Security Terms and Definitions
Term Definition
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

Sanitization
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.
A term that refers to procedures that must be undertaken before an
instrument can be removed from a secure environment, such as in 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.
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.

Summary of Memory Declassification Procedures
This section explains how to clear, sanitize, and remove memory from your
instrument, for all classes of memory that are writable during normal
operation.
NOTE
– Before you begin any memory clearing or sanitization procedures, be sure to
record all the critical information (store and recall the instrument setting and
record the IP address of the instrument). This information is essential for
successful restoration of the instrument’s operating system.
– Read this entire document before using any sanitization procedure. Failure to
do so may necessitate returning the instrument to an Authorized Keysight
Service Center for firmware downloads and recalibration.

Performing an instrument sanitization requires the instrument security option
(SEC) to be purchased.
On the front panel press:
Utilities > Test/Setup > Calibration > Reset to Factory > Yes
From the remote interface, send:
SYSTem:SECurity:IMMediate
Note: The instrument’s security setting must be unlocked to perform these
actions.
This sanitizes all user-accessible instrument memory and restarts the
instrument. This includes deleting and sanitizing all user-defined state or
preference information, user-defined I/O settings, and data logging. The
instrument’s firmware, serial/model number, MAC address, last power on
state, and calibration data are preserved.
This command complies with requirements in chapter 8 of the National
Instrument Security Program Operating Manual (NISPOM). This command is
for users, such as military contractors, who must comply with NISPOM.
Specifically, the action will fully declassify all non-volatile memory using the
methods specified in the June 28, 2007 DSS Memory Clearing and
Sanitization Matrix.
may remove the front panel assembly on which the memory chip resides.

Procedure for Declassifying a Faulty Instrument
If the instrument is not able to power on, the user information cannot be cleared
using the front panel or the remote interface. The only choice in this situation is to
take manual steps to remove any user information that may be present.
