Configuring IDS Policies
An IDS Policy is configured using two tables with "parent-child" type relationship:
■ IDS Policies table ("parent"): Defines a name and provides a description for the IDS Policy.
You can configure up to 20 IDS Policies.
■ IDS Rules table ("child"): Defines the actual rules for the IDS Policy. Each IDS Policy can
be configured with up to 20 rules.
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
● You can edit and delete the default IDS Policies.
● If the IDS Policies table is empty (i.e., you have deleted all IDS Policies) and you
want to return the default IDS Policies, disable IDS and then enable it again.
The following procedure describes how to configure IDS Policies through the Web interface. You
can also configure it through ini file or CLI:
■ IDS Policy table: IDSPolicy (ini file) or configure voip > ids policy (CLI)
■ IDS Rules table: IDSRule (ini file) or configure voip > ids rule (CLI)
