RSA5100B Series Declassi

cation and Security Instructions

Preface

This document helps customers with data security concerns to sanitize or remove memory devices from the RSA5100B
Series Real-Time Signal Analyzers.

These products have data storage (memory) devices and data output devices (USB ports). These instructions tell how to
clear or sanitize the memory devices and disable the data output devices. The instructions also tell how to declassify an
instrument that is not functioning.

Reference

The procedures in this document are written to meet the requirements speci

ed in:

NISPOM, DoD 5220.22–M, Chapter 8

ISFO Process Manual for Certi

cation & Accreditation of Classi

ed Systems under NISPOM

Products

The following Tektronix products are covered by this document:

RSA5103B

RSA5106B

RSA5115B

RSA5126B

Terms

The following terms may be used in this document:

Clear.

This removes data on media/memory before reusing it in a secured area. All reusable memory is cleared to

deny access to previously stored information by standard means of access.

Erase.

This is equivalent to clear.

Instrument Declassi

cation.

A term that refers to procedures that must be undertaken before an instrument is

removed from a secure environment. Declassi

cation procedures include memory sanitization and memory removal,

and sometimes both.

RSA5100B Series Declassi

Preface

Media storage/data export device.

Any of several devices that can be used to store or export data from the

instrument, such as a USB port.

Power off.

Some instruments have a “Standby” mode, in which power is still supplied to the instrument. For the

purpose of clearing data, putting the instrument in Standby mode does not qualify as powering off. For these products,
you will need to either press a rear-panel OFF switch or remove the power source from the instrument.

Remove.

This is a physical means to clear the data by removing the memory device from the instrument. Instructions

are available in the product Service Manual.

Sanitize.

This eradicates the data from media/memory so that the data cannot be recovered by other means or

technology. This is typically used when the device will be moved (temporarily or permanently) from a secured
area to a non-secured area.

Scrub.

This is equivalent to sanitize.

User Accessible.

User is able to directly retrieve the memory device contents.

User-modi

able.

The user can write to the memory device during normal instrument operation, using the instrument

interface or remote control.

Volatile memory.

Data is lost when the instrument is powered off.

Nonvolatile memory.

Data is retained when the instrument is powered off.

RSA5100B Series Declassi

cation and Security Instructions

Clear and Sanitize Procedures

Memory Devices

The following tables list the volatile and nonvolatile memory devices in the standard instrument and listed options.
Detailed procedures to clear or sanitize these devices, if any, are shown following each table.

Terminology

The following terms are used in the tables in this section:

User data – Describes the type of information stored in the device. Refers to waveforms or other measurement data
representing signals connected to the instrument by users.

User settings – Describes the type of information stored in the device. Refers to instrument settings that can be
changed by the user.

Both – Describes the type of information stored in the device. It means that both user data and user settings are
stored in the device.

None – Describes the type of information stored in the device. It means that neither user data nor user settings
are stored in the device.

Directly – Describes how data is modi

ed. It means that the user can modify the data.

Indirectly – Describes how data is modi

ed. It means that the instrument system resources modify the data and that

the user cannot modify the data.

Clear and Sanitize Procedures

Clearing Hard Disk Drives

If your organization's security protocols allow the use of software to purge or sanitize hard drives, you can use commercial
software to erase free space on the hard drive before sending the instrument out for upgrades or repair. Follow the
instructions that come with the software to ensure that the erasure of sensitive data from the hard drive complies with your
organization's security protocols.

Sequence for clearing secure data from a hard drive:

Delete all stored signals and instrument settings

les (all

les stored with a

tiq

csv

, or

Setup

extension).

Acquire several full memory-length acquisitions of noise (no signal attached to the input).

Without Option 53, acquire a full-length acquisition 4 times.

With Option 53, acquire a full-length acquisition 16 times.

Close the RSA5100B application and erase the free space on the hard disk using commercial software.

Fixed Hard Drive Removal

Procedure

The following procedure applies to instruments with Option 59 (Fixed Hard Disk Drive) installed. This procedure is an
overview of the removal process. For detailed removal and replacement procedures, see the

RSA5100B Series Real-Time
