Microsoft Gives Windows Vista an A-Plus for Security

Jones stated that Vista has an improved security vulnerability profile over its predecessor, and a significantly better profile relative to comparable modern competitive operating systems. He said that Vista saw one security vulnerability since its launch and that the bug, in the anti-malware scanning engine used by the bundled-with-Vista Windows Defender, was patched last month.

Of course 90 days is a pretty early mark to benchmark the security of the operating system and time will tell if Vista is as secure as Microsoft hopes it is. Some say that hackers are moving away from attacking the core operating systems and are instead focusing on third-party applications and drivers. Son in the future, though it may be likely that Microsoft will be less to blame for attacks because it's invested in [Vista's] security, the overall volume of attacks or exploits will not diminish.
