8.1.7.
Sanitizing Based on DoD 5220.22-M
The USA DoD 5220.22-M National Industrial Security Program Operating Manual (NISPOM),
January 1995, specifies the sanitization processes for each media type (in order to be considered
declassified) in Chapter 8, Automated Information System Security. For the flash EPROM media
type, the sanitization process is as follows:
•
“Overwrite all addressable locations with a single character.”
Then
•
“Perform a full chip erase as per manufacturer’s data sheet.”
M-Systems’ enhanced Security Erase feature complies with the above requirements, as follows:
•
Activate the Fill-Format option, set to fill the media with zeros (see Sections 8.1.4 and
8.1.5).
Then
•
Perform a full Security Erase (see Section 8.1.1).
8.1.8. Sanitizing
Based on NSA Manual 130-2
The USA National Security Agency (NSA) specifies the procedure for sanitizing semiconductor
memory devices in its 130-2 Media Declassification and Destruction Manual (Paragraph 5,
Section 7). Flash components fit the Electrically Erasable Programmable Memory (EEPROM)
category, and sanitizing is performed as follows (excerpted from the 130-2 Media
Declassification and Destruction Manual):
•
“Pulse the erase control gate and verify the erasure.”
Then
•
“Overwrite all bit locations with arbitrary unclassified data.”
M-Systems’ enhanced Security Erase feature complies with the above requirements, as follows:
•
Perform a full Security Erase (see Section 8.1.1).
Then
•
Activate the Fill-Format option, set to fill the media with a random pattern (see Sections
8.1.4 and 8.1.5).
