Which feature is essential for protecting patient data in an EHR system?

• A. Strong authentication
• B. Open access to all users
• C. No access controls
• D. No audit trails

Answer: (A)

Ensuring identity before accessing the system is crucial for protecting patient data. Strong authentication verifies who is logging in, often using multiple factors (like a password plus a token or biometric), so only legitimate users can reach the EHR. This reduces the risk that a stolen password leads to unauthorized access and helps ensure actions in the system can be traced to a real person. In healthcare, this is foundational because patient information is highly sensitive. When authentication is strong, it supports accurate accountability and makes it much harder for an attacker to impersonate a valid user. Without robust authentication, even strict rules about who is allowed to do what (authorization) and keeping records of access (audit trails) can be undermined, because the system cannot reliably prove the user’s identity. Open access to all users would expose PHI to everyone, defeating privacy protections. No access controls removes the safeguards that restrict who can view or modify data. No audit trails leave investigators without evidence of who accessed what and when, making breaches harder to detect or respond to.
