If your scheduled update is for a time that coincides with a busy period, you may not be getting your updates as regularly as anticipated. I recommend having a backup system, such as the old-fashioned dial-up access for retrieving updates.

Not only does it provide a level of redundancy, it can also act as a safety check regarding a signature update. On more than one occasion, the vendor of the antivirus software we use released a buggy update, and I was able to validate this by comparing the results of the files obtained via FTP with those downloaded from dial-up access. Testing Having successfully obtained that latest signature update, you should test it before general deployment throughout your organization. In our company, I have a list of key systems that get a copy of the latest signature version in advance of other clients.

These preview systems contain a cross sample of operating systems and critical applications so that they are representative of our general PC population. The key systems are configured to pick up their updates from a private location unbeknownst to everybody else. Provided there are no glaring problems, a mass rollout of the signature update will follow within 48 hours.

The general rollout is automatically performed unless manually overridden. Obviously, with the frequency of updates coming out, testing is much less exhaustive than a normal software deployment. You can increase the time used to test, but the trade-off is that clients are then further delayed in receiving an update, which can prove to be a dangerous situation. In certain circumstances, such as with the recent SirCam virus, we have eliminated the testing phase in favor of a more rapid deployment of the signature files.

In either case, you should have some flexibility built into your process. Deployment Deployment is clearly the most crucial phase. This would simply saturate your available bandwidth and introduce unnecessary delays for clients. We have set up our system so that clients always pick up their updates from a server that is local to them. In the background, a master server distributes the tested update to various distribution servers.
