System and method for maintaining security in a distributed computer network

Abstract: A system and method for maintaining security in a distributed computing environment comprises a policy manager located on a server for managing and distributing a security policy, and an application guard located on a client for managing access to securable components as specified by the security policy. In the preferred embodiment, a global policy specifies access privileges of the user to securable components. The policy manager may then preferably distribute a local client policy based on the global policy to the client. An application guard located on the client then manages access to the securable components as specified by the local policy.

Maintaining security in a distributed computer network

Abstract: A system and method for maintaining security in a distributed computing environment comprises a policy manager (210) located on a server for managing and distributing a security policy, and an application guard (426) located on a client for managing access to securable components as specified by the security policy. In the preferred embodiment, a global policy specifies access privileges of the user to securable components. The policy manager (210) may then preferably distribute a local client policy (318) based on the global policy to the client. An application guard (426) located on the client then manages access to the securable components as specified by the local policy (318).

Information record infrastructure, system and method

Abstract: A method of maintaining digital medical records, comprising a step of receiving a medical transaction record (102), encrypted with a key in accordance with a patient-file association. Also comprising a step of accessing the encrypted medical transaction record according to a patient association with the record (111). And further comprising a step of re-encryption of the encrypted accessed medical transaction record with a key associated with an intended recipient of the medical record. The system and method according to the present invention presents a new business model for creation, maintenance, transmission, and use of medical records. The invention also allows financial burdens to be reallocated optimally and equitably, resulting in decreased overall societal cost and providing a successful business model for a database proprietor. Secure entrusted medical records are held in trust by an independent third party on behalf of the patient (113), and serve the medical community at large. Separately encrypted record elements may be aggregated as an information polymer.

System and method for secure three-party communications

Abstract: A system and method for communicating information between a first party and a second party, comprising the steps of receiving, by an intermediary, an identifier of desired information and accounting information for a transaction involving the information from the first party, transmitting an identifier of the first party to the second party, and negotiating, by the intermediary, a comprehension function for obscuring at least a portion of the information communicated between the first party and the second party. The data transmission may be made secure with respect to the intermediary by providing an asymmetric key or direct key exchange for encryption of the communication between the first and second party. The data transmission may be made secure with respect to the second party by maintaining the information in encrypted format at the second party, with the decryption key held only by the intermediary, and transmitting a secure composite of the decryption key and a new encryption key to the second party for transcoding of the data record, and providing the new decryption key to the first party, so that the information transmitted to the first party can be comprehended by it.

Probabilistic Alert Correlation

Abstract: With the growing deployment of host and network intrusion detection systems, managing reports from these systems becomes critically important. We present a probabilistic approach to alert correlation, extending ideas from multisensor data fusion. Features used for alert correlation are based on alert content that anticipates evolving IETF standards. The probabilistic approach provides a unified mathematical framework for correlating alerts that match closely but not perfectly, where the minimum degree of match required to fuse alerts is controlled by a single configurable parameter. Only features in common are considered in the fusion algorithm. For each feature we define an appropriate similarity function. The overall similarity is weighted by a specifiable expectation of similarity. In addition, a minimum similarity may be specified for some or all features. Features in this set must match at least as well as the minimum similarity specification in order to combine alerts, regardless of the goodness of match on the feature set as a whole. Our approach correlates attacks over time, correlates reports from heterogeneous sensors, and correlates multiple attack steps.

Policy-Based Application Management

Abstract: Improved techniques for managing enterprise applications on mobile devices are described herein. Each enterprise mobile application running on the mobile device has an associated policy through which it interacts with its environment. The policy selectively blocks or allows activities involving the enterprise application in accordance with rules established by the enterprise. Together, the enterprise applications running on the mobile device form a set of managed applications. Managed applications are typically allowed to exchange data with other managed applications, but are blocked from exchanging data with other applications, such as the user's own personal applications. Policies may be defined to manage data sharing, mobile resource management, application specific information, networking and data access solutions, device cloud and transfer, dual mode application software, enterprise app store access, and virtualized application and resources, among other things.

System for regulating access to and distributing content in a network

Abstract: There is provided a system for regulating access and managing distribution of content in a network, such as the Internet. The system includes communication gateways, installed at a subscriber site, internet control points, installed remotely, and various network elements installed throughout the network. The communication gateways and network elements operate in conjunction with the internet control points to restrict or allow access to specified Internet sites and to manage efficient distribution of content such as music, video, games, broadband data, real-time audio and voice applications, and software to subscribers.
