International Classification:

H04L 9/32

US Classification:

726 2

Abstract:

An innovative security solution which separates a client into a Protected Context, which is the real files and resources of the client, and an Isolated Context, which is a restricted execution environment which makes use of virtualized resources to execute applications and modify content in the Isolated Context, without allowing explicit access to the resources in the Protected Context. The solution further consolidates user interfaces to allow users to seamlessly work with content in both contexts, and provide a visual indication of which display windows are rendered from content executed in the Isolated Context.

Abstract:

Embodiments of the invention relate to reading at least one locked, encrypted computer file encrypted by an encryption filter driver running on an operating system of a computer system, with an added kernel driver, while the operating system is running and reading at least one locked, unencrypted computer file in a computer system with an operating system with an added kernel driver while the operating system is running. An exemplary embodiment includes getting the handle of the locked, encrypted computer file, causing encryption key information associated with the locked, encrypted computer file to be processed, and reading data from the locked, encrypted computer file by using the added kernel driver.

International Classification:

G06F 17/30

US Classification:

707756, 707741, 707755, 707793, 707803

Abstract:

Embodiments of the invention relate to manipulating the original content of at least one original read-only computer file in a file-system of a computer system, where the computer system includes an operating system including a framework for in-line monitoring of accesses to the file-system. An exemplary embodiment, includes transforming the original content via a non-length-preserving data transformation algorithm, thereby resulting in transformed content, storing the transformed content in a transformed computer file, splitting the transformed computer tile into a first file and a second file, and associating the first file with the second file in the file-system. The non-length-preserving data transformation algorithm includes a length-increasing data transformation algorithm.

US Classification:

726 27, 713100, 717168

Abstract:

The present invention provides a processor-implemented method and system of updating an operating system of a computer system, where the operating system is subject to a system lockdown that does not allow changes to a list of approved executables of the operating system and that does not allow changes to a base system configuration of the operating system. In an exemplary embodiment, the method and system include, (1) identifying at least one trusted updater process in the operating system and (2) allowing the trusted updater process to make at least one change to the list of approved executables. In an exemplary embodiment, the method and system include, (1) identifying at least one trusted updater process in the operating system and (2) allowing the trusted updater process to make at least one change to the base system configuration.

US Classification:

370229000

Abstract:

Network recovery of multiple NEs, such as at NMS restart, or at re-establishment of communication after loss of communication with the NMS that provides reduced cost and reduced the elapsed time before the NMS can start performing network monitoring. A method of recovering data from a network element at a network management system comprises the steps of determining whether a data buffer of the network element is valid, if the data buffer of the network element is valid, determining whether the data buffer of the network element contains a database change event not received by the network management system, if the data buffer of the network element is not valid or if the data buffer of the network element contains a database change event not received by the network management system, indicating that the data buffer of the network element is out-of-sync with the network management system, and if the data buffer of the network element is valid and if the data buffer of the network element does not contains a database change event not received by the network management system, indicating that the data buffer of the network element is in sync with the network management system.

Abstract:

Data deduplication for data storage tapes comprises determining the read throughput of a deduplicated set of individual files on a single data storage tape, and determining a placement of deduplicated file data on a single data storage tape to reduce an average number of per-file gaps on the tape. Deduplicated file data is placed on the single data storage tape based on said placement to increase an average read throughput for a deduplicated set of individual files.
