Intrusion Prevention (IPS)
Intrusion Prevention protects your network and assets by inspecting traffic for specified threat characteristics. Threat signatures are collected into collections called IPS Profiles.
When you configure an access rule, you can choose a predefined IPS profile such as Balanced Security and Connectivity or Maximum Security, or create a custom profile using Snort signatures that you choose. You can also choose whether to block or just monitor traffic that matches an IPS profile.
You can specify a default IPS profile on the Rule Defaults page that is automatically selected in each new rule. Default settings apply to both private access rules and internet access rules. See Rule Defaults and See Edit Rule Defaults and Global Settings.
See Manage IPS Profiles.
