Everyone - Symantec has just released an in depth report on the security of the Windows Vista kernel. This is a detailed technical report that discusses how Vista boots, how PatchGuard and Code Integrity work, as well as a technique on how to bypass them. You can find the paper here: http://www.symantec.com/avcenter/reference/Windows_Vista_Kernel_Mode_Sec urity.pdf These technologies introduce a number of concerns for the software industry. Some of them are discussed here: http://www.symantec.com/enterprise/security_response/weblog/2006/08/asse ssment_of_vista_kernel_mod.html If anyone thinks this is self-serving, it really isn't. These technologies have real implications on the future of software development.
