A security policy states that patient billing records must remain unaltered during transmission between a clinic's EHR system and its billing vendor. Which tenet of the CIA triad does this requirement primarily address?
- ANon-repudiation
- BIntegrity
- CAvailability
- DConfidentiality
Show answer & explanationAnswer & explanation
Correct answer: B. Integrity
Ensuring data is 'unaltered' during transmission is the definition of integrity, which guarantees data has not been modified in transit or at rest.
Why the other options are wrong
- A. Non-repudiation is not one of the three CIA tenets.
- C. Availability ensures systems/data are accessible when needed, not about alteration.
- D. Confidentiality is about preventing unauthorized disclosure, not alteration.
CIA Triad
A security model consisting of Confidentiality, Integrity, and Availability used to guide security policy and controls.
- Confidentiality = preventing unauthorized access/disclosure
- Integrity = data accuracy and no unauthorized modification
- Availability = ensuring systems/data are accessible when needed
Memory trick: Can I Access? — Confidentiality, Integrity, Availability.
