Add Internal Network Resources
An Internal Network resource represents a private address space of IP addresses. Internal networks are managed by your organization and are non-routable or RFC1918 compliant. You must configure an Internal Network resource with either a Cisco Secure Access Site, Registered Network, or Network Tunnel Group. The associated Site, Networks, or Network tunnel groups forward DNS traffic from devices on your organization's internal network to Secure Access.
To start protecting an internal network, add an Internal Network resource to Secure Access. Once added, you can apply an existing policy rule to the internal network resource or add a new rule to protect the resource. Build rules to extend Secure Access's protection to any device that connects to the internet from behind the internal network. For more information about Secure Access policy rules, see Manage the Access Policy.
In Secure Access, all traffic originating from the IP of the site, network, or network tunnel group resource is identified as coming from the Internal Network. The private IP space or IP range defines the scope of the resource. The traffic sent from user devices on your organization's Internal Network is visible in the Secure Access Activity Search report.
