CMMC to HIPAA: Mapping Security Controls
Post Summary
Healthcare organizations often juggle two critical frameworks: CMMC (focused on protecting Controlled Unclassified Information or CUI) and HIPAA (designed to safeguard electronic Protected Health Information or ePHI). While these frameworks share some overlap, they also differ in key areas. Here's what you need to know:
- CMMC prioritizes confidentiality, aligning with NIST SP 800-171, but lacks strong controls for data integrity and availability.
- HIPAA covers the full CIA triad (Confidentiality, Integrity, Availability) with 19 standards and 36 implementation specifications.
- CMMC aligns with 13 of HIPAA’s 19 standards but only 6 of its 14 required implementation specifications.
- Healthcare contractors handling both CUI and ePHI must supplement CMMC with additional controls from NIST SP 800-53 to meet HIPAA requirements.
Both frameworks are critical for compliance, but neither fully addresses the other's gaps. Combining them with tools like Censinet RiskOps™ can simplify compliance and enhance security measures. Keep reading for a deeper look into their differences, implementation requirements, and strategies for integration.
CMMC vs HIPAA Security Framework Comparison for Healthcare Organizations
1. CMMC (Cybersecurity Maturity Model Certification)
Security Control Framework
The CMMC framework takes its foundation from NIST SP 800-53, tailoring its moderate baseline to prioritize confidentiality in nonfederal systems. Its primary goal is to secure Controlled Unclassified Information (CUI) within federal agency supply chains by mandating third-party assessments, as outlined in NIST SP 800-171.
For healthcare organizations serving as federal contractors, this framework is particularly relevant. Many CUI categories, such as Health Information and Genetic Information, overlap with electronic Protected Health Information (ePHI). However, while CMMC focuses strongly on confidentiality, it doesn't fully align with HIPAA requirements, leaving critical gaps that organizations must address.
Implementation Requirements
CMMC Level 2 applies to all nonfederal system components that handle, store, or transmit CUI. This also includes components responsible for providing security for such systems. Notably, NIST SP 800-171 Revision 3 reinstated essential policy and procedure requirements (section 03.15.01) that had been omitted in Revision 2.
Despite its strengths, CMMC falls short in areas like data integrity and system availability. For example, it lacks controls for preventing unauthorized data alterations and omits comprehensive contingency planning and disaster recovery measures - key elements of HIPAA compliance. Healthcare contractors, therefore, need to bolster CMMC with additional NIST SP 800-53 controls, such as CP-9 (contingency planning) and SI-7 (software integrity), to achieve a more complete compliance framework.
Audit and Compliance Processes
CMMC requires third-party assessments, as detailed in the CMMC Level 2 Assessment Guide. This guide integrates the security requirements of NIST SP 800-171 with the assessment objectives from NIST SP 800-171A, creating a unified compliance process. Since March 2026, healthcare organizations have started using AI-driven "Assessor Agents" to streamline third-party risk management in healthcare and modernize healthcare Governance, Risk, and Compliance (GRC)[2].
To bridge the gaps between CMMC and HIPAA, healthcare entities can utilize advanced cybersecurity and risk management tools like Censinet RiskOps™. These solutions not only support compliance efforts but also prepare organizations for the broader security demands of HIPAA, which will be explored further in the next section.

2. HIPAA (Health Insurance Portability and Accountability Act) Security Rule
Security Control Framework
The HIPAA Security Rule takes a broader approach compared to CMMC by focusing on protecting the entire CIA triad - Confidentiality, Integrity, and Availability - for all electronic Protected Health Information (ePHI). While CMMC primarily emphasizes confidentiality, HIPAA promotes a more balanced, integrated system of controls. These controls are divided into three categories: Administrative, Physical, and Technical safeguards.
HIPAA provides flexibility with its 19 standards, which include 14 mandatory and 22 optional implementation specifications. Organizations are required to adopt reasonable measures to meet these standards or document alternative solutions that achieve the same goals. The rule applies to two main groups: Covered Entities (such as health plans, clearinghouses, and healthcare providers) and Business Associates (subcontractors managing ePHI). Additionally, a 2021 amendment to the HITECH Act allows the Office of Civil Rights (OCR) to consider the use of recognized security practices - like NIST CSF or HICP - when investigating violations and determining penalties [1]. This framework lays a solid foundation for implementing detailed security measures across healthcare organizations.
