What controls limit CO/AO system access?

Controlling access to the CO/AO system relies on strong access-control practices that tie permissions to an individual’s role and need to know. Role-based access ensures people only get the privileges required for their duties. Least privilege tightens this by granting the minimum permissions necessary, so an error or compromise cannot cascade. Strong authentication verifies identity before granting access, reducing the chance of unauthorized logins. Regular access reviews keep permissions aligned with current roles and revoke access when it’s no longer justified, catching drift over time. Together, these elements create a robust framework for limiting who can access the CO/AO system and what they can do within it. Encryption of data at rest protects information if storage is breached, but it doesn’t decide who is allowed to log in or what they can do once authenticated. Mandatory vacations help detect irregularities and enforce separation of duties, not direct access control. Physical security controls reduce the risk of tampering with hardware or facilities, but they don’t govern digital system access.
