Applying IDS/IPS policies
IDS/IPS policies can be applied to any of the following:
■
VPN policies
■
Clientless VPN connections
■
Forward filters
■
Web VPN connections
■
Port forwarders
■
Network interfaces
Applying an IDS/IPS policy to any of these components provides protection against malicious traffic
passing through the security gateway. By default, no IDS/IPS policies are applied to the security
gateway components.
For information on how to apply IDS/IPS policies to any of the security gateway components, see the

Applying IDS/IPS policies to VPN policies
VPN policies are applied to secure IPsec tunnels to ensure the integrity and security of data being
passed through a tunnel. Applying an IDS/IPS policy to a VPN policy provides detection and
prevention of malicious traffic from entering the secure IPsec tunnels.
