Periods Processing

Intervals of time when security environments are temporarily established for processing information. For example, an automated system could process Top Secret in the dedicated security mode during one period, both Confidential and Secret in the controlled security mode in a second period, and only unclassified material in a third period. The system is purged of all information and brought to a secure state when transitioning from one period to the next. There will be users during the new period who do not have clearance and need-to-know for information processed during the previous period. (AFR 205-16;)
The processing of various levels of classified information at distinctly different times with the system being properly cleared or declassified between periods of processing. (AR 380-380;)
The processing of various levels of sensitive information at distinctly different times. The Automated Information System must be purged of all information before transitioning from one period to the next whenever there will be new users who do not have clearances and the need-to-know for data processed during the previous period. (NCSC-WA-001-85;)
Processing data of a given classification level during a period of time and data of a different classification during a different period of time. Also applies to changing security mode of operation. (OPNAVINST 5239. 1A;)
