The Health Insurance Portability and Accountability Act (HIPAA) sets the standard for protecting sensitive patient data. Organizations that deal with protected health information (PHI) must have physical, network, and process security measures in place and follow them to ensure HIPAA Compliance. Covered entities (which include healthcare providers, health plans, and healthcare clearinghouses) and business associates that conduct certain health care transactions electronically must comply with the HIPAA Privacy Rule, which protects the privacy of individually identifiable health information, and the HIPAA Security Rule, which sets standards for the security of electronic protected health information (e-PHI).
