"...statistics gathered by leading security company SecurityFocus on their NTBugTraq site say differently..."
Note that part of their site name is "NT". How impartial do you think that makes them. In fact, I follow their postings regularly, along with those of several other security sites. The one thing that I have noticed about NTBugTraq is that when there are several interrelated bugs in Microsloth Windows based OS's, they almost always bundle them together as only one event, but in similar situations, on non-Microsloth products, they always create separate incidents. That's the kind of diddling with the numbers that it takes to make Microsloth even appear to be somewhat secure. But, the picture is quite different, when viewed from the trenches.
I have run entire IT departments for very large corporations and have been a US security lead for a major oil company and in all those years, two things have become obvious. First, it not only takes significantly more security support staff to secure and keep secure Microsloth based systems, than any UNIX based systems, including LINUX, but the Microsloth security staff has to be much better trained than their UNIX counterparts. Secondly, even with that larger and better trained support staff, the few successful attacks that we experienced were almost exclusively on Microsloth based systems. At one company, we had one MCSE and two MCSE/MCSA's, who were all security specialists and who did nothing else. Those three highly trained specialists maintained security on one fifth as many servers as our single UNIX security man did and he had only a high school diploma and some practical experience and handled system admin work on several of those UNIX systems, as well. While I was there, we never had a single successful attack on a UNIX (or LINUX) based system, while successful NT attacks, though not common, were far from rare. And that's not even considering the Windows desktop attacks and the additional security staff that we had to deal with those problems.
I am now the Infrastructure Director of a new international natural resources exploration and development company. Some time back, we decided that all of our servers will be UNIX (or LINUX) based and our desktops and laptops will all be Macs (UNIX under the hood). Since we began operating in this environment, we have not had a single security event of any kind. I wonder how many companies can say the same of their Microsloth based networks.
Better watch out, Action. Bush hates Macintoshes even more than Linux!
