US Patent:

7421576, Sep 2, 2008

Filed:

Jan 16, 2003

Appl. No.:

10/345265

Inventors:

Alexander Dale Kent - Los Alamos NM, US

Assignee:

The United States of America as represented by the United States Department of Energy - Washington DC

International Classification:

H04L 9/00

US Classification:

713155, 713153, 713168, 380277

Abstract:

Methods and systems in a data/computer network for authenticating identifying data transmitted from a client to a server through use of a gateway interface system which are communicately coupled to each other are disclosed. An authentication packet transmitted from a client to a server of the data network is intercepted by the interface, wherein the authentication packet is encrypted with a one-time password for transmission from the client to the server. The one-time password associated with the authentication packet can be verified utilizing a one-time password token system. The authentication packet can then be modified for acceptance by the server, wherein the response packet generated by the server is thereafter intercepted, verified and modified for transmission back to the client in a similar but reverse process.

Appl. No.:

13/826736

Inventors:

Alexander Kent - Los Alamos NM, US

International Classification:

H04L 29/06

US Classification:

726 25

Abstract:

Non-harmful data mimicking computer network attacks may be inserted in a computer network. Anomalous real network connections may be generated between a plurality of computing systems in the network. Data mimicking an attack may also be generated. The generated data may be transmitted between the plurality of computing systems using the real network connections and measured to determine whether an attack is detected.

International Classification:

H04L 29/06
G06N 5/02
G06N 7/00
H04L 1/00

Abstract:

A system, apparatus, computer-readable medium, and computer-implemented method are provided for detecting anomalous behavior in a network. Historical parameters of the network are determined in order to determine normal activity levels. A plurality of paths in the network are enumerated as part of a graph representing the network, where each computing system in the network may be a node in the graph and the sequence of connections between two computing systems may be a directed edge in the graph. A statistical model is applied to the plurality of paths in the graph on a sliding window basis to detect anomalous behavior. Data collected by a Unified Host Collection Agent (“UHCA”) may also be used to detect anomalous behavior.
