Methods for managing security tokens based on security violations and devices thereof

Abstract

Methods, non-transitory computer readable media, and network traffic manager apparatus that assists managing security tokens based on security violations includes monitoring network traffic data between a client and a web application server. Next, the monitored network traffic data is determined for at least one security violation. One or more access tokens associated with the client is modified when the at least one security violation is detected in the monitored network traffic data. The client is restricted from accessing one or more web applications based on the modified one or more access tokens.

Description

BACKGROUND

In a federated environment, when a user accesses a protected application, the user is authenticated by an identity provider (IDP) and redirected back to the client application with an authorization grant code. The client application retrieves an access token using the authorization grant from the IDP. The access token is verified and used for providing access control to the protected resources. The user might require different tokens to access different applications. IDP keeps track of all the issued access tokens and controls access to the applications.

Management of tokens and security around token handling are major concerns for administrators managing these federated identity environments. Often a manual process is used by administrator to identify and act on any revoke compromised tokens in the system. Accordingly, this manual approach causes delay in mitigating security threats.

By way of example only, the optional configurable logic hardware device 21 may comprise one or more of field programmable gate arrays (“FPGAs”), field programmable logic devices (“FPLDs”), application specific integrated circuits (ASICs”) and/or programmable logic units (“PLUs”).

The communication system 24 in the network traffic manager apparatus 14 is used to operatively couple and communicate between the network traffic manager apparatus 14, the plurality of client computing devices 12(1)-12(n), the IDP server 13, and the plurality of web application servers 16(1)-16(n) which are all coupled together by communication network 30 such as one or more local area networks (LAN) and/or the wide area network (WAN), although other types and numbers of communication networks or systems with other types and numbers of connections and configurations to other devices and elements may be used. By way of example only, the communication network such as local area networks (LAN) and the wide area network (WAN) can use TCP/IP over Ethernet and industry-standard protocols, including NFS, CIFS, SOAP, XML, LDAP, and SNMP, although other types and numbers of communication networks, can be used. In this example, the bus 26 is a PCI Express bus in this example, although other bus types and links may be used.

Each of the plurality of client computing devices 12(1)-12(n) of the network traffic management system 10, include a central processing unit (CPU) or processor, a memory, input/display device interface, configurable logic device and an input/output system or I/O system, which are coupled together by a bus or other link. The plurality of client computing devices 12(1)-12(n), in this example, may run interface applications, such as Web browsers, that may provide an interface to make requests for and send and/or receive data to and/or from the web application servers 16(1)-16(n) via the network traffic manager apparatus 14. Additionally, the plurality of client computing devices 12(1)-12(n) can include any type of computing device that can receive, render, and facilitate user interaction, such as client computers, network computer, mobile computers, mobile phones, virtual machines (including cloud-based computer), or the like. Each of the plurality of client computing devices 12(1)-12(n) utilizes the network traffic manager apparatus 14 to conduct one or more operations with the web application servers 16(1)-16(n), such as to obtain data and/or access the applications from one of the web application servers 16(1)-16(n), by way of example only, although other numbers and/or types of systems could be utilizing these resources and other types and numbers of functions utilizing other types of protocols could be performed.

The IDP server 13 of the network traffic management system include a central processing unit (CPU) or processor, a memory, and a communication system, which are coupled together by a bus or other link, although other numbers and/or types of network devices could be used. Generally, the IDP server 13 assists with generating and providing access tokens, via the communication network 30 according to the HTTP-based application RFC protocol or the CIFS or NFS protocol in this example, but the principles discussed herein are not limited to this example and can include other application protocols. A series of applications may run on the IDP server 13 that allows the transmission of data requested by the network traffic manager apparatus 14. It is to be understood that the IDP server 13 may be hardware or software or may represent a system with multiple external resource servers, which may include internal or external networks. In this example the IDP server 13 may be any version of Microsoft® IIS servers or Apache® servers, although other types of servers may be used.

