Zone Alarm stores its config. files in
%windir%\Internet Logs\* . But strangely,
ZoneAlarm sets the folder/file permission (NTFS) of
%windir%\Internet Logs\* to,
after its first started.
Even If you try to change the permission to...
Administrator (s): full
users: read and execute
[these are the default permissions]
Strangely, the permission again changes back to...
EVERYONE: Full each time
ZoneAlarm Pro (ZAP) is started. I've tested these in
zap 4.x and 5.x
This could prove harmful if we have a malicious
program/user running with
even with a user privilege on the system.
Well a malicious program could modify those config
file in a way ZAP will stop
functioning. This is what ZoneLabs had to say...

yap, true... but shouldnt ZAP have some protection
against such attacks? instead
of leaving the permission to " EVERYONE: Full " I
wonder if a program could bypass
ZAP filters using "safePrograms*.xml"
anyone wanna take this thing to a new level, please go
