Policy Server for NAC Deployment Parent topic

The following procedures are for reference only and may be subject to change depending on updates to either the Microsoft and/or Cisco interfaces.
Before performing any of the tasks, verify that the Network Access Device(s) on the network are able to support Cisco NAC (see Supported Platforms and Requirements). See the device documentation for set up and configuration instructions. Also, install the ACS server on the network. See the Cisco Secure ACS documentation for instructions.
  1. Install the OfficeScan server on the network (see the Installation and Upgrade Guide).
  2. Install the OfficeScan client program on all clients whose antivirus protection you want Policy Server to evaluate.
  3. Enroll the Cisco Secure ACS server. Establish a trusted relationship between the ACS server and a Certificate Authority (CA) server by having the ACS server issue a certificate signing request. Then save the CA-signed certificate (called the ACS certificate) on the ACS server (see Cisco Secure ACS Server Enrolment for details).
  4. Export the CA certificate to the ACS server and store a copy on the OfficeScan server. This step is only necessary if you have not deployed a certificate to clients and the ACS server (see CA Certificate Installation).
  5. Deploy the Cisco Trust Agent and the CA certificate to all OfficeScan clients so clients can submit security posture information to the Policy server (see Cisco Trust Agent Deployment).
  6. Install the Policy Server for Cisco NAC to handle requests from the ACS server (see Policy Server for Cisco NAC Installation).
  7. Export an SSL certificate from the Policy Server to the Cisco ACS server to establish secure SSL communications between the two servers (see Policy Server for Cisco NAC Installation).
  8. Configure the ACS server to forward posture validation requests to the Policy Server (see ACS Server Configuration).
  9. Configure the Policy Server for NAC. Create and modify Policy Server rules and policies to enforce your organization’s security strategy for OfficeScan clients (see Policy Server for Cisco NAC Configuration).
