It depends on the nature of a stress, the source of attack. Your statement may be right in the current, mostly peaceful Net, where the threats are generated by the lightly-armed persons (or small groups) only. But it may become wrong when applied to the "warfare" circumstanses, where a threat is engineered by a dedicated institution, which employs highly skilled (not only in CS) personnel and is supported with the resources of the government of some country. > When a >vulnerability is discovered in an open source OS, the code is fixed quickly >and made available to the community more quickly then M$ can respond with a >service pack / patch (If they so desire).

But again, a fix in 2-3 days is good now, but it isn't good enough in "warfare". "Warfare" requirements ask for hours, sometimes even minutes for manual fix, and Open Source development style certainly can't provide that. >BTW: As the web site (www.openbsd.org) says "Three years without a remote >hole in the default install!" is a pretty impressive statement! Here we touch the most valuable factor - "static resistance" against an attack. And exactly here the Open Source operating systems are especially vulnerable in a warfare circumstances -- because they provide enough source data to a skillful and resourceful "cyber warfare institution" (let's call it CWI -;) . Such a CWI may use powerful computers for simulation, employ serious experts in Operations Research etc, and may have few years for engineering an attack. So, I'm not talking about the wild students or even terrorist groups of various kinds.
