When information, once classified highly sensitive, is no longer critical or highly valued, that information must be
A.
Destroyed
B.
Declassified
C.
Degaussed
D.
Deleted
Explanation:
B: Information classification also includes the processes and procedures to declassify information. For example, declassification may be used to downgrade the sensitivity of information. Over the course of time, information once considered sensitive may decline in value or criticality. In these instances, declassification efforts should be implemented to ensure that excessive protection controls are not used for nonsensitive information. When declassifying information,marking, handling, and storage requirements will likely be reduced.Organizations should have declassification practices well documented for use by
individuals assigned with the task. Information may still be needed and so it cannot be destroyed, degaussed, or deleted. Page 555.
