Configuring and running LiveUpdate
The LiveUpdate component of the security gateway lets you schedule updates of the definitions and
signatures that are used by the following content security components:
■
Antispam
■
Antivirus
■
Content filtering
■
Dynamic Document Rating (DDR)
■
Intrusion detection and intrusion protection (IDS/IPS)
Note: If you have made changes to pre-configured intrusion detection policies, LiveUpdate may
overwrite those changes.
Configuring LiveUpdate involves the following:
■
Defining a LiveUpdate server
■
LiveUpdating components
■
Optionally, Running LiveUpdate manually
Defining a LiveUpdate server
To update a component, the security gateway contacts the LiveUpdate server you specify for the
component and downloads updated configurations. If you specify more than one LiveUpdate server,
the security gateway contacts the servers in the order in which they are listed.
