The actions taken
to render data written on media unrecoverable by both ordinary and
extraordinary means. [CNSSI_4009:2010]
A general term
referring to the actions taken to render data written on media unrecoverable by
both ordinary and, for some forms of sanitization, extraordinary means. [CNSSI_4009:2010]
1. (I) Delete
sensitive data from a file, device, or system. (See: erase, zeroize.) 2. (I)
Modify data so as to be able either (a) to completely declassify it or (b) to
downgrade it to a lower security level. [RFC4949:2007]
A general term
referring to the actions taken to render data written on media unrecoverable by
both ordinary and extraordinary means. [NIST-SP800-53:2013] [NIST-SP800-88:2006]
Process to remove
information from media such that data recovery is not possible. It includes
removing all classified labels, markings, and activity logs. [FIPS-200:2006] [NIST-SP800-88:2006]
A physically
destructive method of sanitizing media; the act of separating into component
parts. [NIST-SP800-88:2006]
A physically
destructive method of sanitizing media; the act of burning completely to ashes.
[NIST-SP800-88:2006]
A physically
destructive method of sanitizing media; to be changed from a solid to a liquid
state generally by the application of heat. [NIST-SP800-88:2006]
Writing patterns
of data on top of the data stored on a magnetic medium. NSA has researched that
one overwrite is good enough to sanitize most drives. See comments on
clear/purge convergence. [NIST-SP800-88:2006]
A sanitization
method for optical media, such as CDs. [NIST-SP800-88:2006]
A physically
destructive method of sanitizing media; the act of grinding to a powder or
dust. [NIST-SP800-88:2006]
An overwrite
technology using firmware based process to overwrite a hard drive. Is a drive
command defined in the ANSI ATA and SCSI disk drive interface specifications,
which runs inside drive hardware. It completes in about 1/8 the time of 5220
block erasure. It was added to the ATA specification in part at CMRR request.
For ATA drives manufactured after 2001 (Over 15 GB) have the Secure Erase
command and successfully pass secure erase validation testing at CMRR. A
standardized internal secure erase command also exists for SCSI drives, but it
is optional and not currently implemented in SCSI drives tested by CMRR. SCSI
drives are a small percentage of the worlds hard disk drives, and the command
will be implemented when users demand it. [NIST-SP800-88:2006]
A method of
sanitizing media; the act of cutting or tearing into small particles. [NIST-SP800-88:2006]
