US Patent:

20210273967, Sep 2, 2021

Filed:

Jun 26, 2019

Appl. No.:

16/453212

Inventors:

- McLean VA, US
Justin HOFFMAN - Boerne TX, US

Assignee:

Booz Allen Hamilton Inc. - McLean VA

International Classification:

H04L 29/06

Abstract:

A system for generating a cyber-attack to penetrate a network. The system includes an identification module configured to identify at least one vulnerability of the network by examining at least one of a node of the network, data transmission within the network, or data received from a cyber defense mechanism; a generation module configured to generate a cyber-attack based on the at least one vulnerability of the network, and a goal to be achieved by the cyber-attack. The system includes a penetration module configured to penetrate the network with the cyber-attack and determine an effectiveness rating of the penetration; and a feedback module configured to provide a feedback to the identification module based on at least the effectiveness rating of the penetration.

International Classification:

H04L 12/24
G06T 13/80

Abstract:

An exemplary system and method for generating a network diagram. The system includes a first interface for receiving one or more first datasets of network data. A processor configured to generate a first network diagram and identify changes in a network by overlaying one or more network diagram layers or a second network diagram on the first network diagram. The one or more network diagram layers corresponding to captured packets of the first datasets or of second datasets and the second network diagram corresponding to captured packets of the second datasets. A second interface for graphically displaying the network diagram by highlighting and/or animating one or more nodes and/or node connections based on at least one of the identified changes from the overlay.

Abstract:

An electrolytic biosensor for use in intracorporeal leak detection may be incorporated into a surgical drain that is installed post-operatively at the site of a wound. The electrolytic biosensor may be used to monitor drain effluent flowing through the surgical drain by measuring a fluid conductivity of the drain effluent. Certain changes, patterns, or responses of the so measured fluid conductivity values may be indicative of a physiological condition of the wound. For example, when the wound is a gastrointestinal anastomosis, the fluid conductivity values measured with the electrolytic biosensor may be used to characterize a fluid integrity of the gastrointestinal anastomosis. An electrolytic biosensor system may include an application that records conductivity data and provides notifications, such as a patient alarm, when a leak is detected.
