ZoneAlarm
The ZoneAlarm Pro section of access control allows for the blocking of local hosts which
aren't running ZoneAlarm Pro software or which aren't running a sufficiently recent
version of ZoneAlarm Pro software. ZoneAlarm Pro provides a measure of protection
against malware for hosts and being able to allow Internet access based on this
protection being present and operational can be useful.
The Enable ZoneAlarm Pro support checkbox specifies if the ZoneAlarm Pro
enforcement section of access control is active or not. Turning this feature on does
involve a small sacrifice in the performance of this unit.
The ZoneAlarm Hosts menu allows selection of the hosts which must be running
ZoneAlarm Pro software to be able to access the Internet.
The Check frequently checkbox indicates if local hosts should be queried as to their
ZoneAlarm Pro status and version very often or less often. Turning this on involves a
small sacrifice in the performance of this unit and a slight increase in network activity.
The ZoneAlarm licence key must contain a valid ZoneAlarm Pro licence or this section
of access control is inoperative. Licences are available from ZoneLabs.
