Question 1
Q1A regional hospital recently upgraded its electronic health record (EHR) system. The new system requires doctors to use a smart card and a PIN to log in, and it permanently records every patient file accessed, modified, or printed, linking these actions directly to the doctor's unique ID. While Confidentiality, Integrity, and Availability are maintained, which specific security concept is primarily enforced by the permanent recording of these actions?
Show answer & explanation
Correct answer: B
Accountability extends the CIA triad by ensuring that actions within a system can be traced back to a specific user or entity. By permanently recording every action linked to a doctor's unique ID, the hospital ensures that users are held responsible for their actions.
