Estimados profesionales,

Remito un interesante documento borrador del NIST sobre saneamiento de medios de
almacenamiento que ofrece directivas claras sobre el tema. Espero sea de su

Resumen Ejecutivo
Information systems capture, process, and store information using a wide variety
of media. This information is located not only on the intended storage media
but also on devices used to create, process, or transmit this information. This
media may require special disposition in order to mitigate the risk of
unauthorized disclosure of information and to ensure its
confidentiality. Efficient and effective management of information created,
processed, and stored by an information technology (IT) system throughout its
life (from inception through disposal) is a primary concern of an information
system owner.

With the more prevalent use of increasingly sophisticated encryption, an
attacker wishing to gain access to an organization?s sensitive information is
forced to look outside the system itself for that information. One avenue of
attack is the recovery of supposedly deleted data from media. These residual
data may allow unauthorized individuals to reconstruct data and thereby gain
access to sensitive information. Sanitization can be used to thwart this attack
by ensuring that deleted data cannot be easily recovered.

When storage media are transferred, become obsolete, or are no longer usable or
required by an information system, it is important to ensure that residual
magnetic, optical, or electrical representation of data that has been deleted
is not easily recoverable. Sanitization refers to the general process of
removing data from storage media, such that there is reasonable assurance,
in proportion to the confidentiality of the data, that the data may not be
retrieved and reconstructed.

This guide will assist organizations and system owners in making practical
sanitization decisions based on the level of confidentiality of their
information. It does not, and cannot, specifically address all known types of
media; however, the described sanitization decision process can be applied
