6 Series Low Profile Digitizer (LPD64) With Factory Opt. 6-SEC Enhanced Security Instrument Declassification and Security Instructions 3

Preface
This document helps customers with data security concerns to clear or sanitize a Tektronix 6 Series Low Profile Digitizer (LPD64)
instrument with factory installed option 6-SEC.
The instrument has data storage devices (memory and a removable mass storage drive) and data export interfaces (USB and Ethernet).
These instructions describe how to clear or sanitize the memory devices and disable the data export interfaces. The instructions also
describe how to sanitize an instrument that is not functioning.
Reference
The procedures in this document are written to meet the requirements specified in:
• National Industrial Security Program Operating Manual (NISPOM), DoD 5220.22–M, Chapter 8
• Defense Security Service Manual for the Certification and Accreditation of Classified Systems under the NISPOM
Terms
The following terms may be used in this document:
•Clear. This eradicates 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.
•Media. Storage/data export device. A device that stores or exports data from the instrument, such as a USB flash drive or USB port.
•Sanitize. This removes the data from media/memory so that the data cannot be recovered using any known technology. This is
typically used when the device is moved (temporarily or permanently) from a secured area to a nonsecured area.
•Scrub. This is equivalent to sanitize.
•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.
•User Accessible. The user can directly retrieve the memory device contents.
•User-Modifiable. The memory device can be written to by the user during normal instrument operation, using the instrument user
interface or remote control.
•Volatile memory. Memory that loses data when the instrument is powered off.
•Nonvolatile memory. Memory that retains data when the instrument is powered off.
•Power off. Some instruments have a “Standby” mode, in which power is still supplied to the instrument. For clearing data, putting the
instrument in Standby mode does not qualify as powering off. For these products, you must either push a rear-panel OFF switch or
remove the power source from the instrument.
•Instrument Declassification. A term that refers to procedures that must be undertaken before an instrument can be removed from a
secure environment. Declassification procedures include memory sanitization, memory removal, and sometimes both.
Supported products
This document covers the Tektronix 6 Series Low Profile Digitizer (LPD64) product with factory option 6-SEC installed.
Note: Option 6-SEC must be ordered at the same time you order an instrument.
About option 6-SEC
Note: Option 6-SEC must be ordered at the same time you order an instrument.
Option 6-SEC provides the highest level of instrument security for the LPD64. Option features include:
• Instrument hardware that is configured to easily declassify the instrument:

• The main system memory is easily removed without disassembling the instrument.
• Data can only be saved to or read from a USB port on the instrument, a mounted network drive, or through the programmatic
interface.
• Password protection to enable/disable external USB Host and Device ports.
• Password protection to enable/disable firmware upgrades or downgrades.
• Password protection to prevent BIOS modification and booting from USB flash devices.

Memory device clear and sanitize procedures
Nonvolatile, volatile memory device table terminology
The tables in this section use the following terms:
•User data. Describes the type of information stored in the device. Refers to waveforms or other measurement information 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 or user settings are stored in the device.
•Directly. Describes how data is modified. It means that the user can modify the data.
•Indirectly. Describes how data is modified. It means that the instrument system resources modifies the data and that the user cannot
modify the data.
