Sorry John, I was confused between "Failing Closed" and "Failing Open". If integrity checks fail, no traffic is passed. That is better than Microsoft's simple reg disable hack.

ZoneAlarm does not rely on file permissions to protect any configuration files. Configuration files are protected by our TrueVector(r) driver in the kernel. In addition to protecting configuration files against unauthorized changes, there are additional integrity checks and other protection mechanisms implemented for all policy configuration files. Should any policy configuration files fail integrity checks, the firewall will fail closed. Again, no issue. - -- John LaCour Security Services Group Manager Zone Labs LLC, A Check Point Company > From: bipin gautam [mailto:[EMAIL PROTECTED] > Sent: Thursday, August 19, 2004 7:51 PM > To: [EMAIL PROTECTED] > Subject: [Full-Disclosure] Unsecure file permission of ZoneAlarm pro. > > > Hello list, > > Zone Alarm stores its config. files in %windir%\Internet Logs\* .
