Full Antivirus Pattern Update Configuration Overview

Before you begin, there are several prerequisites that must be met in order to perform a successful pattern database update:

• You must have a valid antivirus scanner license.
• You must have network connectivity and access to the pattern database server.
• Your DNS settings and port settings (port 80) must be correct.

To update the patterns for the antivirus signature database:

1. On the security device, specify the URL address of the pattern-update server.
2. (Optional) Specify how often the device should automatically check for pattern-server updates.

After the security device downloads the server-initialization file, the device checks that the pattern file is valid. The device then parses the file to obtain information about it, including the file version, size, and location of the pattern file server.

If the pattern file on the security device is out-of-date (or nonexistent because this is the first time you are loading it), and, if the antivirus pattern-update service subscription is still valid, the device automatically retrieves an updated pattern file from the pattern file server.
