While there has been research on protecting the host against compromise by malicious guests, research on protecting the guests against a compromised host is limited. In this paper, we present an access control solution which prevents the host from gaining access into the guest containers and their data. Using system call interception together with the built-in AppArmor mandatory access control (MAC) approach the solution protects guest containers from a malicious host attempting to compromise the integrity of data stored therein. Evaluation of results have shown that it can effectively prevent hostile access from host to guest containers while ensuring minimal performance overhead.
