Silicon Graphics IRIX Sanitization Overwrite ProceduresAdded by Papergrl
Description:
Maintaining the confidentiality of sensitive information is a fundamental mission of a computer security program. Ensuring that sensitive information is securely removed from computer media prior to release is a critical layer of security. This document references a United States Department of Defense three-pass overwrite standard and then describes procedures that are used to overwrite media according to that standard using the Silicon Graphics Incorporated IRIX operating system "FX" utility. The basic operation of this low level disk exerciser utility is discussed, including alternatives and other ancillary risk management considerations. Then specific direction and visual aides are provided to instruct the reader how to set the correct pattern for each overwrite pass, how to write that pattern over all addressable locations, and how to verify that the overwrite performed correctly.
