Patent number: 8881288Abstract: A method of generating graphical models for providing security analysis in computer networks that in one embodiment includes the steps of generating a type abstract graph independent of particular networks that models abstract dependency relationships among attributes and exploits; generating network-specific attack graphs by combining the type abstract graph with specific network information; monitoring an intruder alert; and generating a real-time attack graph by correlating the intruder alert with the network-specific attack graph. The real-time attack graph can be generated using reachability checking, bridging, and exploit prediction based on consequence alerts and may further include the step of calculating the likelihood of queries using a Bayesian network model. The method may also include the steps of inferring unobserved attacks that may have been missed by intrusion detection sensors, and projecting on which hosts and using what exploits additional intruder attacks may occur.Type: GrantFiled: October 28, 2009Date of Patent: November 4, 2014Assignee: Intelligent Automation, Inc.Inventors: Renato Levy, Hongjun Li, Peng Liu, Margaret Lyell

Publication number: 20120244940Abstract: An interactive display system including a wireless pointing device including a camera or other video capture system. The pointing device captures images displayed by the computer, including one or more human-imperceptible positioning targets. The positioning targets are presented as patterned modulation of the intensity (e.g., variation in pixel intensity) in a display frame of the visual payload, followed by the opposite modulation in a successive frame. At least two captured image frames are subtracted from one another to recover the positioning target in the captured visual data and to remove the displayed image payload. The location, size, and orientation of the recovered positioning target identify the aiming point of the remote pointing device relative to the display. Another embodiment uses temporal sequencing of positioning targets (either human-perceptible or human-imperceptible) to position the pointing device.Type: ApplicationFiled: June 8, 2012Publication date: September 27, 2012Applicant: INTERPHASE CORPORATIONInventors: Yoram Solomon, Robert Finis Anderson, III, Hongjun Li, Gregory Brian Kalush
