File Attributes and Their Relationship to Computer Security.
Abstract
Mathematical models, previously formulated, describe the effect of imposing the government security scheme on multiprogrammed computer environments. The initial models introduced the concept of a file system having a tree-like directory structure. Each file possessed a primitive set of descriptors or attributes. This thesis undertakes a further refinement of the file system model to include security requirements governing allowable observation and modification of these file attributes. In particular, emphasis is given to the description of types of operations on the file system that are allowed within the security requirements of the model. In addition to the controls that are required for security, user or discretionary controls are formulated in an attempt to insure user defined privacy.
