About Configuring Sources in Internet Access Rules
The Cisco Secure Access policy is a collection of an organization's internet and private access rules. On internet rules, you can add source and destination components.
Sources on internet rules are either pre-configured or composite components. Source components such as Registered Networks and Network Tunnel Groups acquire and manage the web traffic in your organization.
Composite sources may include an IP address, CIDR block, or wildcard mask.
This guide describes the configuration options for source components on internet Access rules.
