Systems and methods are provided which implement a bridge server to provide user access to one or more secure applications. A bridge server of embodiments is disposed between a user and a secure application and invokes bridge server security protocols with respect to the user and secure application security protocols with respect to the secure application. In operation according to embodiments, client applications will link into a bridge server, the user will be authenticated by the bridge server, and a valid user will be correlated to an account of the secure application by the bridge server. Bridge servers of embodiments facilitate providing features with respect to secure application user access unavailable using the secure application security protocols.

Techniques are disclosed for implementing dynamic endpoint management. In accordance with one embodiment, whenever an endpoint joins a managed network for the first time, or rejoins that network, a local security module submits a list of applications (e.g., all or incremental) to a security server. The server validates the list and sends back a rule set (e.g., allow / block rules and / or required application security settings) for those applications. If the server has no information for a given application, it may further subscribe to content from a content provider or service. When the server is queried regarding an unknown application, the server sends a query to the service provider to obtain a trust rating for that unknown application. The trust rating can then be used to generate a rule set for the unknown application. Functionality can be shifted from server to client, and vice-versa if so desired.

Systems and methods for configuring and evaluating policies that direct processing of one or more data streams are described. A configuration interface is described for allowing users to specify object oriented policies. These object oriented policies may allow any data structures to be applied with respect to a payload of a received packet stream, including any portions of HTTP traffic. A configuration interface may also allow the user to control the order in which policies and policy groups are executed, in addition to specifying actions to be taken if one or more policies are undefined. Systems and methods for processing the policies may allow efficient processing of object-oriented policies by applying potentially complex data structures to unstructured data streams. A device may also interpret and process a number of flow control commands and policy group invocation statements to determine an order of execution among a number of policies and policy groups. These policy configurations and processing may allow configuration and processing of complex network behaviors relating to load balancing, VPNs, SSL offloading, content switching, application security, acceleration, and caching.

A computer system provides system-wide computer application security using role-based identifiers. The programmer identifies secured functions within a software application using a hierarchical identifier. The hierarchical identifiers are grouped together into privilege sets. The privilege sets and other hierarchical identifiers are grouped together into job functions, which are in turn grouped into larger subsets called user roles. These user roles are stored in a data store. User identifiers are created. Each user identifier is linked to one user role in the data store. A surrogate identifier is created to correspond to each user role and is stored in the data store. The surrogate identifiers are not disclosed to the users. A user is given permission to access secured functions within an application by retrieving a surrogate identifier from the data store, which shares the same user role as the user. Access rights are determined using the surrogate identifier to validate permissions on a security provider.

To control privileges and access to resources on a per-process basis, an administrator creates a rule that may be applied to modify a process's token. The rule includes an application-criterion set and changes to be made to the groups and / or privileges of a token. The rule is set as a policy within a group policy object (GPO), where a GPO is associated with one or more groups of computers. When a GPO containing a rule is applied to a computer, a driver installed on the computer accesses the rule(s) anytime a logged-on user executes a process. If the executed process satisfies the criterion set of a rule the changes contained within the rule are made to the process token, and the user has expanded and / or contracted access and / or privileges for only that process.

A cooperative processing and escalation method and system for use in multi-node application-layer security management is disclosed. The method includes the steps of identifying individual application security nodes, grouping and configuring nodes for cooperative processing, assigning the default operational mode at each node, assignment of logging and alert event tasks at each node, and defining escalation and de-escalation rules and triggers at each node. Both loosely-coupled and tightly-coupled configurations, each with its cooperative processing model, are disclosed. The method includes provision for central console configuration and control, near real-time central console dashboard operations interface, alert notification, and operator override of operational modes and event tasks.

A system is configured to receive a list of applications installed on a user device; obtain application profiles that identify risk levels associated with the applications; obtain a user profile that identifies a job level, security risk level, or an access level to confidential information associated with the user of the user device; identify a highest risk level authorized for the user device based on whether the job level is greater than a first threshold, the security risk level is greater than a second threshold, or the access level is greater than a third threshold; determine whether any of the risk levels are greater than the highest risk level; and transmit a notification that one of the applications is to be removed from the user device when one of the risk levels, associated with the one of the applications, is greater than the highest risk level.