Each of the plurality of web application servers 16(1)-16(n) of the network traffic management system include a central processing unit (CPU) or processor, a memory, and a communication system, which are coupled together by a bus or other link, although other numbers and/or types of network devices could be used. Generally, the plurality of web application servers 16(1)-16(n) process requests for providing access to one or more enterprise web applications received from the plurality of client computing devices 12(1)-12(n), network traffic manager apparatus 14, via the communication network 30 according to the HTTP-based application RFC protocol or the CIFS or NFS protocol in this example, but the principles discussed herein are not limited to this example and can include other application protocols. A series of applications may run on the plurality web application servers 16(1)-16(n) that allows the transmission of applications requested by the plurality of client computing devices 12(1)-12(n), or the network traffic manager apparatus 14. The plurality of web application servers 16(1)-16(n) may provide data or receive data in response to requests directed toward the respective applications on the plurality web application servers 16(1)-16(n) from the plurality of client computing devices 12(1)-12(n) or the network traffic manager apparatus 14. It is to be understood that the plurality of web application servers 16(1)-16(n) may be hardware or software or may represent a system with multiple external resource servers, which may include internal or external networks. In this example the plurality of web application servers 16(1)-16(n) may be any version of Microsoft® IIS servers or Apache® servers, although other types of servers may be used.

Although the plurality of web application servers 16(1)-16(n) are illustrated as single servers, one or more actions of the IDP server 13 and each of the plurality of web application servers 16(1)-16(n) may be distributed across one or more distinct network computing devices. Moreover, the plurality of web application servers 16(1)-16(n) are not limited to a particular configuration. Thus, the plurality of plurality web application servers 16(1)-16(n) may contain a plurality of network computing devices that operate using a master/slave approach, whereby one of the network computing devices of the plurality of web application servers 16(1)-16(n) operate to manage and/or otherwise coordinate operations of the other network computing devices. The plurality of web application servers 16(1)-16(n) may operate as a plurality of network computing devices within cluster architecture, a peer-to peer architecture, virtual machines, or within a cloud architecture.

Thus, the technology disclosed herein is not to be construed as being limited to a single environment and other configurations and architectures are also envisaged. For example, the one or more of the plurality of web application servers 16(1)-16(n) depicted in FIG. 1 can operate within network traffic manager apparatus 14 rather than as a stand-alone server communicating with network traffic manager apparatus 14 via the communication network(s) 30. In this example the plurality of web application servers 16(1)-16(n) operate within the memory 20 of the network traffic manager apparatus 14.

While the network traffic manager apparatus 14 is illustrated in this example as including a single device, the network traffic manager apparatus 14 in other examples can include a plurality of devices or blades each with one or more processors each processor with one or more processing cores that implement one or more steps of this technology. In these examples, one or more of the devices can have a dedicated communication interface or memory. Alternatively, one or more of the devices can utilize the memory, communication interface, or other hardware or software components of one or more other communicably coupled of the devices. Additionally, one or more of the devices that together comprise network traffic manager apparatus 14 in other examples can be standalone devices or integrated with one or more other devices or applications, such as one of the IDP server 13, plurality of web application servers 16(1)-16(n) or, the network traffic manager apparatus 14, or applications coupled to the communication network(s), for example. Moreover, one or more of the devices of the network traffic manager apparatus 14 in these examples can be in a same or a different communication network 30 including one or more public, private, or cloud networks, for example.

Although an exemplary network traffic management system 10 with the plurality of client computing devices 12(1)-12(n), the IDP server 13, the network traffic manager apparatus 14, and the plurality of web application servers 16(1)-16(n), communication networks 30 are described and illustrated herein, other types and numbers of systems, devices, blades, components, and elements in other topologies can be used. It is to be understood that the systems of the examples described herein are for exemplary purposes, as many variations of the specific hardware and software used to implement the examples are possible, as will be appreciated by those skilled in the relevant art(s).

Further, each of the systems of the examples may be conveniently implemented using one or more general purpose computer systems, microprocessors, digital signal processors, and micro-controllers, programmed according to the teachings of the examples, as described and illustrated herein, and as will be appreciated by those of ordinary skill in the art.

