New patents for Web and messaging gateway security

Secure Computing Corporation announced that it has been awarded three new patents for systems and methods to enhance electronic communications security. The patents — two awarded by the US Patent and Trademark Office and the third by the Patent and Trademark Office of Germany — complement Secure Computing’s extensive patent portfolio, which covers a broad scope of Internet infrastructure security and performance technologies.

The Patents Issued:

– U.S. Patent No. 7,089,590 – “Systems and Methods for Adaptive Interrogation Through Multiple Queues.”

This new technology, currently deployed in Secure Computing’s IronMail(R) messaging gateway security appliance, organizes and prioritizes message handling to get optimal performance while maintaining the high level of security inspection. This provides state-of-the-art efficiency in processing inbound and outbound messages to ensure that unwanted and malicious content is swiftly blocked and outbound sensitive information is restricted. This technology enables Secure Computing IronMail appliances to effectively protect large organizations with a high volume of email traffic.

– U.S. Patent No. 7,124,438 – “Systems and Methods for Anomaly Detection in Patterns of Monitored Communications.”

This technology, also utilized by IronMail, makes it possible to detect anomalies in the behavior of messaging traffic, thereby protecting against undocumented threats. Anomaly detection is an essential technology to effectively block previously undetected or undocumented threats for which a signature or pattern does not exist. It combines historic data with global and local traffic trends to proactively detect attacks such as Distributed Denial of Service (DDoS) attacks. Using this technology, Secure Computing’s IronMail appliances are able to immediately block or quarantine suspect email that could constitute a new unknown threat.

– German Patent No. 102005050047 – “Method, Arrangement, and Safety Gateway for Secure Authentication and Data Transfer Between two Data Processing Units via at Least One Network.”

This technology significantly improves the manageability and security of SSL traffic. It secures vulnerable communications between entities over the Internet, encrypting data and blocking malicious content. Deployed as part of Secure Computing’s Webwasher solution, it inspects encrypted web traffic without losing the strong authentication between client and server.
