Which of the following is NOT a key management procedure?

Issuing keys to all employees is not considered a key management procedure because effective key management involves restricted access and controlled distribution of keys. It is essential to ensure that only authorized personnel have access to specific areas or resources. By issuing keys indiscriminately to all employees, an organization compromises its security measures and increases the risk of unauthorized access.

In contrast, the other options directly relate to maintaining security and accountability. Storing keys in a locked cabinet ensures they are safeguarded, returning and accounting for keys helps track who has access and prevents loss, and appointing a Key Control Manager establishes a designated authority responsible for overseeing key management practices. These actions contribute to an organized and secure approach to key management in a facility.
