Chapter 7: Network worms
The excessive centralization trend in IT that was dominant in recent years shoudle be viewed under the angle of network worms attack. Recent concentration of key elements of IT infrastrcture in one (major) datacenter makes such a datacenter perfect target for work attack.
For example centralization of Lotus Notes as a corporate mail platform makes infrastructure more vulnerable to any problem that creates a network congestion like network worms (or other disruption of links between major hubs).
The utopia of creating a "universal PC image" should probably be abolished. The problem with a standard corporate image is that it replicates flows very effectivly and taking into account private parching mechanism that many deploy it is a step to a problem. In all cases that I know patching quality was inferiour to simple application of Microsoft automatic patch policy.
For example secondary infection with Bozori by corporations who previously had suffered from Zotob, demonstrated that despite high visibility and additional management efforts for the initial worm, there were enough unpatched PCs for this new strain to infect initial set of PC to create a critical mass that was enough to propagate it to all major sites: Bozori was not limited to one site.
In a sense the patching that was performed for Zotob was the best possible with the current technology and the results suggest that the technology used was completely outdated and inadequate.
If the first wave of the worm were destructive (like Chernobyl virus of few years ago was), the results for any large corporation would be pretty grim. It's pure luck that all network worms that we encountered were essentially a training exercise for IT staff (or proof of the concept, if you wish), not a real threat.
None of them was explicitly designed to cause damage. So the main negative effects the past were mainly due to panic and overreaction. which are amplified via centralization as one panicked idiot at central site can do more damage than any number of works in 10 years.
But in the future things might change. They are already changing in Middle East. Unfortunately a possibility that in the future a worm can be released by a terrorist group with the explicit aim to damage as many corporate PCs as possible can not be completely discounted.
Unless patching technology is dramatically improved and some more or less modern technology implemented, large corporation that entertain illusion that they pricy package for applying patches works are highly vulnerable to any new network worm that uses any future remotely exploitable Microsoft patch within a couple of weeks from its release. People on all levels of IT management should clearly understand this fact.
One simple solution would be a switch to using Microsoft update site for up to 80% of PCs (users can enter this list voluntarily; some already did :-) or implementing an internal automatic update site. I think that in any large corporation that are less then 20% of PCs that are really "special" in a sense that they can be negatively affected by "blind" Microsoft updates.
