Terms and definitions
Clearing
The process of eradicating the data on media before reusing the media so that the data
can no longer be retrieved using the standard interfaces on the instrument. Clearing is
typically used when the instrument is to remain in an environment with an acceptable
level of protection.
Sanitization
The process of removing or eradicating stored data so that the data cannot be recovered
using any known technology. Instrument sanitization is typically required when an instru-
ment is moved from a secure to a non-secure environment such as when it is returned to
the factory for calibration. (The instrument is declassified.) Keysight memory sanitization
procedures are designed for customers who need to meet the requirements specified by
the US Defense Security Service (DSS). These requirements are outlined in the “Clearing
and Sanitization Matrix” issued by the Cognizant Security Agency (CSA) and referenced
in National Industrial Security Program Operating Manual (NISPOM) DoD 5220.22M ISL
01L-1 section 8-301.
Security erase
Refers to either the clearing or sanitization features of Keysight instruments.
Instrument declassification
Procedures that must be undertaken before an instrument can be removed from a secure
environment such as is the case when the instrument is returned for calibration. Declas-
sification procedures will include memory sanitization and or memory removal. Keysight
declassification procedures are designed to meet the requirements specified by the DSS
NISPOM security document (DoD 5220.22M chapter 8).
