U.S. Geological Survey, Geological Survey Manual, Information Systems Security and Control (500.16.1) (Oct. 1982) (not available online).
The manual requires each computer facility to have a plan to ensure automated data processing support to users during interruptions, emergencies, and disasters. This plan is expected to be reviewed annually to determine whether the practices associated with retention and storage of back-up files, programs, and documentation are current, complete, and readily usable as intended.
The manual requires that access to computer files containing sensitive information be controlled. A specific individual's right to read, copy, or modify a given file should be clearly defined by the application system owner.
