What does the Security Rule address?

The Security Rule specifically focuses on establishing standards for safeguarding electronic Protected Health Information (ePHI). This regulation is part of the Health Insurance Portability and Accountability Act (HIPAA) and aims to ensure the confidentiality, integrity, and availability of ePHI by implementing administrative, physical, and technical safeguards. These safeguards include measures such as access controls, encryption, and security audits, which are essential for protecting sensitive health information that is stored or transmitted electronically. This is critical in today's digital environment, where breaches of electronic medical records are a significant concern.

The other options, while relevant to the health sector, do not pertain to the specific focus of the Security Rule. Quality improvement in healthcare relates to broader healthcare practices and policies, and safeguarding paper health records is more aligned with the Privacy Rule rather than the Security Rule, which concentrates solely on electronic data. Guidelines for physical health facilities may cover aspects of compliance and safety but are not directly tied to the protection of ePHI as outlined by the Security Rule. Thus, the correct choice highlights the specific intent and directives of the Security Rule within HIPAA.