One or more of the components depicted in the network traffic management system, such as the network traffic manager apparatus 14, the plurality of client computing devices 12(1)-12(n), the IDP server 13, the plurality of web application servers 16(1)-16(n), for example, may be configured to operate as virtual instances on the same physical machine. In other words, one or more of network traffic manager apparatus 14, the IDP server 13, the plurality of client computing devices 12(1)-12(n), or the plurality of web application servers 16(1)-16(n) illustrated in FIG. 1 may operate on the same physical device rather than as separate devices communicating through a network as depicted in FIG. 1. There may be more or fewer plurality of client computing devices 12(1)-12(n), the IDP server 13, network traffic manager apparatus 14, or the plurality of web application servers 16(1)-16(n) than depicted in FIG. 1. The plurality of client computing devices 12(1)-12(n), the IDP server 13, the plurality of web application servers 16(1)-16(n) could be implemented as applications on network traffic manager apparatus 14.

In addition, two or more computing systems or devices can be substituted for any one of the systems or devices in any example. Accordingly, principles and advantages of distributed processing, such as redundancy and replication also can be implemented, as desired, to increase the robustness and performance of the devices and systems of the examples. The examples may also be implemented on computer system(s) that extend across any suitable network using any suitable interface mechanisms and traffic technologies, including by way of example only teletraffic in any suitable form (e.g., voice and modem), wireless traffic media, wireless traffic networks, cellular traffic networks, G3 traffic networks, Public Switched Telephone Network (PSTNs), Packet Data Networks (PDNs), the Internet, intranets, and combinations thereof.

The examples may also be embodied as a non-transitory computer readable medium having instructions stored thereon for one or more aspects of the technology as described and illustrated by way of the examples herein, which when executed by a processor (or configurable hardware), cause the processor to carry out the steps necessary to implement the methods of the examples, as described and illustrated herein.

An example of a method for managing security tokens based on security violations will now be described with reference to FIGS. 1-4. Particularly with reference to FIGS>3-4, in step 305, the network traffic manager apparatus 14 receives a request from one of the plurality of client computing devices 12(1)-12(n) to access a web application in the plurality of web applications 16(1)-16(n), although the network traffic manager apparatus 14 can receive other types of requests from other devices.

Next in step 310, the network traffic manager apparatus 14 determines when the received request includes an access token. Accordingly, when the network traffic manager apparatus 14 determines that the received request includes the access token, then the Yes branch is taken to step 330 which will further be illustrated below. However, when the network traffic manager apparatus 14 determines that the received request does not include the received token, then the No branch is taken to step 315.

Next in step 315, the network traffic manager apparatus 14 redirects the requesting one of the plurality of client computing devices 12(1)-12(n) to the IDP server 13 for the purpose of authentication. In this example, the requesting one of the plurality of client computing devices 12(1)-12(n) provides the IDP server 13 with the necessary credentials to access the web application. The IDP server then determines the validity of the credentials and when it is determined that the credentials are valid, provides the requesting one of the plurality of client computing devices 12(1)-12(n) with the authorization grant code. Finally, the IDP server 13 redirects the requesting one of the plurality of client computing devices 12(1)-12(n) back to the network traffic manager apparatus 14. While this example illustrates the IDP server 13 performing the step of authentication, in other examples the network traffic manager apparatus 14 can perform the step of authentication and generating the authorization grant code. Alternatively, the network traffic manager apparatus 14 can obtain the required data from the requesting one of the plurality of client computing devices 12(1)-12(n) to authenticate the obtained data from the requesting one of the plurality of client computing devices 12(1)-12(n) with the IDP server 13 directly instead of redirecting the request to the IDP server 13.

In step 320, the network traffic manager apparatus 14 receives the authorization grant code from the requesting one of the plurality of client computing devices 12(1)-12(n), although the network traffic manager apparatus 14 can receive other types or amounts data from the requesting client computing device confirming the authentication.

