What governs the HIPAA Security Rule?

The HIPAA Security Rule specifically applies to electronic protected health information (ePHI). This rule was established to set standards for the protection of ePHI to ensure its confidentiality, integrity, and availability. It outlines the administrative, physical, and technical safeguards that covered entities and business associates must implement to protect ePHI from unauthorized access and breaches.

The focus on electronic protected health information is critical in our increasingly digital healthcare landscape, where sensitive data is often transmitted and stored electronically. By concentrating on ePHI, the Security Rule addresses the unique risks associated with electronic data, contrasting with the privacy and security measures for written or oral health information.

In light of this focus, the other options aren't applicable. The written health information and all forms of protected health information fall under the HIPAA Privacy Rule, which addresses the broader scope of handling and protecting all types of health information, not just those that are electronic.
