Oct 17, 2005

Appl. No.:

11/250449

International Classification:

G06F 12/14
G06F 7/04
G06F 15/173

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.

Appl. No.:

7/947256

Inventors:

Michael Jacobs - Groton MA

Assignee:

Iris Graphics, Inc. - Bedford MA

International Classification:

H04N 146

US Classification:

395109

Abstract:

A system fop matching a first picture on a monitor to a second picture printed on a printing medium. The system includes a) a monitor for receiving a first image and for displaying the first image as the first picture, b) printing apparatus for receiving a second image and for producing the second picture and c) conversion apparatus for converting first colors of the first image, defined in a first color coordinate system of the monitor, to second colors of the second image, defined in a second color coordinate system of the printing apparatus and the printing medium, through third colors defined in a colorimetric color coordinate system, to convert from the first image to the second image.

Filed:

Dec 17, 1976

Appl. No.:

5/751490

Inventors:

Sandra Rae Vowles - Denver CO
Michael Alan Jacobs - Denver CO
Amos Ray Jackson - Salt Lake City UT

International Classification:

H04M 518

US Classification:

179 27DA

Abstract:

An apparatus identifying a class of called telephone lines by extending an identity signal back over the called line to a calling central operator or control. The identifier apparatus includes a signal identity generator connected to the called line, a signal decoder located at a calling central control such as an operator cordboard or traffic service position (TSPS), and a time-out for deactivating the generator after a predetermined time period has elapsed. A method is also set forth where a uniquely coded signal is extended over the communication line to an operator when an "OFF HOOK" condition appears from the called line to warn the operator that the called line is not authorized to receive collect calls.

International Classification:

G06F 16/23

Abstract:

Computer program products, methods, systems, apparatus, and computing entities are provided for creating and using heterogeneous pools of validators to implement blockchain consensus. The specialized validators can be segmented and pooled based on their roles and functionalities in the consensus mechanism.
