Covert Channel Paper

I wrote a paper for my Operating Systems class this recent semester about covert channels.
Abstract
A thirty year-old problem, covert channels continue to plague the security of modern operating systems. These channels are explained and discussion of the subject is motivated. A short evolution of the problem is given as well as several classifications of covert channels. Several methods such as type enumeration, flow analysis, virtualization, and adding noise are discussed and analyzed. Finally, one system is evaluated in context of those methods and future directions into covert channel research are suggested.
