Data Sanitization Guidelines

NIST.SP.800-88 |
NIST 800-88, developed in 2006, revised in 2014, has now become a widely used data sanitization standard by US governments as well as private businesses and organizations. It applies to a full range of storage media types from magnetic to flash-based, from mobile devices to servers.
NIST 800-88 considers these factors to determine the sanitization method:
NIST 800-88 lists three data sanitization methods: Clear, Purge and Destroy. The guideline goes into details for each method for all possible media setup and scenarios. Verification is required at the end to ensure a successful data sanitization and information protection.
NIST 800-88 considers these factors to determine the sanitization method:
- The confidentiality levels of information
- The type of storage media
- The risk to confidentiality
- The destination of your media

DoD 5220.22-M |
The “DoD standard,” whose last major update was in 2006, is the most common data wiping method for magnetic hard drives. It specifies a process of overwriting hard disk drives (HDDs) with patterns of ones and zeros. The process requires three secure overwriting passes and verification at the end of the final pass. Erasing a magnetic hard drive using the DoD 5220.22-M data sanitization method will prevent any file recovery from the drive.
