In August 2004, Microsoft released Microsoft XP Service Pack 2 (SP2). This marked a significant date in the network security world. The largest software provider in the world had released a version of their operating system (OS) that had built in security turned on by default. The next several weeks and months were interesting as many dependant software applications "broke" when the security features were tightened up. But all things said and done, it was a great milestone in security, and although it was a rough road, it was a long time in coming.
