Over an 18-month period, what is the minimum number of EKMS spot checks required?

• A. 12
• B. 15
• C. 18
• D. 21

Answer: (C)

Spot checks verify custody and accountability of COMSEC material and are required to be performed monthly. This regular checking helps catch any discrepancies, losses, or mislabeling early, keeping EKMS records accurate. The checks are carried out by the designated COMSEC Responsible Officer or their assistant, who compare on-hand inventory to the accountability records, verify serial numbers, and inspect storage conditions.

Over an 18-month period, performing one spot check each month means you conduct 18 checks. That is the minimum because the standard calls for at least a monthly frequency, not less. The other numbers would imply doing fewer than monthly checks or more than the minimum, so they don’t represent the required minimum.
