Synchronization<br />

Using Policy Server for Cisco NAC<br />

Regularly synchronize the Policy Server with registered <strong>OfficeScan</strong> servers to keep the<br />

Policy Server versions of the Virus Pattern, Virus Scan Engine, and server outbreak<br />

status (normal mode or outbreak mode) up-to-date with those on the <strong>OfficeScan</strong> server.<br />

Use the following methods to perform synchronization:<br />

• Manually: Perform synchronization at any time on the Summary screen (see<br />

Summary Information for a Policy Server on page 15-39).<br />

• By schedule: Set a synchronization schedule (see Administrative Tasks on page<br />

15-42).<br />

Certificates<br />

Cisco NAC technology uses the following digital certificates to establish successful<br />

communication between various components:<br />

TABLE 15-5. Cisco NAC Certificates<br />

CERTIFICATE DESCRIPTION<br />

ACS<br />

certificate<br />

Establishes trusted communication between the ACS server<br />

and the Certificate Authority (CA) server. The Certificate<br />

Authority server signs the ACS certificate before you save it<br />

on the ACS server.<br />

CA certificate Authenticates <strong>OfficeScan</strong> clients with the Cisco ACS server.<br />

The <strong>OfficeScan</strong> server deploys the CA certificate to both the<br />

ACS server and to <strong>OfficeScan</strong> clients (packaged with the<br />

Cisco Trust Agent).<br />

Policy Server<br />

SSL<br />

certificate<br />

Establishes secure HTTPS communication between the Policy<br />

Server and ACS server. The Policy Server installer<br />

automatically generates the Policy Server SSL certificate<br />

during Policy Server installation.<br />

The Policy Server SSL certificate is optional. However, use it<br />

to ensure that only encrypted data transmits between the<br />

Policy Server and ACS server.<br />
