''When a patch is released at 9 a.m., you need to have it installed in all your machines by 9:05,'' Bayles says. ''Doing this manually is impossible.''
Bayles says automation is the only answer for today's security patch needs. ''We used to live in a little private network where we enjoyed a level of control,'' she says. ''Now, my users need access to the Internet from any desktop and I want them to be able to do that for a productive business.''
But she knows openness has its drawbacks.
Bayles is not alone in her dilemma.
IT administrators and techies are being worn down from the almost daily barrage of patches and updates deployed for critical enterprise software. The flood often forces managers to pull IT workers off other projects to handle the load, diverting attention and scarce budget dollars to managing, testing and distributing patches.
To alleviate the pain of going desktop-to-desktop for 500 users, Bayles employs tools that distribute critical software updates automatically via a desktop agent.
Audrey Rasmussen, vice president at Enterprise Management Associates in Boulder, Colo., says the combination of increased patches and more remote access to corporate networks is forcing IT managers to consider automated patch management and software distribution tools. In fact, a cross-section of companies, such as HP (with its Novadigm purchase), iPass, Symantec, Altiris, Marimba, Novell and a slew of others, are all making a play for the automated software distribution market.
''It's a hot area right now,'' says Rasmussen. ''The frequency of patches and the risk of exposure poor security brings companies, as well as the volume of systems to patch -- servers and desktops -- can be horrendous.''
Patches, she says, sometimes come out as frequently as every day. ''If it's just a program bug, IT managers can live with the current version for a bit, but when it's a security patch that can open them up to attack, they need to get it quickly and efficiently across the enterprise,'' says Rasmussen.
For James Payne, the advent of automated tools is a godsend. Payne, an end user support supervisor at Roto-Rooter in Cincinnati, Ohio, used to spend his time after a patch was announced burning CDs to quickly distribute to the company's 60 locations. ''Someone at the site would have to walk around and do the installs. Half the computers never got the update,'' he says. ''It was cumbersome.''
Payne also says the manual approach wreaked havoc with the network.
''There were viruses that would take advantage of a hole in Windows because a patch wasn't applied correctly or was missed during the manual install,'' he says. ''We never really had an on-site guru at other locations... so we would have to spend time fixing [problems].''
Most software distribution tools feature an auditor that lets IT managers know whether a computer has received the latest patches and updates. If the computer is not up-to-date, it can be blocked from accessing the network.
Rasmussen says it's critical for IT managers to make sure they still leave room for testing the patches. ''This is the bottleneck for totally automating patch management,'' she says. ''IT managers need to test patches on different platforms and different configurations they might have. They need to design a process for doing that efficiently.''
Joel Snyder, senior partner at Opus One, a consulting and information technology firm in Tucson, Ariz., agrees.
''It's difficult to keep up with updates because of the quality assurance problem,'' he says. ''But every time you push something out, it's going to break something else. This problem is magnified with remote access, but that doesn't mean you stop trying. You just have to invest the time to make the patches work.''
Al Stern, director of systems architecture at the University of Dayton in Ohio, has a multi-step approach to vetting patches. Stern and his team have what they call a ''critical patch committee''.
The committee, a group within IT, reviews Microsoft patches on their release date. They then push the approved patches to a group of 100 test users, Stern says. The goal is to see if that test group notices any serious problems. If nobody is ''detonated'', then the patch is pushed to the rest of the campus' 12,000 users within days. Virus updates and critical patches are on a much quicker schedule, being tested every hour and then dispatched. ''That process never stops,'' he says.
Although the university has an e-mail list used to announce all viruses and remedies to students, Stern says he relies on the automated tools. ''We can't take the chance that they might not read the e-mail, or see it's from the PC Help Desk and ignore it,'' he says. ''That's tremendously ineffective.''
Stern cautions his peers to be careful with the length of automated updates, though. ''If it's more than 20 seconds to scan and update the PC, users complain,'' he says. ''You have to be fast.''
Tasty Baking's Bayles says if the update is going to take a while, she prefers to let users know ahead of time. ''I wouldn't want to disrupt somebody's workday.''
