Purging information is
|“||a media sanitization process that protects the confidentiality of information against a laboratory attack.||”|
|“||[t]he removal of sensitive data from an AIS at the end of a period of processing, including from AIS storage devices and other peripheral devices with storage capacity, in such a way that there is assurance, proportional to the sensitivity of the data, that the data may not be reconstructed through open-ended laboratory techniques. An AIS must be disconnected from any external network before a purge.||”|
Purging of records is
|“||[t]he removal and/or destruction of records because they are deemed to be of no further value or further access to the records would serve no legitimate government interest.||”|
There are three general methods of purging media:
- ↑ NIST Special Publication 800-88, at 8.
- ↑ A Guide to Understanding Data Remanence in Automated Information Systems.
