Intrusion Defense Firewall 1.2 User's Guide - Trend Micro? Online ...

Computers
The Computers screen allows you to manage and monitor the Computers on your network. This screen
updates itself periodically.
Synchronize with OfficeScan
Synchronizes the list of Computers with those managed by OfficeScan. (The list is synchronized
automatically every time you start the Server Plug-in, but it will not be updated if Computers are added to
OfficeScan while the Server Plug-in is running. Use this button to force a synchronization with OfficeScan
while the Server Plug-in is running.)
When the OfficeScan Client is installed on a Computer, the OfficeScan Server assigns it a unique
identification number. It is this unique identification number that OfficeScan and Intrusion Defense
Firewall use to keep track of individual Computers. If the OfficeScan Client is uninstalled from a
Computer and then reinstalled (with the Intrusion Defense Firewall Client Plug-in), OfficeScan will
assign the Computer a new Unique ID. The next time you synchronize with OfficeScan to update the
list of Computers, Intrusion Defense Firewall will see the new unique identification number and treat
the Computer as a new entry. Because the Computer's hostname will not have changed, the new
listing for the Computer will append "_1" (or "_2", or "_3", and so on) to the end of the hostname. You
will now have the same Computer listed twice: once as "hostname" and again as "hostname_1". You
should delete the first listing ("hostname") and keep the second ("hostname_1"). (You can rename
"hostname_1" back to "hostname" after deleting the original listing.)
Scan Computers for Open Ports
Scan Computers performs a port scan on all selected Computers and checks the Client Plug-in installed
on the Computer to determine whether its state is either "Client Plug-in Deactivate Required", "Client
Plug-in Activate Required", "Client Plug-in Reactivate Required", or "Online". (The scan operation, by
default, scans ports 1-1024. This range can be changed in the System > System Settings section under
the Scan tab.)
Port 4118 is always scanned regardless of port range settings. It is the port on the Computer to
which Server Plug-in initiated communications are sent. If communication direction is set to "Client
Plug-in Initiated" for a Computer (Computer Details > System > Settings > Computer >
Communication Direction), port 4118 is closed.
Scan Computers for Recommendations
Scan for Recommendations causes the IDF Server Plug-in to scan the Computer and then make
recommendations for Security Rules based on what is detected. The results of a recommendation scan can
be seen in the Computer's Details window on the various Rules screens. See the help for the Computer
Details screen for more information.
Assign a Security Profile to a Computer
This opens a window with a drop-down list allowing you to assign a Security Profile to the Computer. The
name of the Security Profile assigned to the Computer will appear in the Security Profile column in the
Computers list.
