Signature Updates
Chapter 9 CA eTrust Antivirus Software

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.
