Final answer:
User permission reviews and separation of duties are effective procedures to mitigate privilege creep among long-term users.
Step-by-step explanation:
The procedure that should be employed to mitigate the possibility of privilege creep among long-term users is user permission reviews. Privilege creep refers to the gradual accumulation of excessive user permissions over time, allowing users more access than they need.
Conducting regular reviews of user permissions ensures that each user has only the necessary permissions required to perform their job tasks, reducing the risk of privilege creep.
For example, in a software development company, a developer who has been with the company for a long time may have accumulated unnecessary administrative privileges in addition to their development-related permissions.
By conducting user permission reviews, the company can identify and revoke any excessive privileges, thereby mitigating the possibility of privilege creep.
Separation of duties is another important practice that can help prevent privilege creep. It involves dividing crucial tasks among multiple individuals to create a system of checks and balances, reducing the risk of any single user gaining excessive privileges.
