Smart Partner: Hackers Breach Firewall-1

(Other stories by David Raikow)

"While Checkpoint issues service pack to address vulnerabilities, hackers warn against placing too much faith in firewalls."

"An audience of several hundred network security professionals watched with rapt attention last week as a trio of hackers repeatedly penetrated one of the industry's most trusted and popular firewall products--Checkpoint Software's Firewall-1. The demonstration, presented at the "Black Hat" security conference in Las Vegas, challenged the widely accepted notion that firewalls are largely immune to direct attack."

"The panel--John McDonald and Thomas Lopatic of German security firm Data Protect GmbH and Dug Song of the University of Michigan--identified three general categories of firewall attacks. They began by demonstrating a number of relatively simple techniques by which an attacker could impersonate an authorized administrator, and thus gain access to the firewall application itself. A second type of attack tricked the firewall into believing an unauthorized Internet connection was actually an authorized virtual private network connection. Finally, the panel exploited a number of errors in the process used to examine traffic passing through the firewall to sneak in dangerous commands."
