International Classification:

G06F 11/00
US Classification:

726 23, 726 22, 726 24, 726 25, 726 26, 713189, 713190, 713191, 713192, 713193, 717174, 717175, 717176, 717177, 717178, 705 51, 705 52, 705 53, 705 54
Abstract:

An intrusion detection system for a computer network includes a knowledge database that contains a baseline of normal host behavior, and a correlation engine that monitors network activity with reference to the knowledge database. The correlation engine accumulating information about anomalous events occurring on the network and then periodically correlating the anomalous events. The correlation engine generates a worm outbreak alarm when a certain number of hosts exhibit a role-reversal behavior.

International Classification:

H04L 9/00
US Classification:

713153000
Abstract:

A security device for a network operates to inspect data packet traffic outgoing from an application server, the data packet traffic including a data packet destined for a client device, the data packet containing a cookie created by the application server. The security device is further operable to extract the cookie from the data packet, encrypt the cookie using a secure key, and then send the encrypted cookie to the client device for storage thereon.

Filed:

Feb 5, 2009
Appl. No.:

12/366630
Inventors:

Srikrishna Kurapati - Richardson TX, US
Rajesh Mohan - Sunnyvale CA, US
Karthikeyan Sadhasivam - Richardson TX, US
Satyam Tyagi - Richardson TX, US
Assignee:

SIPERA SYSTEMS, INC. - Richardson TX
International Classification:

H04L 9/32
G06F 21/00
US Classification:

713168, 726 7
Abstract:

The present invention provides a system, method and apparatus for authenticating calls that is a robust Anti-vishing solution. The present invention can identify Caller ID spoofing, verify dialed number to detect man-in-the middle and verify called party against dialed digits to detect impersonation. This solution can handle calls coming from any phone any where with little impact on user experience. Two separate solutions are tailored for smart phones (communication devices capable of running application software) and traditional phones to reduce the impact to user experience while providing robust verification.
