Guide to Understanding Trusted Recovery in Trusted Systems

摘要

This document provides a set of good practices related to the design andimplementation of trusted recovery functions for systems employed for processing classified and other sensitive information. It provides guidance to manufacturers on what functions of trusted recovery to incorporate into their systems, and to system evaluators on how to evaluate the design and implementation of trusted recovery functions. It contains suggestions and recommendations derived from Trusted Computer System Evaluation Criteria (TCSEC) objectives but which aren't required by the TCSEC. This guideline isn't a tutorial introduction to the topic of recovery but is a summary of trusted recovery issues that should be addressed by operating systems designed to satisfy the requirements of the B3 and Al classes, Computer security: Trusted Computer System Evaluation Criteria (TCSEC); automated data processing (ADP); trusted recovery; operating systems.
