Final answer:
The SF 701 "Activity Security Checklist" is used to record security checks, while the SF 702 "Security Container Check Sheet" is used to keep track of security container openings and closures.
Step-by-step explanation:
The SF 701 "Activity Security Checklist" and SF 702 "Security Container Check Sheet" are both forms used for security purposes. The SF 701 is used to record security checks that are conducted during a day to ensure that classified information remains secure. It includes sections to document the identity of the person conducting the check, the time of the check, and any irregularities found during the check.
On the other hand, the SF 702 is used to keep track of the opening and closing of security containers. It provides a record of when containers were opened, by whom, and for what reason. This helps in maintaining a chain of custody for classified materials and ensures accountability.
