Abstract

Security can not be attained in the absolute sense. Every security system seeks to attain a probability of loss which is commensurate with the value returned by the operation being secured. For each activity which exposes private, valuable, or classified information to possible loss, it is necessary that reasonable steps be taken to reduce the probability of loss. Further, any loss which might occur must be detected. There are several minimum requirements to establish an adequate security level for the software of a large multi-programmed system with remote terminals.
