Figure 14-2: Enabling IDS on IDS Global Parameters Page
2. From the 'Intrusion Detection System' drop-down list, select Enable.

effect.
14.3.2 Configuring IDS Policies
Configuring IDS Policies is a two-stage process that includes the following tables:
1. IDS Policy (parent table): Defines a name and description for the IDS Policy. You
can configure up to 20 IDS Policies.
2. IDS Rules table (child table): Defines the actual rules for the IDS Policy. Each IDS
Policy can be configured with up to 20 rules.
Note: A maximum of 100 IDS rules can be configured (regardless of how many rules
are assigned to each policy).
The device provides the following pre-configured IDS Policies that can be used in your
deployment (if they meet your requirements):
"DEFAULT_FEU": IDS Policy for far-end users in the WAN
"DEFAULT_PROXY": IDS Policy for proxy server
"DEFAULT_GLOBAL": IDS Policy with global thresholds
These default IDS Policies are read-only and cannot be modified.
To configure an IDS Policy:
1. Open the IDS Policy table (Configuration tab > VoIP menu > Security > Intrusion
Detection and Prevention > Policy Table); the table shows the pre-configured IDS
policies:
