A generic anti-spyware solution by access control list at kernel level

Our class has a project about monitoring the access patterns of processes to flag potential abnormalities. The idea is good and I think the combination of this project and the following work will be useful.

Title: A generic anti-spyware solution by access control list at kernel level

URL: http://portal.acm.org/citation.cfm?id=1063041

Abstract:

Spyware refers to programs that steal the user information stored in the user's computer and transmit this information via the internet to a designated home server without the user being aware of this transmission. Existing anti-spyware solutions are not generic and flexible. These solutions either check for the existence of known spyware or try to block the transmission of the private information at the packet level. In this paper, we propose a more generic and flexible anti-spyware solution by utilizing an access control ist in kernel mode of the operating system. The major difference between our approach and the existing approaches is that instead of asking a guard to look for the theft (spyware) or control the exit of the computer (and hence giving the spyware enough time to hide the information to be transmitted). we put a guard besides the treasure (the private information) and carefully control the access to it in the kernel mode. We also show the details of an implementation that realizes our proposed solution.
