Terms used in this document
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 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 and memory
removal, and sometimes both.
■
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.
■
Nonvolatile memory.
Data is retained when the instrument is powered off.
■
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-modifiable.
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.
