The Cisco ISE must have a posture policy for posture required clients defined in the NAC System Security Plan (SSP). This is required for compliance with C2C Step 2.

Description
Posture assessments can reduce the risk that clients impose on networks. The posture policy is the function that can link requirements to applicable clients. Multiple requirements can be associated with a single policy. However, multiple polices can also be applicable to the same client. The posture policy operates in such a way that all applicable policies are applied, versus the top-down first match approach.
