodes (representing workloads in the cloud computing environment) can be clustered and/or placed in communities for visual clarity.

At step 540, a security template can be received. A security template can include logic about how to extract information from graph database 225 to identify workloads to be targets of a security policy. In addition, a security template can specify how the workloads are to be protected (e.g., security intent).

At step 550, a security policy can be created. For example, protect 240 can use the security template to extract information from graph database 225 (FIG. 2) to produce a security policy for the security intent of the security template.

At step 560, the security policy can be validated. For example, protect 240 (FIG. 2) tests the security policy against a historical data set stored in graph database 225. Protect 240 can generate a report around the risks and implications of the security policy being implemented.

At step 570, the security policy can be tested. For example, protect 240 (FIG. 2) can measure entropy and a rate of change in the data set stored graph database 225 to predict—when the security policy is deployed—the cloud computing environment (e.g., cloud computing environment 100 in FIG. 1) will change such that applications and/or services will break (e.g., be prevented from proper operation by the security policy).

At step 580, the security policy can be deployed to the cloud computing environment (e.g., cloud computing environment 100 in FIG. 1). For example, cloud drivers 250₁-250_Zcan produce requests, instructions, commands, and the like which are suitable for and accepted by cloud services 260₁-260_Z(respectively) to implement the security policy in the cloud computing environments hosted by cloud services 260₁-260_Z(respectively).

Optionally at step 580, the security policy can be maintained. For example, cloud drivers 250₁-250_Zcan make sure the security policy remains in force at the cloud computing environment hosted by a respective one of cloud services 260₁-260_Z. Optionally at step 580, the security policy can be dynamically updated as workloads subject to the deployed security policy are deployed and/or killed.

Although steps 510-580 are shown in a particular sequential order, various embodiments can perform steps 510-580 in different orders, perform some of steps 510-580 concurrently, and/or omit some of steps 510-580.

Some of the components provided in the computer system 600 in FIG. 6 can be those typically found in computer systems that may be suitable for use with embodiments of the present disclosure and are intended to represent a broad category of such computer components. Thus, the computer system 600 in FIG. 6 can be a personal computer (PC), hand held computer system, telephone, mobile computer system, workstation, tablet, phablet, mobile phone, server, minicomputer, mainframe computer, wearable, or any other computer system. The computer may also include different bus configurations, networked platforms, multi-processor platforms, and the like. Various operating systems may be used including UNIX, LINUX, WINDOWS, MAC OS, PALM OS, QNX ANDROID, IOS, CHROME, and other suitable operating systems.

Some of the above-described functions may be composed of instructions that are stored on storage media (e.g., computer-readable medium). The instructions may be retrieved and executed by the processor. Some examples of storage media are memory devices, tapes, disks, and the like. The instructions are operational when executed by the processor to direct the processor to operate in accord with the technology. Those skilled in the art are familiar with instructions, processor(s), and storage media.

In some embodiments, the computing system 600 may be implemented as a cloud-based computing environment, such as a virtual machine operating within a computing cloud. In other embodiments, the computing system 600 may itself include a cloud-based computing environment, where the functionalities of the computing system 600 are executed in a distributed fashion. Thus, the computing system 600, when configured as a computing cloud, may include pluralities of computing devices in various forms, as will be described in greater detail below.

In general, a cloud-based computing environment is a resource that typically combines the computational power of a large grouping of processors (such as within web servers) and/or that combines the storage capacity of a large grouping of computer memories or storage devices. Systems that provide cloud-based resources may be utilized exclusively by their owners or such systems may be accessible to outside users who deploy applications within the computing infrastructure to obtain the benefit of large computational or storage resources.

The cloud is formed, for example, by a network of web servers that comprise a plurality of computing devices, such as the computing system 600, with each server (or at least a plurality thereof) providing processor and/or storage resources. These servers manage workloads provided by multiple users (e.g., cloud resource customers or other users). Typically, each user places workload demands upon the cloud that vary in real-time, sometimes dramatically. The nature and extent of these variations typically depends on the type of business associated with the user.

It is noteworthy that any hardware platform suitable for performing the processing described herein is suitable for use with the technology. The terms “computer-readable storage medium” and “computer-readable storage media” as used herein refer to any medium or media that participate in providing instructions to a CPU for execution. Such media can take many forms, including, but not limited to, non-volatile media, volatile media and transmission media. Non-volatile media include, for example, optical, magnetic, and solid-state disks, such as a fixed disk. Volatile media include dynamic memory, such as system random-access memory (RAM). Transmission media include coaxial cables, copper wire and fiber optics, among others, including the wires that comprise one embodiment of a bus. Transmission media can also take the form of acoustic or light waves, such as those generated during radio frequency (RF) and infrared (IR) data communications. Common forms of computer-readable media include, for example, a floppy disk, a flexible disk, a hard disk, magnetic tape, any other magnetic medium, a CD-ROM disk, digital video disk (DVD), any other optical medium, any other physical medium with patterns of marks or holes, a RAM, a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), a Flash memory, any other memory chip or data exchange adapter, a carrier wave, or any other medium from which a computer can read.

Various forms of computer-readable media may be involved in carrying one or more sequences of one or more instructions to a CPU for execution. A bus carries the data to system RAM, from which a CPU retrieves and executes the instructions. The instructions received by system RAM can optionally be stored on a fixed disk either before or after execution by a CPU.

Computer program code for carrying out operations for aspects of the present technology may be written in any combination of one or more programming languages, including an object oriented programming language such as JAVA, SMALLTALK, C++ or the like and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The program code may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider).

The corresponding structures, materials, acts, and equivalents of all means or step plus function elements in the claims below are intended to include any structure, material, or act for performing the function in combination with other claimed elements as specifically claimed. The description of the present technology has been presented for purposes of illustration and description, but is not intended to be exhaustive or limited to the invention in the form disclosed.
