If you work in IT, cybersecurity, or digital compliance for a healthcare organization, you’ve likely heard “HIPAA compliance” more times than you can count. But beyond the policies and paperwork, HIPAA (the Health Insurance Portability and Accountability Act of 1996) defines a critical framework for how protected health information (PHI) must be handled, stored, and secured in the U.S.
HIPAA as an Information Security Standard
At its core, HIPAA is an information security standard that sets expectations for confidentiality, integrity, and availability of sensitive medical data. When HIPAA was enacted, the law’s goal was to create uniform national standards for how patient information could be accessed and shared electronically.
For IT and security professionals, this meant:
- Implementing consistent data protection controls across networks, devices, and applications.
- Defining clear access management and auditability standards.
- Ensuring data interoperability without sacrificing confidentiality.
Who is responsible for what?
From a security architecture perspective, HIPAA identifies two main groups responsible for PHI:
Both must comply with HIPAA’s Privacy and Security Rules. That means IT service providers, cloud infrastructure operators, and consultants working with PHI all share legal accountability for protecting it.
A Business Associate Agreement (BAA) formalizes this, defining security responsibilities, incident response obligations, and breach notification processes.
The core rules: privacy, security, and breach notification
We can summarize HIPAA’s main rules as follows:
- The Privacy Rule sets boundaries for how PHI can be used or disclosed. While this rule primarily affects administrative and clinical processes, IT teams must ensure systems enforce minimum necessary access and maintain audit trails of all data interactions.
- The Security Rule defines the technical, physical, and administrative safeguards for electronic PHI (ePHI). This is the heart of HIPAA for security professionals and breaks down into:
- Administrative safeguards: Risk assessments, training, and incident response plans.
- Physical safeguards: Access controls for servers, workstations, and portable media.
- Technical safeguards: Encryption, authentication, and integrity controls for ePHI in storage and transit.
- The Breach Notification Rule requires timely reporting of any unauthorized access or disclosure of PHI. Affected individuals, the U.S. Department of Health and Human Services (HHS), and sometimes the media must be notified, depending on the scale of the incident.
What are PHI's?
For IT systems, that means PHI isn’t limited to medical records; it can appear in:
Security controls must therefore protect all environments where PHI could exist, including temporary storage, developer sandboxes, and SaaS platforms.
Compliance in practice
HIPAA doesn’t prescribe exact tools or technologies. Instead, it requires organizations to implement “reasonable and appropriate” safeguards based on risk assessment.
In practice, this aligns closely with modern cybersecurity frameworks such as NIST SP 800-53 and ISO/IEC 27001.
Key focus areas include:
- Access Control: Role-based access, MFA, and least privilege enforcement.
- Audit Controls: Centralized logging, monitoring, and event correlation for PHI systems.
- Integrity Controls: Hashing, checksums, and versioning to prevent unauthorized data alteration.
- Transmission Security: TLS 1.2+ encryption for data in motion; secure VPNs for remote access.
- Data at Rest Security: Full-disk encryption, key management, and secured backups.
- Incident Response: Documented playbooks, breach reporting workflows, and post-incident analysis.
Common technical missteps
Even well-intentioned teams can fall short of compliance. Common technical missteps include unencrypted data backups stored on shared cloud drives, weak access policies (e.g., shared accounts or lack of session timeouts), incomplete logging that fails to capture PHI access events, improper disposal of hardware containing ePHI, and third-party integrations without a signed BAA.
In the event of an audit or data breach, any of these can lead to serious financial and reputational damage.
Penalties and enforcement
HIPAA enforcement is handled by the Office for Civil Rights (OCR) under HHS. Fines are tiered based on the level of negligence:
- Tier 1: $100-$50,000 per violation for unintentional breaches.
- Tier 4: Up to $1.5 million per year for willful neglect without correction.
Emerging security challenges
HIPAA was written before cloud computing, mobile health apps, and IoT medical devices became standard. While it has evolved through guidance updates, many modern systems operate at the edge of HIPAA’s definitions.
Security professionals must now consider telehealth platforms and remote patient monitoring devices, AI tools processing sensitive health data, and Integration with non-HIPAA-covered systems (e.g., wearable data or wellness apps).
These require zero-trust principles, continuous monitoring, and data governance that extend beyond traditional perimeter defences.
When implemented well, HIPAA not only prevents regulatory penalties; it strengthens overall cybersecurity resilience and builds patient trust.
