Under which circumstances must combinations be changed?

• A. Initial use; after termination or clearance changes; if compromised; or if left unlocked unattended
• B. Only on initial use
• C. Only if compromised
• D. Never

Answer: (A)

Changing lock combinations is required whenever circumstances affect who should have access or when security status changes. At initial use you set a new combination to establish a trusted baseline. After termination or clearance changes you must update the combination so former personnel or those with reduced access cannot enter. If the combination has been compromised, you change it to prevent unauthorized entry. If a device has been left unlocked unattended, changing the combination restores a secure state and reduces risk. These situations cover both routine setup and responses to incidents. Limiting changes to only initial use ignores later access changes; limiting to only compromised overlooks routine updates and unattended-risk scenarios; never is not acceptable because security depends on timely updates.
