Worm after worm changed the face of internet security in Win2k's first 2 years. Five years down the line the battle is far from won, but the improvements are dramatic." From the article: "Things were different in the year 2000. Programmers felt vindicated that the Y2K bug didn't turn out to be that big of a deal. We made it past January 1st, and then it was time to move on. Windows 2000 came out that first quarter, just as security was becoming more interesting to more people -- and Windows was a good place to start. It was also seemed to be the start of a new breed of Windows hackers."
