Signature Updates

Chapter 9 CA eTrust Antivirus Software 131

Signature Updates

Signature updates contain the latest versions of the signature files that recognize the

latest infections. They also contain the latest engine versions, which do the work of

looking for infections. Signature updates are made available on a regular basis by

Computer Associates.

These updates are cumulative, so they contain everything from all previous file

updates, plus the newest information on the latest infections. If you have missed a

recent update, you only need to collect the latest signature file to have the most up-

to-date protection.

SnapServers are preconfigured to download signature updates from the CA FTP

site at ftp://ftpav.ca.com/pub/inoculan/scaneng

. By default, no signature updates

are scheduled. The antivirus software will, however, check for signature updates

whenever the server is powered on. To update SnapServers that do not have

Internet access, the following methods are available:

Method Description

FTP Use FTP to download the update files from the Computer Associates FTP site.

You can also use FTP to distribute signature updates from one SnapServer (or

any FTP server) to another.

Note When using FTP, the user name and password are passed as clear

text.

UNC Use UNC to distribute signature updates from one SnapServer to another (or

from any arbitrary SMB or Windows server). Note that for UNC to work, you

must have the Enable Guest Account option enabled

(Network > Windows)

on the SnapServer on which the signature updates reside.

Note Alternatively, you can distribute updates to SnapServers from any

Windows/SMB server. If using this method, make sure the guest account on

the chosen server exists, is enabled, and has a blank password.

Local Path As part of the procedure to provide signature updates to the SnapServer with

no Internet access, you can connect to a local path relative to the root (e.g.,

/shares/SHARE1/virusdefs).

Note that the path to the share is case sensitive.
