Users differ over benefits of Microsoft Patch Guard

Sunday, October 8th, 2006

IT managers have divided views of a simmering dispute between two major security vendors and Windows Vista 032.jpgMicrosoft Corp. over the latter’s Patch Guard technology, which prevents access to the 64-bit Windows kernel.

Security software vendors Symantec Corp. and McAfee Inc. say the Patch Guard technology prevents the use of certain features in third-party tools that would make Windows safer from hackers. McAfee this week took out a full-page advertisement in London’s Financial Times newspaper and charged that Microsoft’s use of Patch Guard is anticompetitive behavior.

Microsoft, meanwhile, contended that the technology itself closes the 64-bit Windows kernel to unauthorized access.

"This is a double-sided sword," said Andreas Wuchner, head of IT security architecture and strategy at Novartis Pharma AG in Basel, Switzerland. "Microsoft got blamed in the past for not being able to [better] protect their customers. Now that they are moving forward, everyone starts blaming them again for being a monopolist."
