What does restricting access to privileged user IDs require?

• A. Assign all privileged user IDs full administrator rights.
• B. Require multi-factor for privileged accounts only during business hours.
• C. Keep privileged IDs in secure vault and rotate keys.
• D. Restrict access to privileged user IDs to the least privileges necessary to perform job responsibilities.

Answer: (D)

The main idea here is applying the principle of least privilege to privileged user IDs. Privileged accounts have elevated capabilities that can significantly affect systems hosting cardholder data. By ensuring these IDs are limited to only the minimum permissions needed to perform each job, you reduce the risk of accidental or intentional misuse, limit the potential damage from compromised credentials, and make it easier to audit and enforce accountability. This approach also supports proper separation of duties, a key control in secure environments. Granting full administrator rights defeats least privilege and greatly increases risk. Requiring multi-factor authentication only during business hours doesn’t address the level of access itself, which needs to be restricted at all times. Keeping privileged IDs in a secure vault and rotating keys is important for credential security, but it doesn’t specify restricting those IDs to the least privileges necessary for the job. So the best practice is to tie access to the minimum rights required for each role.
