RE: Unsecure file permission of ZoneAlarm pro.

["Todd Towles" <toddtowles () brookshires com>]

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.

There is absolutely no security issue here.

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.