Techniques for facilitating the reuse of a browser-based thin client of a client-server application in a browser-independent context. These techniques may be used, for instance, to integrate the functionality of a browser-based thin client in a desktop-based, rich client infrastructure. In one set of embodiments, these techniques include determining one or more browser dependencies that require the thin client to operate within a web browser. For example, the thin client may depend on a web browser to handle application security, the loading / caching of client-side files, the receipt / passing of application parameters, and the like. These browser dependencies are then eliminated. As a result, the thin client can be subsequently reused without the presence of a web browser. In one set of embodiments, this process is performed by a conversion utility that automatically converts program code for the browser-based thin client into program code for a browser-independent client application.

A system for authenticating the user of a computing device comprises an authorized user directory. Each record is uniquely associated with an authorized user and includes at least a computing device ID value that is a globally unique value assigned to the authorized user's computing device, a group of unique depictions such as photographs, an identification of a key depiction. Portions of each image form fiducials recognizable by the user. The record further includes trace pattern verification data representing continuous trace strokes between pairs of the fiducials within the key depiction. To authenticate, the group of images are displayed to the user. The user must first select the key image and secondly trace continuous trace strokes between the pairs of fiducials to match the trace pattern verification data.

A method provides policy based adaptive application capability management and device attestation for dynamic control of remote device operations. The method includes instrumenting applications installed on a remote device to examine their runtime application programming interface (API) invocations to trusted functions abstracted by a trusted services platform anchored to an underlying firmware, software or hardware root of trust, and managing the application security operations based on the execution context and dynamic privilege controls to restrict their capabilities. The invention also provides a local attestation agent to perform state measurements for platform trust, configuration and operational metrics, and generates device policy based platform and application level alerts. These alerts allow operations technology (OT) administrators to dynamically control the operational capabilities of applications, to deal with discovered vulnerabilities and exploits, before requiring distribution of application software upgrades or patches onto a large number of distributed remote devices.

Verifying application security vulnerabilities includes receiving a source code to analyze, performing a static analysis using the received source code and generating a vulnerability call trace for the received source code. Responsive to a determination that all static analysis results are not validated, mock objects are generated using the vulnerability call trace and a unit test is created using the generated mock objects. The unit test is executed using the generated mock objects and responsive to a determination that an identified vulnerability was validated; a next static analysis result is selected. Responsive to a determination that all static analysis results are validated, results and computed unit tests are reported.

The present system allows disparate secure applications to communicate directly with one another in a heterogeneous application environment by providing for the creation of tokens that can be passed between the applications without human intervention. Security information is passed between applications in the form of a token with a string data type. Since a string is a primitive data type, it can be recognized by a large number of applications and interfaces. The token has no header and therefore no application-specific header configuration, making it platform and technology independent. This eliminates the need for conversion of security information between different formats. The use of tokens also eliminates the need for an application to be authenticated and authorized every time it sends a message to another application. Instead of a permanent context or session, a context is created with every invocation from one application to another.

Group Virtual Private Networks (Group VPNS) are provided for different types of machines in a data processing network. Security groups are defined by a security policy for each member. Security policies and encryption keys are deployed to members of a security group using an IPSec network infrastructure with authentication via VPN mechanisms. The group VPNs provide a trusted IP network that can leverage and co-exist with security access control technologies, such as endpoint security that controls client network access or application security that controls user access to enterprise applications.

System and method for accurately determining security policy for an application based on dynamic code analysis of application runtime execution(s). A dynamic recorder, dynamic code analyzer and security policy analyzer can evaluate and determine the security decisions and access to secure resources made during a security event within one or more executions of an application in order to identify an existing security policy that best matches an application's security needs. Security events may be analyzed to determine which security decisions and access to secure resources are necessary and which can be eliminated or replaced with alternative decisions or resources.

In one embodiment, methods are described to provide a binary translation and randomization system. Relocation metadata is received, which comprises, for each of a plurality of execution units in an executable file, a mapping from the executable file into an address space range. For at least one of the plurality of execution units, the mapping is modified to replace instructions within the address space range with a relocated copy of the instructions at a randomly located address space range. An order of the plurality of execution units may thus be modified. An image is generated from the executable file using the relocation metadata, and an execution of the image is caused. The randomization may be carried out in two passes to provide executable files that are uniquely randomized for each computer and for each execution.
