Category Description
Decommissioning or Zeroisation In most applications EFX48 will not contain data that is
categorized as secure. However if it is considered the stored
data is commercially sensitive or has a security risk
associated with it then the following process should be
followed. It is a best practice to purge any secure data before
disposing of any device containing such data. Proper
decommissioning is described in NIST SP800-88. Eaton
recommends that products containing embedded flash
memory be destroyed to ensure any secure data is
unrecoverable.
* Figure and data from NIST SP800-88
- Embedded Memory on Boards and Devices
This includes motherboards and peripheral cards
such as network adapters or any other adapter
containing non-volatile flash memory.
Clear :
If supported by the device, reset the state to
original factory settings.
Purge
: If the flash memory can be easily identified
and removed from the board, the flash memory may
be destroyed independently from the disposal of the
board that contained the flash memory. Otherwise,
the whole board should be Destroyed. The only
possible place for secure data to be stored in EFX48
is IC2 on pcb 11786500. This is the only device that
needs to be considered.
Destroy :
Shred, Disintegrate, Pulverize, or
Incinerate by burning the device in a licensed
incinerator.
