Preface
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
fi
cation. A term that refers to procedures that must be undertaken before an instrument can be
removed from a secure environment. Declassi
fi
cation procedures include memory sanitization and memory removal,
and sometimes both.
Media storage/data export.
Any of several devices that are 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 push 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 nonsecured area.
Scrub.
The user is able to directly retrieve the memory device contents.
User-modi
fi
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.
