Abstract

Methods and apparatus are provided for information assurance in a multiple level security (MLS) combat system. A plurality of tasks are executed, where at least one of the tasks requiring a transition from a first security level to a second security level. At least one of the tasks are executed on a cloud computing system; and a kernel is employed to prevent a leakage of data between at least two of the tasks. The cloud computing system comprises a virtualization layer and provides one or more operating systems, as well as interface access control to data. The kernel provides a mechanism for the transition from the first security level to the second security level. The kernel optionally tags one or more data records with a security classification to allow one or more classification levels to be segregated for role-based data access.
