A method for verifying a set of policy instructions to be used by a policy decision point (PDP) in adjudicating access requests to protected resources. The policy instructions are in the form of Horn clauses or conditional tag-expressions that are validated against a known test policy or desired outcome. The policy instructions are then compiled into aggregate form. When a plurality of policy instructions creates a conflict, the policy instructions are hierarchically organized to resolve said conflict.

System and method for secure, policy-based access control for mobile computing devices

A system for controlling file access on a mobile computing device. Policy conditions are held at a policy decision point (PDP) and can be dynamically modified at run-time. Access requests to a file or set of files are intercepted by an agent that subsequently brokers the adjudication of said request via a secure, encrypted and hidden back-channel where the requestor is never allowed access to or knowledge of either the adjudication process or the parameters associated with adjudication. The PDP then returns either an access approval or denial based on said policy conditions.

A system and methods for context-aware and situation-aware secure, policy-based access control for computing devices. The invention enhances the previously disclosed policy-based control system by adding contextual information to the set of resources by which a policy decision point can adjudicate a query to execute a transaction or to access a secure resource. Policy information points are able to store information collected over time related to resources under the control of the system. The system can further include an analytical processing engine capable of inferring new information from existing information that also can be used by the decision points. The policy information points provide context to the decision. They are also able to consider and include information that is external to the system or detected outside the system itself.

System and methods for context-aware and situation-aware secure, policy-based access control for computing devices

A system and method for policy-based active Data Loss Prevention (DLP) using a two-step process to first determine if an attempt to access a data object is governed by DLP policy, and if so, then applying the DLP policy to either allow or deny access. Attempts by an agent to access, create, modify, or distribute a data object are trapped by a policy execution point. A first query determines if DLP policies govern that access request. If they do, then the metadata is decrypted to form a second query to a policy decision point to adjudicate the access request. If the access request is allowed, then a second key is provided to decrypt the data object for further processing. The system further provides for the encryption of unencrypted data objects to protect them for all future access queries.

System and methods for policy-based active data loss prevention

Systems and methods for secure, policy-based, access control and management of mobile computing devices, including policy decision enforcement mechanisms, device and private network presence testing, aspects of file system controls, policy set sanity checking algorithms, performance optimizations.

An autonomous and adaptive method and system for secure, policy-based control of remote and locally controlled computing devices. The invention uses a policy-based access control mechanism to achieve adaptive and dynamic behavior modification based on the context of the local operating environment of the computing device. The modification system assesses the desirability of actions or outcomes as determined by the policy rules and modifies them accordingly, thus altering the behavior of the computing device. The system can utilize a machine learning technique, pattern matching and heuristic evaluation. When applied to the control of robotic and autonomous devices, the system allows the robot to offload adjudication to a remote system and also facilitates cooperative behaviors between robots operating in dynamic environments.
