US Classification:

726 25, 726 3, 726 23, 709224

Abstract:

Disclosed is a network hardening mechanism. The mechanism: generates a dependency graph from a multitude of exploits; constructs a goal conditions expression which may then be used to determine set(s) of safe network configurations. A subset of these safe network configuration sets may then be selected for implementation using hardening costs as a criterion.

Abstract:

Disclosed is a system for modeling, analyzing, and responding to network attacks. Machines are mapped to components, components are mapped to vulnerabilities, and vulnerabilities are mapped to exploits. Each of the exploits includes at least one precondition mapped to at least one postcondition. An attack graph which defines inter-exploit distances is generated using at least one of the exploits. The attack graph is aggregated. At least one hardening option is determined using the aggregated attack graph. Hardening options include applying at least one corrective measure to at least one initial condition, where the initial condition is the initial state of a precondition.

International Classification:

A61B 5/05

US Classification:

600410, 600407, 600411

Abstract:

Featured are devices for compression of target tissue while magnetic resonance imaging the target tissue and methods and systems related thereto. The method includes disposing target tissue between the fixed surface and the moveable member of a compression device and compressing the target tissue between the fixed surface and the moveable member. The method also includes acquiring one or more, more specifically a plurality, of sequences of image data of the compressed target tissue using an MRI imaging technique (MRI). In particular embodiments, the MRI technique is a SENC MRI technique, where tissue encoding is done prior to compressing the tissue and acquiring includes adding a gradient moment in the slice-selection direction to cause demodulation with a specific frequency. In further embodiments, the sequences of image data are acquired one of during successive periodic compressions of the tissue or successive periodic relaxation of the tissues.

Appl. No.:

13/949184

Inventors:

Michael W. JACOBS - Annapolis MD, US

Assignee:

ARINC INCORPORATED - Annapolis MD

International Classification:

H04L 29/06

US Classification:

370328

Abstract:

A system and method are provided for converting radio communication signals between a Digital Fixed Station Interface (DFSI) Internet Protocol (IP) APCO P25 standard communications format and binary serial data protocol standard communications. Received serial binary data may be evaluated, separated into control information and data payloads, and converted to DFSI IP standard data. Incoming and outgoing data communications are processed by implementing decisions about how to handle the information contained in, or to be contained in, the incoming and outgoing data communications based upon the substance, or overarching format, of the data contained in individual data packets, or serial bit streams. In embodiments, decisions and determinations regarding the information include determining that the information is damaged or corrupted and therefore not available to be converted. The data may be discarded based on such a determination.

International Classification:

H01Q 5/30
H01Q 21/28
H01Q 1/50

Abstract:

Systems and methods are disclosed to intelligently employ antenna resources in a manner that may reduce interference between communications signals even in instances where multiple separate frequency band communications need to be supported in a vehicle of limited size. A manifold antenna system is proposed that provides a scheme and a physical construct whereby multiple individual radio receiver/transmitter units may share a limited number of transmitting and receiving antennas. The disclosed manifold antenna system is particularly adaptable to aircraft, spacecraft, vessel or vehicle applications where there is limited room for mounting a number of individual antennas as may be needed to support each radio receiver/transmitter unit in an effort to minimize an amount of interference as is conventionally caused by having transmitting antennas located in too close a proximity to receiving antennas.

US Classification:

324 7619

Abstract:

A system and method are provided that advantageously combine Commercial-off-the shelf hardware and software components in a portable, ruggedized package for remotely monitoring radio-frequency (RF) spectrum activity with regard to a specific platform, structure or location for an extended duration. Provisions are made for remote access to, and analysis of, monitored spectrum activity data. The disclosed systems and methods evaluate spectrum usage over time, facilitate management and enforcement of spectrum allocations and restrictions, conduct extended spectrum surveillance, and analyze interference without on-site user involvement. RF spectrum analyzers, are connected to an onboard computer processing capacity, an integrated power supply, network backhaul connectivity components, and onboard diagnostic capabilities to support the remote unattended operation of the package. Data analysis components in communication with the remote package are used to generate custom graphs and reports for data reduction.
