    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.
