In January 2026, the U.S. Department of Health and Human Services (HHS) Office for Civil Rights (OCR) released a cybersecurity newsletter focused on system hardening and protecting electronic protected health information (ePHI). While the guidance does not introduce new HIPAA requirements, it clearly reinforces how OCR expects covered entities and business associates to operationalize the HIPAA Security Rule in today's evolving threat landscape.
The message is clear: system hardening is not optional—it is a foundational component of HIPAA compliance and cybersecurity risk management.
What Is System Hardening and Why OCR Is Emphasizing It Now
System hardening refers to the process of configuring electronic information systems to reduce their attack surface. This includes:
-
Applying patches for known vulnerabilities
-
Removing or disabling unneeded software and services
-
Changing default passwords and eliminating unused accounts
-
Enabling and properly configuring security controls
For organizations that create, receive, maintain, or transmit ePHI, these actions directly support the HIPAA Security Rule's requirement to ensure the confidentiality, integrity, and availability of that data.
OCR's renewed focus reflects what regulators continue to see in investigations and enforcement actions: preventable vulnerabilities—such as unpatched systems, legacy software, default credentials, and poorly configured access controls—remain common contributors to healthcare breaches.
Key Areas OCR Expects Organizations to Address
1. Patching Known Vulnerabilities
OCR emphasizes that patching is one of the most effective ways to reduce cyber risk. Operating systems, applications, databases, firmware, and network devices must all be included in patch management processes. Importantly, patching is not a one-time activity—new vulnerabilities continue to emerge, even in previously patched systems.
OCR also reinforces the importance of maintaining a current IT asset inventory, enabling organizations to understand what systems exist, where ePHI resides, and which assets require ongoing security attention.
2. Removing or Disabling Unneeded Software and Services
Unused applications, features, and services expand the attack surface and introduce unnecessary risk. OCR highlights common examples such as:
-
Pre-installed software that is never used
-
Unsecure or unnecessary remote access services
-
Software accounts created during installation that remain after removal
Default or leftover privileged accounts have been repeatedly identified in OCR investigations. Organizations are expected to change default passwords, remove unused accounts, and ensure old service accounts do not linger unnoticed.
3. Enabling and Configuring Security Measures
System hardening also includes making sure security controls are properly implemented and configured. This may involve native operating system features or third-party solutions such as anti-malware, endpoint detection and response (EDR), or security information and event management (SIEM) tools.
OCR connects these technical controls directly to HIPAA Security Rule standards, including:
-
Access controls
-
Encryption
-
Audit controls
-
Authentication
Risk analysis and risk management decisions should guide which controls are implemented and how they are configured.
4. Establishing and Maintaining Security Baselines
OCR highlights the value of security baselines—standardized security configurations applied consistently across systems. Resources such as NIST SP 800-53, Microsoft Security Baselines, and DoD STIGs can help organizations define and implement appropriate settings.
However, OCR cautions that baselines must be understood, tailored, and documented. Applying a baseline without evaluating how it fits the organization's environment and risk profile may create gaps rather than reduce risk.
System Hardening Is an Ongoing Compliance Obligation
A key theme throughout the OCR newsletter is that system hardening is not "set it and forget it." As threats evolve and technology changes, regulated entities must continually evaluate whether safeguards remain effective.
The HIPAA Security Rule requires periodic evaluations and updates to security measures when environmental or operational changes affect ePHI. Failure to reassess and adjust can expose organizations to compliance risk—even if controls were once sufficient.
