A method controlling access to confidential patient information _____.

• A. Passwords
• B. Usernames
• C. Encryption
• D. Firewall

Answer: (A)

Access control and authentication are being tested here: the idea is to ensure only authorized personnel can view confidential patient information. Passwords serve as the credential that proves a user’s identity before Access is granted to the system or records. They are the fundamental tool that restricts entry to protected data, especially when paired with a username. Why this is the best fit among the options: a username alone identifies who is trying to access, but it doesn’t prevent access by itself; someone could use another person’s username if credentials aren’t protected. Encryption protects the data’s contents if someone gains access, but it doesn’t prevent unauthorized access to the data at the point of login—it's about securing data in storage or transit, not controlling who can log in. A firewall controls network traffic and borders, not the internal access rights of individual users to confidential records. So, passwords are the most direct method among these options for controlling who can access confidential patient information.
