Fort Hood Selects Intrusion to Secure World's Largest U.S. Army Post.

RICHARDSON, Texas -- SecureNet and SpySnare Deployed to Prevent Hackers, Viruses and Spyware from Disrupting Army IT Operations

Intrusion Inc. (Nasdaq:INTZ), ("Intrusion") announced today its selection by the U.S. Army Directorate of Information Management (DOIM) located at Fort Hood for deployment of the SecureNet intrusion detection/prevention system and SpySnare spyware prevention system. Intrusion received an order for approximately $800,000 for the first phase of the project and the order was shipped in December 2004.

Intrusion's SecureNet system detects and blocks unauthorized network intrusions. The Ft. Hood SecureNet installation addresses the common "insider threat" behind the site's perimeter firewall where many of the greatest potential vulnerabilities exist. SecureNet sensors are deployed lower into the site's network, at the department level, and thus, increase threat visibility across the full Ft. Hood network. "We're taking a proactive stance to make ourselves better and more relevant in our information warfare and cyber security mission," explained Lieutenant Colonel Ed Morris, director of the Ft. Hood DOIM. "With the SecureNet deployment at Ft. Hood, we are able to get specific details about whom we're fighting and from where they came. Once we get the enemy in our sights, we're able to take aim and eliminate the offender."

Intrusion's SpySnare spyware prevention system was also selected by Ft. Hood for deployment at the site's network perimeter. SpySnare detects and blocks in-bound and out-bound spyware infections and unauthorized peer-to-peer (p2p) communications, a common source of spyware infections, at the Ft. Hood site. "These spyware programs started out originally as just a nuisance to our users, but today, they're beginning to impact the reliability of our systems and have even broader implications related to the security of our data," explained Major Bert Belisch, 114th Signal Battalion operations and planning officer. "Now that we added the Intrusion SpySnare sensor at the firewall, we're able to spot and block unauthorized p2p sessions, file transfers and spyware infections across the entire site."

Most spyware programs are independent executable files that take on the authorization abilities of the victim's computer. They include auto-install and auto-update capabilities and can report on any attempts to remove or modify them. According to Microsoft, spyware is responsible for half of all PC crashes, (InformationWeek, April 26, 2004). Unlike spyware removal applications that reside on individual desktops and are designed to remove the spyware program after the system has been infected, Intrusion SpySnare prevents spyware programs from being inserted on customer computers by blocking them at the customer's perimeter. SpySnare utilizes Intrusion's high-performance low-latency network analysis engine to implement critical deep-packet inspections in order to determine if spyware signatures are attempting to get into the customer's network. By using specific signatures for known spyware, SpySnare provides real-time awareness of network traffic, delivering unsurpassed intelligence and removing much of the guesswork involved in establishing the necessary network defenses and preventing spyware infections. Once SpySnare detects a spyware signature match, it instantly flags and drops the spyware traffic and alerts the administrator.

Along with the new SecureNet and SpySnare deployments, Fort Hood is implementing Intrusion's innovative Security Status Review (SSR) program. Co-developed with the U.S. Army, SSR leverages Intrusion's powerful SecureNet Provider forensics and real-time display tools, to enable DOIM IA staff to proactively document important security trends which allows DOIM leadership to make critical IT policy and procedure decisions. Also, Intrusion's SSR tools, in combination with SecureNet Provider, helps guide and document "under attack" incident response measures to allow Army personnel to repel attacks in real-time.

"Intrusion engineers worked closely with the entire Ft. Hood DOIM staff to optimize the right solutions for this vital national defense initiative," explained Ben A. Bittle, Intrusion Inc. Director of Product Management. "We're pleased they had the confidence in us and our SecureNet and SpySnare solutions to help defend this important Army site from Cyber-attacks."