Implementation Requirements
HIPAA's safeguards address various aspects of ePHI protection:
- Administrative safeguards include tasks like conducting risk analyses, managing risk, appointing security officers, and creating contingency plans for emergencies.
- Physical safeguards focus on controlling facility access and ensuring the security of equipment through proper records and backup processes.
- Technical safeguards cover integrity controls (e.g., 164.312(c)) and emergency access procedures, ensuring data remains accurate and accessible. These technical measures also emphasize data availability and integrity, areas where CMMC places less emphasis [1].
Audit and Compliance Processes
HIPAA compliance has evolved significantly. What once involved manual tracking with spreadsheets has transitioned to automated, cloud-based systems integrated into modern RiskOps frameworks. These tools allow organizations to collaborate with risk networks - often involving over 50,000 vendors - to securely share data and streamline risk assessments.
Matt Christensen, Sr. Director GRC at Intermountain Health, highlights the complexity of the healthcare industry: "Healthcare is the most complex industry... You can't just take a tool and apply it to healthcare if it wasn't built specifically for healthcare" [2].
Risk Management Support
Effective risk management builds on these audit processes to turn compliance into actionable security measures. Platforms like Censinet RiskOps™ enable healthcare organizations to perform ongoing risk assessments across various areas, including vendor management, patient data, and medical records. These tools also allow organizations to benchmark their cybersecurity maturity against industry standards, helping leadership allocate resources effectively.
Brian Sterud, CIO at Faith Regional Health, underscores the importance of benchmarking: "Benchmarking against industry standards helps us advocate for the right resources and ensures we are leading where it matters" [2].
Automate Framework Mapping: NIST 800-53 to HIPAA
Advantages and Disadvantages
Both frameworks offer distinct approaches to healthcare cybersecurity, each bringing unique strengths to the table. When used together, they can address a broad range of security needs. CMMC (Cybersecurity Maturity Model Certification) shines in establishing clear requirements for data confidentiality, thanks to its 110 specific controls and mandatory third-party assessments for Level 2 compliance. This structured approach ensures adherence to technical standards for protecting Controlled Unclassified Information (CUI) within supply chains. However, its focus on confidentiality creates gaps - it only satisfies about 13 of the 19 required HIPAA standards and 6 of the 14 required HIPAA implementation specifications[1]. Additionally, CMMC does not address critical areas like contingency planning and disaster recovery, which are essential for ensuring data availability and care operations in healthcare.
On the other hand, HIPAA (Health Insurance Portability and Accountability Act) takes a broader view, requiring protection of the Confidentiality, Integrity, and Availability (CIA) of electronic Protected Health Information (ePHI). Its flexible framework includes 19 standards and 36 implementation specifications that span administrative, physical, and technical safeguards[1]. This adaptability allows organizations of varying sizes to tailor "addressable" specifications to their needs. However, this flexibility comes at a cost - HIPAA doesn’t mandate specific technical controls or require formal third-party certification, which means enforcement often occurs only after a breach.
The challenge of integration becomes evident in scenarios where healthcare contractors manage both CUI and ePHI. While CMMC covers 15 of the 22 addressable HIPAA implementation specifications, it falls short in crucial areas like integrity protections (required by HIPAA 164.312(c)) and availability safeguards essential for healthcare operations[1]. To meet HIPAA’s full requirements, organizations must incorporate additional controls, such as those outlined in NIST SP 800-53 (e.g., CP-9 for system backups and SI-7 for software integrity).
