What Is the HIPAA Privacy Rule and Security Rule? Key Differences and Compliance Essentials

Overview of the HIPAA Privacy Rule

The HIPAA Privacy Rule sets national standards for how covered entities and business associates use and disclose Protected Health Information (PHI). PHI includes any individually identifiable health information in paper, electronic, or oral form that relates to a person’s health status, care, or payment for care.

The rule governs who may access PHI and under what circumstances, applies the minimum necessary standard, and grants individuals rights over their information. You must provide a Notice of Privacy Practices, obtain valid authorizations for most non-routine uses, and document privacy policies, procedures, and workforce training.

• Scope: PHI in any form (paper, verbal, or electronic).
• Rights: Access, amendments, restrictions, confidential communications, and accounting of disclosures.
• Controls: Minimum necessary use/disclosure, role-based access, and authorization management.
• Accountability: Designated privacy official, workforce training, and compliance documentation.

Overview of the HIPAA Security Rule

The HIPAA Security Rule focuses on safeguarding electronic Protected Health Information (ePHI). It requires you to implement administrative safeguards, physical safeguards, and technical safeguards that are reasonable and appropriate to your risks, size, complexity, and technologies.

The rule is risk-based and flexible. Some implementation specifications are “required,” while others are “addressable,” meaning you must implement them if reasonable and appropriate—or document an equivalent alternative that reduces risk to an acceptable level.

• Administrative safeguards: risk assessment, risk management, training, incident response, and vendor oversight.
• Physical safeguards: facility access, workstation security, and device/media controls.
• Technical safeguards: access controls, audit controls, integrity protections, and transmission security.

Key Differences Between Privacy and Security Rules

• Scope of information: The Privacy Rule covers PHI in any medium; the Security Rule covers ePHI only.
• Focus: Privacy addresses “who may use or disclose PHI and why”; Security addresses “how to protect ePHI.”
• Individual rights: Explicit in the Privacy Rule; the Security Rule does not create new patient rights.
• Controls: Privacy emphasizes policies, permissible uses/disclosures, and minimum necessary; Security emphasizes administrative, physical, and technical safeguards.
• Methodology: Privacy relies on policy and authorization frameworks; Security requires a formal, ongoing risk assessment and risk management program.
• Documentation: Both require compliance documentation, but Security adds system-level technical and operational evidence (e.g., audit logs and configurations).

Compliance Essentials for the Privacy Rule

• Designate a privacy official to oversee policy development, training, and complaint handling.
• Publish and distribute a clear Notice of Privacy Practices and track acknowledgments.
• Apply the minimum necessary standard to routine uses and disclosures of PHI.
• Obtain and manage valid authorizations for non-routine or marketing-related uses.
• Honor individual rights to access, amendment, restrictions, confidential communications, and accounting of disclosures.
• Execute and manage Business Associate Agreements (BAAs) with vendors that handle PHI.
• Train your workforce on privacy policies, role-based access, and incident reporting.
• Maintain a sanction policy and document investigations, mitigation steps, and outcomes.
• Address state law preemption and apply more stringent state privacy protections where applicable.
• Retain privacy policies, procedures, training records, and related compliance documentation for required periods.

Compliance Essentials for the Security Rule

• Conduct and document a comprehensive risk assessment covering systems, data flows, and threats to ePHI.
• Implement risk management plans with prioritized safeguards, owners, timelines, and success criteria.
• Administrative safeguards: security management process, workforce security, security awareness training, and security incident procedures.
• Physical safeguards: facility access controls, workstation security, device and media controls, and secure disposal.
• Technical safeguards: unique user IDs, least-privilege access, multi-factor authentication, automatic logoff, and encryption of ePHI in transit and at rest where feasible.
• Audit controls: enable logging, monitor access, and regularly review audit trails for anomalies.
• Integrity protections: hashing or other mechanisms to ensure ePHI is not altered or destroyed improperly.
• Transmission security: secure email, VPNs, and TLS for interfaces and APIs.
• Contingency planning: data backups, disaster recovery, and emergency mode operations with tested procedures.
• Vendor management: due diligence, BAAs, security requirements, and ongoing oversight.
• Periodic evaluations: reassess risks, validate controls, and update compliance documentation.

Enforcement and Regulatory Authorities

The U.S. Department of Health and Human Services Office for Civil Rights (OCR) enforces the HIPAA Privacy, Security, and Breach Notification Rules. OCR investigates complaints, conducts compliance reviews, negotiates corrective action plans, and may impose civil monetary penalties for noncompliance.

State attorneys general can bring civil actions on behalf of residents, and the Department of Justice handles criminal violations involving knowing misuse of PHI. Breach notification obligations can trigger investigations, so you should maintain incident response plans and thorough compliance documentation to demonstrate due diligence.

Implementing Safeguards for PHI and ePHI

Plan with a risk assessment

• Inventory systems, applications, data stores, and vendors that create, receive, maintain, or transmit ePHI.
• Identify threats, vulnerabilities, and likelihood/impact to prioritize controls and remediation.
• Translate findings into a risk management plan and track progress in your compliance documentation.

Administrative safeguards in practice

• Establish clear policies and procedures for access, use, disclosure, and incident handling.
• Deliver role-based training and phishing awareness, and document completion.
• Execute BAAs and define security requirements, breach reporting timelines, and audit rights.
• Adopt a sanction policy and a consistent process for investigating and mitigating violations.

Physical safeguards to anchor your program

• Control facility access with badges, visitor logs, and secured server rooms.
• Harden workstations with privacy screens, automatic lockouts, and secure locations.
• Manage device and media controls, including encryption, tracking, reuse, and destruction.

Technical safeguards for ePHI

• Implement least-privilege access, unique IDs, strong authentication, and multi-factor authentication.
• Enable encryption for data in transit and at rest where reasonable and appropriate.
• Activate audit logging, monitor for anomalous behavior, and review alerts promptly.
• Use endpoint protection, patch management, secure configurations, and network segmentation.

Ongoing monitoring and improvement

• Test backups and disaster recovery procedures; refine based on results.
• Conduct periodic evaluations, tabletop exercises, and vendor reassessments.
• Update policies, risk registers, and compliance documentation as systems and threats evolve.

Conclusion

The Privacy Rule governs who may use and share PHI and the rights individuals have over it, while the Security Rule requires safeguards to protect ePHI. A risk-based program, strong administrative, physical, and technical safeguards, and meticulous compliance documentation align daily operations with HIPAA’s requirements.

FAQs

What types of information does the HIPAA Privacy Rule protect?

The Privacy Rule protects Protected Health Information (PHI), which is individually identifiable health information in any form—paper, electronic, or oral—related to health status, care provided, or payment. Names, contact details, medical record numbers, and full-face photos tied to health data are examples of PHI.

How does the Security Rule differ in scope from the Privacy Rule?

The Security Rule applies only to electronic Protected Health Information (ePHI) and requires administrative safeguards, physical safeguards, and technical safeguards to protect it. The Privacy Rule applies to PHI in any form and governs permissible uses and disclosures and individual rights.

What are common administrative safeguards required by HIPAA?

Common administrative safeguards include a documented risk assessment and risk management plan, workforce security and training, security incident procedures, contingency planning, vendor due diligence with BAAs, and ongoing evaluations. These activities must be reflected in your compliance documentation.

How are HIPAA Privacy and Security Rules enforced?

HIPAA is enforced primarily by HHS’s Office for Civil Rights through investigations, compliance reviews, corrective action plans, and civil penalties. State attorneys general may bring civil actions, and the Department of Justice can pursue criminal cases for intentional misuse of PHI.
