Preface
Preface
This document helps customers with data security concerns to clear or sanitize 4 Series MSO instruments without factory-installed Option
4-SEC.
This series of instruments contain a processor system with non-removable mass storage.
These products have data storage (memory) devices and data export interfaces (USB and Ethernet). These instructions describe how to
clear or sanitize the memory devices and disable the data output 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
Supported products
Tektronix 4 Series Mixed Signal Oscilloscope products are covered by this document.
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.
