RHIA Exam - Question 126

Access control involves restricting access to resources to authorized individuals only. Techniques employed for access control typically include mechanisms such as automatic logoff, passwords, tokens, and unique user identification. Automatic logoff prevents unauthorized access when a user is not actively using a system, passwords authenticate users, tokens can act as a physical or digital key, and unique user identification ensures that each user has a distinct identifier. Therefore, all the options listed contribute to access control measures.
