Best practices
The following sections outline some suggestions for how to employ iDAT
downloads in your updating strategy.
Three-stage updating
If you need to roll out new virus definitions to multiple workstations on your
network, Dr Solomon’s Software recommends a three-stage update strategy
thatwill saveyouexternalnetworkbandwidth,minimize yoursecurityrisks,
and give you more control over your internal updating strategy:
1. If the .DAT files installed onyour network computers are veryold, usea
web browser or FTP client software to download a full .DAT file update
or the SuperDAT utility to a central server on your network, then
configure the AutoUpdate copies on your network computers to
downloadand installthecomplete .DAT setandthecurrent scanengine.
This brings your network to a workable baseline state. You can then
download and install iDAT files to keep current.
2. From the baseline state, use a web browser or FTP client software each
week to download new .UPD files directly from the Dr Solomon’s
Software FTP site to a central server on your network.
If you start from the baseline state described in Step 1,youcansimply
download the most recent .UPD file posted on the Dr Solomon’s
SoftwareFTP site. Ifyouhavenotupdatedinacoupleof weeks,openthe
DELTA.INI file online, and look at the entries in the Multiple Patch and
the Incremental Resolver tables to see which .UPD files you must
download to update the .DAT files installed on your network, then
download each of the files you need, including the DELTA.INI file.
