Security Terms and Definitions
Term Definition
Clearing As defined in Section 8-301a of DoD 5220.22-M, clearing is 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 accept-
able level of protection.
Instrument Declassification A term that refers to procedure that must be undertaken before an instrument can be removed from a
secure environment, such as when the instrument is returned for calibration. Declassification procedures
include memory sanitization or memory removal, or both. Keysight Technologies's declassification pro-
cedures are designed to meet the requirements specified in DoD 5220.22-M, Chapter 8.
Sanitization As defined in Section 8-301b of DoD 5220.22-M, sanitization is 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 instrument is moved from a secure to a non-secure environment, such as when
it is returned to the factory for calibration.
Keysight Technologies's memory sanitization procedures are designed for customers who need to meet
the requirements specified by the US Defense Security Service (DSS). These requirements are specified
in the “Clearing and Sanitization Matrix” in Section 5.2.5.5.5 of the ISFO Process Manual.
Secure Erase Secure Erase is a term that is used to refer to either the clearing or sanitization features of Keysight Tech-
nologies's instruments.
