DETERMINA LAUNCHES MEMORY FIREWALL PROTECTION.

Determina Inc., Redwood City, Calif. Inc. has announced that its patent-pending Memory Firewall product is the only proactive security solution available that can stop mass worm attacks, including Zotob and its variants, before they can execute a single line of malicious code on a vulnerable system. While traditional intrusion prevention systems rely on attack signatures or behavior to protect IT systems, Determina's Memory Firewall is the only product that blocks attacks on known and unknown vulnerabilities before they can compromise enterprise applications and damage servers.

Worms represent a critical threat to enterprise network security. The speed of their propagation can render networks unavailable due to the traffic they generate, and they are often designed to compromise mission-critical information. The threat of directed attackers using Zotob to exploit vulnerabilities and steal confidential data in the enterprise is very real.

"Other security solutions can't block what they don't know to look for, and worms spread far faster than network administrators can update threat signatures or patch their systems," said Nand Mulchandani, VP of Marketing, Determina. "Determina's Memory Firewall protects the vulnerability itself, rather than pattern matching the attack or its behavior. From the moment it's deployed, our customers are always covered against any attack and its variants on a specific vulnerability."

"The Zotob Worm is a troubling example of a worm that has many variants," said Saman Amarasinghe, CTO, Determina and Associate Professor of the Department of Electrical Engineering and Computer Science at MIT. "There have been 11 variants in under two days, and there may be a number of hackers using this vulnerability to compromise systems. Determina's customers are immune to all of these, because the Memory Firewall is the only endpoint security technology that proactively blocks mass worm attacks at their point of entry, without the need for any signatures, policies, or behavioral training. No other solution, including signature-based security systems, can proactively protect against these attacks."

About the Determina Memory Firewall

Determina's Memory Firewall technology is the result of years of groundbreaking research in computer science at M.I.T. and in corporate labs. Using software emulation and compiler principles, the Memory Firewall runs on enterprise networks and forms a protective shield around software programs and applications while they are running in computer memory. It allows normal program code to run as it should, but prevents malicious code from executing. The Memory Firewall offers clear benefits to enterprises that want to eliminate the threat posed by worms:

-- Protection: The Memory Firewall is able to categorically stop the entire class of memory-based attacks. Memory-based vulnerabilities represent by far the largest and most dangerous class of critical Windows flaws.

-- Accuracy: The unique approach taken by the Memory Firewall makes it extremely accurate at stopping both known and unknown attacks.

-- Manageability: The Memory Firewall requires no ongoing maintenance to be effective. It deploys on a server in minutes and doesn't require training, tuning, or signature updates -- ever. Its advanced enterprise management capabilities allow administrators to centrally manage Memory Firewall deployments and generate detailed reports on threats found and thwarted.
