8.1.9. Sanitizing
Based
on USA Air Force AFSSI 5020
The USA Air Force System Security Instruction (AFSSI) 5020, dated 20 August, 1996, specifies
the procedure for sanitizing confidential media. Chapter 5, Semiconductor Devices, describes the
security procedure for all types of semiconductor media. In paragraph 5.3, the procedure for
sanitizing flash memory is described as follows:
•
“Pulsing the erase control gate and verifying 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).
8.1.10.
Sanitizing (Purging) Based on USA Army Regulation 380-19
The USA Army Regulation 380-19, Information Systems Security (ISS), effective 27 March,
1998, provides the security requirements for systems processing Special Access Program (SAP)
information and describes the ISS policy as it applies to security in hardware, software
procedures, telecommunication, personal use, physical environment, networks and firmware.
Section VII, Automated Information System Media, Section 2-20, describes cleaning, purging,
declassifying and destroying media. Appendix F-2 describes the following for sanitizing Flash
EPROM (FEPROM):
•
“Overwrite all locations with a random character, a specific character, then its complement.”
Then
•
“Check with the DAA (Designated Approval Authority)/SCO (Service Certifying
Organization) to see if additional procedures are required.”
M-Systems’ enhanced Security Erase feature complies with the above requirements, as follows:
•
Activate the Fill-Format option, set to fill the media with a random pattern (see Sections
8.1.4 and 8.1.5).
Then
•
Activate the Fill-Format option again, set to fill the media with zeros (see Sections 8.1.4 and
8.1.5).
Then
•
Perform a full Security Erase, which fills the media with ones (see Section 8.1.1).
