Search for intruders fuels new firewalls
By Michael Moeller

  Internet firewalls are growing beyond prevention to incorporate more proactive security measures.

In addition to providing border security, new software from Trusted Information Systems Inc. and Internet Security Systems Inc. can monitor in real time suspicious network activity.

Also, Authentex Software Corp. and Terisa Systems Inc. have announced products that protect documents at their source.

"With the Internet taking off, the role of security is critical, since the data is no longer contained and transmitted on a private WAN; it is now being done on an open public network," said Jerry Feldenger, security manager for a major New York bank.

Trusted Information Systems, of Glenwood, Calif., next month will ship ForceField, a new technology based on its Gauntlet firewall that enables corporations to protect World Wide Web pages from vandalism.

ForceField modifies the operating system that powers a Web site to close loopholes that hackers might be able to exploit, officials said. ForceField is priced at $495.

TIS also announced last week that its Gauntlet firewall now supports Microsoft Corp.'s Authenticode digital signature technology, enabling users to block access of ActiveX controls or Java applets that have not been signed by a trusted third party using Authenticode.

Atlanta-based Internet Security Systems last week released RealSecure, a real-time intrusion recognition and response tool that monitors network traffic and blocks suspicious activity. It watches source and destination addresses and the types of service requests being made, and monitors a list of more than 50 typical hacking signatures. RealSecure is priced at $4,995.

This week, Authentex, of Massena, N.Y., will release a beta of DataSafe, security software that enables users to store, transmit and retrieve documents securely over intranets or the Internet. Using a combination safe metaphor as its user interface, DataSafe allows users to drag and drop files into the safe to encrypt them. Priced at $79.95, DataSafe is due to ship next month.

For its part, Terisa Systems, of Los Altos, Calif., announced SecureWeb Documents, a digital certificate/digital signature technology that enables specific forms and documents to be signed and sealed when transmitted over the Internet.

SecureWeb Documents, which leverages the underlying technology found in the Secure-HTTP standard, is due by the end of this month with pricing to be set at that point.

On the bundling front, Raptor Systems Inc., of Waltham, Mass., and CyberGuard Corp., of Fort Lauderdale, Fla., each landed deals indicative of the expanding role that firewalls are taking within corporations.

Starting next month, Raptor's Eagle NT firewall will be included within Compaq Computer Corp.'s SmartStart configuration and optimization utility for its servers. SCO and CyberGuard tapped each other last week for a joint-marketing agreement that calls for SCO to resell the CyberGuard firewall.
