The duplicate keys are exchanged with in-use keys every ?

• A. Six months
• B. Three months
• C. One year
• D. Monthly

Answer: (A)

Regular rotation of keys is a security control for protecting access to storerooms and controlled areas. Exchanging duplicate keys with the keys currently in use every six months limits the window of opportunity if a key is lost, duplicated, or if a staff member who had access leaves the organization. It helps maintain accountability and makes it easier to detect and address any compromise during audits and routine checks. Choosing a six-month interval balances security with practicality. A monthly swap would be unnecessarily burdensome, while a shorter interval than six months increases administrative workload without substantially increasing security. A full year leaves too long a period in which a compromised key could be used without detection. Thus, six months is the reasonable, commonly adopted interval.
