The Client Validation Sequence Parent topic

OfficeScan client validation refers to the process of evaluating an OfficeScan client’s security posture and returning instructions for the OfficeScan client to perform if the Policy Server considers it to be at-risk. The Policy Server validates an OfficeScan client by using configurable rules and policies.
Below is the sequence of events that occurs when an OfficeScan client attempts to access the network:
  1. The Cisco Network Access Device starts the validation sequence by requesting the security posture of the client when it attempts to access the network.
  2. The Network Access Device then passes the security posture to the ACS server.
  3. The ACS server passes the security posture to the Policy Server, which performs the evaluation.
  4. In a separate process, the Policy Server periodically polls the OfficeScan server for Virus Pattern and Virus Scan Engine version information to keep its data current. It then uses a policy you configure to perform a comparison of this information with the OfficeScan client security posture data.
  5. Following that, the Policy Server creates a posture token, and passes it back to the OfficeScan client.
  6. The OfficeScan client performs the actions configured in the posture token.
