Eliminación
deliberada, completa e irreversible de los contenidos de un sistema o un
soporte de información. Se aplica cuando el soporte contiene o ha contenido
información sensible.
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]
