What is the purpose of access control in healthcare IT systems, and what are common mechanisms?

Access control is about preventing unauthorized data access and ensuring people can only access information appropriate to their role. In healthcare IT, protecting patient privacy and meeting regulatory requirements makes this essential. Common mechanisms include user authentication, which verifies who the user is (through passwords, tokens, or biometrics); role-based access control, which assigns permissions based on the user’s job role so each person can do only what their role requires; and audit trails, which log who accessed what data and when to provide accountability and help detect misuse. Other supportive practices include using strong authentication, applying least-privilege principles, and maintaining access control lists to specify exact permissions. The other options would either expose more data than allowed, rely on weak or uniform passwords, or remove protections altogether, all of which contradict the goal of secure, compliant access to patient information.
