Abstract
The Minimum Security Requirements for Multi-User Operating Systems (MSR) document provides basic commercial computer system security requirements applicable to both government and commercial organizations. These requirements include technical measures that can be incorporated into multi-user, remote -access, resource-sharing, and information-sharing computer systems. The MSR document was written form the prospective of protecting the confidentiality and integrity of an organization\'s resources and promoting the continual availabiliy of these resources. The MSR presented in this document from the basis for the commercially oriented protection profiles in Volume II of the draft Federal Criteria for Information technology Security document (known as the federal Criteria). The Federal Criteia is currently a draft and supersedes this document.
The MSR document has been developed by the MSR Working Group Working Group of the Federal Criteria Project under National Institute of Standards and Technology (NIST) leadership with a high level of private sector participation. Its contents are based on the Trusted Computer System Evaluation Criteria (TCSEC) C2 critetria class, with additions from current computer industry practice and commercial security requirements specifications.
