A General Security Marking Policy for Classified Computer Input/Output Material
Abstract
A security marking policy has two objectives: (1) to fulfill the basic marking requirements of the security regulations for all types of computer I/O material on a consistent, generalized basis, and (2) to ensure that the security attributes of classified data are accurately maintained on every I/O transfer. The reasons behind the need for a general policy are considered, the guidance provided by existing regulations is reviewed, and the marking policies of three existing systems are outlined. The basic concept of multilevel I/O is defined. a set of groups of I/O techniques is established, and two distinct marking policies, one for unilevel I/O and one for multilevel, are presented. Finally, an overview of the considerations involved in the implementation of trustworthy computer labeling is provided.
