Cisco <strong>IronPort</strong> <strong>AsyncOS</strong> 7.6 for Email <strong>Configuration</strong> <strong>Guide</strong><br />

Chapter 8 Anti-Virus<br />

To perform virus scanning, you must first enable virus scanning on the Cisco <strong>IronPort</strong> appliance. After<br />

you enable the virus scanning engine or engines, you can apply the virus scanning engine to incoming<br />

or outgoing mail policies.<br />

You can enable a virus scanning engine when you run the System Setup Wizard. Or, you can enable and<br />

modify the virus scanning engine global configuration settings via Security Services > Sophos/McAfee<br />

Anti-Virus pages (GUI) or the antivirusconfig command (CLI). You can configure the following<br />

global settings:<br />

Globally enable McAfee or Sophos anti-virus scanning for the entire system.<br />

Specify the anti-virus scanning timeout value.<br />

In addition to the two values on the global settings page, you can further configure the anti-virus settings<br />

via the Service Updates page (available from the Security Services tab). Additional settings include:<br />

How (from which URL) the system will receive anti-virus updates. The virus definitions are updated<br />

from a dynamic URL. If you have strict firewall policies, you may need to configure your Cisco<br />

<strong>IronPort</strong> appliance to obtain updates from a static URL.<br />

How frequently the system checks for new virus definitions. (You define the number of minutes<br />

between checks.)<br />

You can optionally enable a proxy server for obtaining anti-virus updates.<br />

For more information about configuring these additional settings, see Service Updates, page 15-10.<br />

Enabling Anti-Virus Scanning and Configure Global Settings<br />

Step 1 Select Security Services > McAfee.<br />

Or<br />

Select Security Services > Sophos.<br />

Step 2 Click Enable. The license agreement page is displayed.<br />

Note Clicking Enable enables the feature globally for the appliance. However, you must later enable<br />

per-recipient settings in Mail Policies.<br />

Step 3 After reading the agreement, scroll to the bottom of the page and click Accept to accept the agreement.<br />

Step 4 Click Edit Global Settings.<br />

Step 5 Choose a maximum virus scanning timeout value.<br />

Configure a timeout value for the system to stop performing anti-virus scanning on a message. The<br />

default value is 60 seconds.<br />

Step 6 Submit and commit your changes.<br />

Step 7 You can now configure anti-virus settings on a per-recipient basis. See Configuring Virus Scanning<br />

Actions for Users, page 8-8.<br />
