One of the ways
the
OfficeScan client determines
which policy or profile to use is by checking its connection status
with the
OfficeScan server. If
an internal
OfficeScan client (or
a client within the
corporate network) cannot connect to the server, the
client status becomes offline. The
client then applies a policy
or profile intended for external
clients.
Reference servers address this issue.
An OfficeScan client that
loses connection with the OfficeScan server
will try connecting to reference servers. If the client successfully establishes
connection with a reference server, it applies the policy or profile
for internal clients.
Policies and profiles managed by reference servers include:
-
Firewall profiles
-
Web reputation policies
-
Data Protection policies
-
Device Control policies
Take note of the following:
-
Assign computers with server capabilities, such as a
web server, SQL server, or FTP server, as reference servers. You
can specify a maximum of 32 reference servers.
-
OfficeScan clients connect
to the first reference server on the reference server list. If connection
cannot be established, the client tries
connecting to the next server on the list.
-
OfficeScan clients use
reference servers when determining the antivirus (Behavior Monitoring,
Device Control, firewall profiles, the web reputation policy) or
Data Protection settings to use. Reference servers do not manage clients or deploy
updates and client settings. The OfficeScan server performs these
tasks.
-
An OfficeScan client cannot
send logs to reference servers or use them as update sources