Here’s a breakdown of the advantages and disadvantages for quick comparison:
| Aspect | CMMC Strengths | CMMC Weaknesses | HIPAA Strengths | HIPAA Weaknesses |
|---|---|---|---|---|
| Assessment Rigor | Third-party certification ensures accountability | Time-consuming and costly; 73% of contractors take over a year to prepare[3] | Flexible self-assessment adapts to organization size | Reactive enforcement; action often comes post-violation |
| Data Protection Focus | Strong confidentiality controls aligned with NIST SP 800-171 | Limited integrity and availability protections | Balanced CIA approach for safeguarding ePHI | No mandated technical framework; relies on "reasonable" measures |
| Scalability | Provides a clear technical baseline | Prescriptive nature can overwhelm smaller organizations | Addressable specifications scale with organizational complexity | Lack of specificity can lead to uneven implementation |
| Integration | Covers 15 of 22 addressable HIPAA specs[1] | Covers only 6 of 14 required HIPAA implementation specs[1] | Comprehensive administrative safeguards | No formal certification to verify compliance |
These comparisons highlight the need for healthcare organizations to fill gaps by integrating additional controls. While CMMC offers technical depth, its healthcare-specific shortcomings require supplementing with NIST SP 800-53 controls to fully align with HIPAA's requirements[1].
Conclusion
Mapping CMMC to HIPAA reveals both strengths and gaps for healthcare organizations striving to protect sensitive information. While CMMC effectively addresses around 13 of the 19 HIPAA-required standards related to confidentiality, it lacks coverage in critical areas like integrity and availability - both vital for healthcare operations [1]. For contractors handling Controlled Unclassified Information (CUI) and electronic Protected Health Information (ePHI), CMMC alone isn’t enough. Supplementing it with controls from NIST SP 800-53, such as CP-9 and SI-7, is necessary to fully comply with HIPAA requirements [1].
This alignment also brings regulatory advantages. Under the HITECH Act amendments, the Office for Civil Rights (OCR) considers recognized security practices, including NIST standards, when evaluating violations [1]. This encourages healthcare contractors to adopt robust security frameworks that address both CMMC and HIPAA mandates.
Healthcare organizations need specialized tools to navigate these overlapping requirements efficiently. Censinet RiskOps™ offers a solution by connecting over 50,000 vendors and products in a collaborative risk network. It automates assessments, benchmarks performance against industry standards, and helps manage enterprise and third-party vendor risks on a single platform [2].
Real-world use cases highlight the operational benefits of integrating these frameworks. By leveraging AI-powered automation and benchmarking, organizations can shift from a reactive compliance approach to proactive risk management. This not only bridges the gaps between CMMC and HIPAA but also strengthens defenses against evolving cybersecurity threats.
FAQs
If we’re CMMC Level 2 compliant, are we HIPAA compliant?
CMMC Level 2 compliance and HIPAA compliance are not the same. While CMMC emphasizes cybersecurity measures to protect confidentiality, HIPAA goes further by also addressing the integrity and availability of electronic protected health information (ePHI). To fully meet HIPAA requirements, organizations might need to adopt extra safeguards that go beyond what CMMC Level 2 mandates.
Which HIPAA areas does CMMC miss most (integrity and availability)?
CMMC places a strong emphasis on confidentiality, which is vital for protecting sensitive information. However, it offers limited attention to integrity and availability - two aspects that are crucial under HIPAA. These elements ensure data accuracy, system reliability, and consistent uptime, all of which are essential for protecting patient information and supporting seamless healthcare operations.
What NIST SP 800-53 controls should we add to close the HIPAA gaps?
To address HIPAA gaps effectively, consider integrating relevant controls from NIST SP 800-53. Key areas to focus on include:
- Access Management: Controls AC-1 through AC-20 ensure proper handling of user access, limiting exposure to sensitive data.
- Audit and Accountability: Controls AU-1 through AU-16 help track and log activities, ensuring accountability and transparency.
- Incident Response: Controls IR-1 through IR-10 provide a framework for identifying, managing, and mitigating security incidents.
- Risk Assessment: Controls RA-1 through RA-5 guide organizations in identifying and addressing potential vulnerabilities.
Additionally, pay attention to controls for System and Communications Protection (SC-1 to SC-43), Security Assessment (CA-1 to CA-7), and Physical Security (PE-1 to PE-19). These areas enhance compliance efforts and help safeguard electronic protected health information (ePHI) from potential threats.