Next in step 325, the network traffic manager apparatus 14 obtains an access token from the IDP server 13 using the authorization grant code, although the network traffic manager apparatus 14 can obtain the access token using other types or amounts of information. Alternatively in another example, the network traffic manager apparatus 14 can generate the access token using the authorization grant code.

In step 330, the network traffic manager apparatus 14 authenticates the obtained or received (from the request in step 305) access token with the IDP server 13, although the network traffic manager apparatus 14 can authenticate the obtained access token using other techniques. In this example, the network traffic manager apparatus 14 authenticates the access token by determining if the requesting one of the plurality of client computing devices 12(1)-12(n) has the required rights to access the web application and also determines whether the time period of the access token has expired by checking with the IDP server 13, although the network traffic manager apparatus 14 can use other techniques to authenticate the access token.

Next in step 335, the network traffic manager apparatus 14 determines when the received access token is valid. By way of example, the network traffic manager apparatus 14 can if the token has expired and/or whether the requesting one of the plurality of client computing devices 12(1)-12(n) has the access rights to use the application, although the network traffic manager apparatus 14 can determine the validity using other techniques. Accordingly, when the network traffic manager apparatus 14 determines that the access token is not valid, then the No branch is taken to step 365 where the exemplary method ends. However, when the network traffic manager apparatus 14 determines that the access token is valid, then the Yes branch is taken to step 340.

In step 340, the network traffic manager apparatus 14 provides access to the requesting one of the plurality of client computing devices 12(1)-12(n) based on the access token, although the network traffic manager apparatus 14 can provide the access using other types or amounts of data.

In step 345, the network traffic manager apparatus 14 monitors the network traffic between the requesting one of the plurality of client computing devices 12(1)-12(n) and one of the plurality of web application servers 16(1)-16(n) on which the web application accessed by the client computing device resides. In this example, the network traffic manager apparatus 14 monitors the network traffic to detect violations such as access control list denials, distributed denial of service attacks, SQL injection threat, content leakage, although the network traffic manager apparatus 14 can monitor the network traffic for other types or amounts of violations.

Next in step 350, the network traffic manager apparatus 14 determines if there are any security violations while the requesting one of the plurality of client computing devices 12(1)-12(n) access the requested web application in the plurality of web application servers 16(1)-16(n). When the network traffic manager apparatus 14 determines that no security violation was detected, then the No branch is taken back to step 345 where the network traffic manager apparatus 14 continues to monitor the network traffic. However, when the network traffic manager apparatus 14 determines that there is at least one security violation identified, then the Yes branch is taken to step 355.

In step 355, the network traffic manager apparatus 14 sends the data relating to the determined security violation to the IDP server 13, although the network traffic manager apparatus 14 can send other types or amounts of information.

In step 360, the network traffic manager apparatus 14 assists the IDP server 13 with either modifying and/or revoking the access token that was provided to the requesting one of the plurality of client computing devices 12(1)-12(n). By revoking the access token in this example, the requesting one of the plurality of client computing devices 12(1)-12(n) will not have access to the web application. Additionally in this example, all the previous access tokens that were provided to the requesting one of the plurality of client computing devices 12(1)-12(n) for any other web application can also be revoked and/or modified when the security violation is detected. Alternatively in another example, the network traffic manager apparatus 14 can revoke and/or modify the access tokens. In other examples, the network traffic manager apparatus 14 can modify the access rights present in the access token to provide restricted access to the requesting one of the plurality of client computing devices 12(1)-12(n) when a security violation is detected, although other types of actions could be enforced on the requesting one of the plurality of client computing devices 12(1)-12(n). The exemplary method ends in step 365.

Having thus described the basic concept of the technology, it will be rather apparent to those skilled in the art that the foregoing detailed disclosure is intended to be presented by way of example only, and is not limiting. Various alterations, improvements, and modifications will occur and are intended to those skilled in the art, though not expressly stated herein. These alterations, improvements, and modifications are intended to be suggested hereby, and are within the spirit and scope of the technology. Additionally, the recited order of processing elements or sequences, or the use of numbers, letters, or other designations therefore, is not intended to limit the claimed processes to any order except as may be specified in the claims.
