Symantec and McAfee should have prepared better for Microsoft Vista
IT security firm Sophos is recommending that system administrators ask their security vendors if they are capable of properly protecting them on the forthcoming 64-bit version of Vista, as arguments continue regarding access to Microsoft’s operating system code (kernel). Sophos has reassured its customers that Sophos Anti-Virus will offer full protection against malware threats on Vista, and suggests that some security vendors may not have given sufficient thought to the new operating system when developing their products.
Anti-virus firms Symantec and McAfee have recently made high-profile complaints that they are being “locked out” of the Vista operating system kernel by Microsoft’s PatchGuard prevention system. They argue that this is preventing them from continuing to develop pro-active protection against new malware, sometimes referred to as ‘host intrusion prevention’ or ‘HIPS’. They claim this action is anti-competitive.
However, Sophos argues that its approach to HIPS technology has met with no problems on both the low-spec and high-spec versions of Windows Vista. In addition, Sophos claims that Microsoft has so far provided all the interfaces that Sophos needs for providing this form of protection.
“Symantec and McAfee may be struggling with HIPS because they haven’t coded their solutions with high-spec Vista in mind,” said Richard Jacobs, CTO of Sophos. “We’ve taken a different approach, by focusing on catching bad behaviour before it has a chance to occur. Additionally, we are building our technology by making use of supported Microsoft interfaces rather than by trying to subvert them. That’s why we’re ready for 64-bit Vista, and others aren’t.”
Sophos believes that PatchGuard is a positive step by Microsoft to improve security in Windows Vista, and is not in itself anti-competitive, provided that Microsoft delivers on its commitment to provide the same level of kernel support and integration to third party security vendors as it does to its own security product team.
