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 acceptable level of protection.
Instrument
A term that refers to procedures that must be undertaken before an instrument can be removed
Declassification
from a secure environment, such as is the case when the instrument is returned for calibration.
Declassification procedures include memory sanitization or memory removal, or both. Keysight
declassification procedures 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 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
instruments.
