The HIPAA Security Rule sets standards for protecting electronic PHI (ePHI). This includes implementing administrative, physical, and technical safeguards. Administrative safeguards involve policies and procedures to manage the selection, development, and enforcement of security measures. Physical safeguards pertain to the protection of electronic systems and related buildings and equipment from environmental hazards and unauthorized intrusion. Technical safeguards involve the technology and policies that protect ePHI and control access to it.
