Signature Updates; Updating Snapservers With Internet Access - Overland Storage SnapServer Administrator's Manual

SnapServer 7.0 Administrator's Guide

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
FTP
UNC
Local Path

Updating SnapServers with Internet Access

If your SnapServers have direct access to the Internet, you only need to schedule the
downloads to set up automatic signature updates. If access to the Internet is routed through
a proxy server, you may also need to specify the name of the proxy server. Both procedures
are explained below:
To Schedule Signature Update Downloads
1. Choose Scanner > Signature Update Options .
2. On the Schedule tab, click Enable Scheduled Download. Select the initial download date
and time, then select how often to repeat the download.
3. Click OK.
To Specify a Proxy Server
1. Navigate to Scanner > Signature Update Options , and click the Incoming tab.

Description
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.
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/SMB) 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.
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 (for
example,
/shares/SHARE1/virusdefs).
Note that the path to the share is case-sensitive.
