For endpoints that require automated remediation, Forescout must be configured to logically separate endpoints from the trusted network traffic during remediation. This is required for compliance with C2C Step 4.

Automated and manual procedures for remediation for critical security updates will be managed differently. Continuing to assess and remediate endpoints with risks that could endanger the network could impact network usage for all users. This isolation prevents traffic from flowing with traffic from endpoints that have been fully assessed and authorized.

This requirement does not mandate a remediation network be used, but rather requires that it be secured where used. For example, unauthenticated devices must not be allowed to connect to remediation networks.

Many sites block unauthorized traffic directly using the Forescout. Forescout accepts only endpoints with IP addresses that are in range. Configure Forescout to identify the endpoint. By default, the IP address is used as the endpoint identifier. The system can be configured to capture the following other endpoint unique identifiers if approved for use by the SSP as the identification method: BIOS Serial number and other hardcoded attributes, OS host name, etc.
