Clear and sanitize procedures

This document helps customers with data security concerns to clear or sanitize 4 Series MSO instruments.
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.

Terminology

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 non secured 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.

The following terms may be used in the volatile and non-volatile memory device tables:

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.

How to sanitize a working instrument

Sanitize means that all data in non-volatile memory is changed or overwritten such that the original data is no longer in memory, and that the data cannot be recovered using any known technology. You typically do a sanitize operation when you:
- Turn the instrument over to another person or department
- Move an instrument (temporarily or permanently) from a secured area to a non secured area
- Send an instrument to Tektronix for calibration and/or repair

Sanitizing is done through commands on the instrument. To sanitize the instrument:

Remove any USB memory devices from the instrument, and store or destroy the USB memory devices in accordance with your organization’s guidelines.
Clear the Network Configuration password (if set):
Enter the instrument’s IP address into a Web browser on a PC that has network access to the instrument.
Click the Security for Network Config link on the left side of the screen.
Click Submit:
If a password was set for this function, you are requested to enter the password. If the password is accepted, the password is set to blank (the default setting of the access password fields).
If a password was not set for this function, the screen displays the message that the password was successfully changed (to a blank password).
Clear the network mDNS Hostname and description:
Enter the instrument’s IP address into a Web browser on a PC that has network access to the instrument.
Click the Network Configuration link on the left side of the screen.
Delete any existing text in both of the Host Settings fields.
Click the Host Settings Submit button. A message appears stating that the field is empty, and will be configured to the original factory default value.
