Media Storage Requirements
Data that is no longer needed or used must be destroyed.
Object reuse - The concept of reusing data storage media after its initial use
Data remanence - Is the problem of residual information remaining on the media after erasure.
Stages of data erasure -
- Clearing: Overwriting of datamedia intended to be reused in the same organization or monitored environment.
- Purging: Degaussing or overwriting media intended to be removed from a monitored environment.
- Destruction: Completely destroying the media and therefore residual data.
