Abstract: In one embodiment, a method for managing ad hoc telepresence sessions is described. The method includes sensing a presence of a user in an ad hoc telepresence zone. The method also includes managing a list of contacts associated with the user. The method also includes determining an availability of a remote user at a remote telepresence zone. The remote user is selected from the list of contacts associated with the user. The method also includes displaying a list of available remote users. The method also includes initiating a telepresence session between the user and the remote user according to an input from the user to select the remote user from the list of available users.

Abstract: A Stateful Reference Monitor can be loaded into an existing commercial operating system, and then can regulate access to many different types of resources. The reference monitor maintains an updateable storage area whose contents can be used to affect access decisions, and access decisions can be based on arbitrary properties of the request.

Abstract: A system inserts at least one notifying identifier in the computer system. The at least one notifying identifier provides execution information associated with the computer system. The system receives execution information from the at least one notifying identifier, the execution information identifies details associated with a traffic flow on the computer system. The system then generates a signature based on a deterministic link provided by the execution information provided by the at least one notifying identifier. The signature is utilized to prevent further damage caused to the computer system by at least one attack.

Abstract: A system and method for detecting unauthorized boots and adjusting security policy. According to one embodiment of the present invention, the BIOS stores boot information in a data store from which it can later be distributed on a network and/or accessed by security software. The security software compares a signature of the operating system booted by the computer to a signature of a trusted, or authorized, operating system. The security software is capable of determining whether an attempted boot is authorized and can adjust security policy in response to the boot information.

Abstract: A system provides security to a computerized device by detecting a sequence of related processing operations within the computerized device and recording the sequence of related processing operations in a security history. The system identifies a security violation when a processing operation performed in the computerized device produces an undesired processing outcome that violates a security policy and subsequently detecting attempted performance of at least one processing operation that attempts to produce the undesired processing outcome that violates the security policy and in response, denies operation of the processing operation(s) within the computerized device to avoid violation of the security policy.
