Common Security Framework (CSF)

Also known as: CSF, HITRUST CSF, HITRUST Common Security Framework
Simply put

The Common Security Framework (CSF) is a certifiable security control framework developed and maintained by HITRUST, a private organization, to help healthcare organizations and their vendors demonstrate their security and compliance efforts. Rather than creating requirements from scratch, it draws together and harmonizes many existing standards and frameworks into a single control library that organizations can be assessed against. Achieving HITRUST CSF certification is not a legal requirement and does not by itself establish HIPAA compliance.

Formal definition

The HITRUST CSF is a comprehensive, certifiable, risk-based control framework maintained by the HITRUST organization that harmonizes numerous (reportedly 60+) authoritative frameworks, standards, and regulatory sources into a single control library, enabling tailored, threat-adaptive assessments. In healthcare compliance contexts, covered entities and business associates commonly use it to structure and demonstrate their security posture, and its controls can be mapped to HIPAA Security Rule safeguards. However, the CSF is a private-sector framework distinct from the HIPAA statute and regulations enforced by HHS OCR; certification against the CSF may support but does not legally guarantee HIPAA compliance, and organizations remain independently responsible for meeting applicable HIPAA, HITECH, and state-law obligations. Note that 'CSF' also refers to the NIST Cybersecurity Framework, a separate voluntary framework from NIST; practitioners should confirm which framework is meant and verify control mappings against the current HITRUST CSF version.

Why it matters

For healthcare organizations navigating a fragmented regulatory landscape, the HITRUST CSF matters because it consolidates many separate standards and frameworks into a single, harmonized control library. Rather than tracking and reconciling requirements across dozens of authoritative sources independently, an organization can work from one structured set of controls that can be mapped to obligations such as HIPAA Security Rule safeguards. This harmonization is the framework's central value proposition and a key reason it is widely used by covered entities and business associates alike.

It is critical to understand what CSF certification does and does not accomplish. HITRUST is a private organization, and the CSF is a private-sector framework distinct from the HIPAA statute and regulations enforced by HHS OCR. Achieving HITRUST CSF certification is not a legal requirement, and it does not by itself establish HIPAA compliance. Organizations that treat a certificate as legal proof of compliance may misunderstand their exposure: they remain independently responsible for meeting applicable HIPAA, HITECH, and state-law obligations. Certification may support and help structure a compliance effort, but it does not legally guarantee it.

A further point of practical confusion is the acronym itself. 'CSF' also refers to the NIST Cybersecurity Framework, a separate, voluntary framework maintained by NIST. Because both frameworks are commonly abbreviated 'CSF,' practitioners should always confirm which framework is meant in a given context and verify any control mappings against the current HITRUST CSF version, as framework content is updated over time.

Who it's relevant to

Covered Entities
Healthcare providers, health plans, and healthcare clearinghouses may use the HITRUST CSF to structure and demonstrate their security posture and to map controls to HIPAA Security Rule safeguards. They should understand that certification does not by itself establish HIPAA compliance and that they remain independently responsible for meeting applicable HIPAA, HITECH, and state-law obligations.
Business Associates and Vendors
Business associates and their subcontractors frequently pursue HITRUST CSF certification to demonstrate security and compliance efforts to the covered entities and partners they serve. Certification can support due diligence and vendor assurance, but obligations to protect PHI attach through defined relationships and agreements rather than through certification alone.
Security and Compliance Officers
Security officers, privacy officers, and compliance leaders use the CSF as a harmonized control library to consolidate requirements drawn from many frameworks into one structured set. They should verify control mappings against the current HITRUST CSF version and distinguish the HITRUST CSF from the separately named NIST Cybersecurity Framework.
Auditors and Assessors
Professionals conducting or reviewing assessments rely on the CSF's tailored, risk-based methodology to evaluate an organization's controls. They should be precise that a HITRUST CSF assessment is a private-framework evaluation distinct from HHS OCR enforcement of HIPAA and should confirm scope and version details before drawing conclusions.

Inside CSF

Certifiable Control Framework
The HITRUST CSF is a comprehensive, certifiable framework of security and privacy controls developed and maintained by HITRUST, a private organization. It is not a law or regulation and is distinct from HIPAA, which is a US federal framework enforced by HHS OCR.
Harmonized Control Set
The CSF is designed to consolidate and map requirements from multiple authoritative sources, including HIPAA, into a single set of controls. This mapping is intended to help organizations address overlapping obligations, though it does not replace the underlying regulatory requirements.
Scalable and Risk-Based Structure
The CSF generally organizes controls so they can be tailored to an organization's size, complexity, and risk profile. Control applicability typically varies based on organizational and regulatory factors relevant to the entity.
Assessment and Certification Model
The CSF supports a formal assessment process that can lead to HITRUST certification. Certification is a private-sector attestation and is not a legal requirement under HIPAA.
Versioned Framework Content
The CSF is updated over time across successive versions as source requirements and threats evolve. Practitioners should confirm control specifics against the current HITRUST CSF version rather than relying on any single edition.

Common questions

Answers to the questions practitioners most commonly ask about CSF.

Does achieving HITRUST CSF certification mean my organization is HIPAA compliant?
No. HITRUST is a private organization and the HITRUST CSF is a certifiable control framework, not a law. HIPAA compliance is a legal obligation enforced by HHS OCR, and certification against the CSF does not by itself establish HIPAA compliance. While the CSF is designed to incorporate and map to HIPAA requirements among other authoritative sources, certification demonstrates conformance to the framework's controls rather than a regulatory determination of compliance. Organizations should treat CSF certification as one supporting element of a broader compliance program and continue to assess their obligations directly against the current HIPAA regulatory text, as well as any applicable state law and HITECH Act requirements.
Is the CSF a government-mandated or legally required framework?
No. The CSF is developed and maintained by HITRUST, a private organization, and adopting or certifying against it is not a legal requirement under HIPAA. HIPAA does not mandate any specific certification or named framework. Some healthcare organizations and their business partners choose to use the CSF voluntarily, and certain partners may require it contractually, but that is a business or contractual decision rather than a regulatory obligation. Readers should not assume that failing to adopt the CSF constitutes a HIPAA violation, nor that adopting it satisfies regulatory duties on its own.
How does the CSF relate to the HIPAA Security Rule's administrative, physical, and technical safeguards?
The CSF is generally designed to map its controls to authoritative sources, including HIPAA Security Rule requirements that span administrative, physical, and technical safeguards. Organizations often use these mappings to help organize and evidence their safeguard implementation. However, the framework's control structure is its own and does not replace the regulatory text. When using the CSF to support Security Rule work, verify the mappings against the current CSF version and confirm that your implementation addresses both required and addressable implementation specifications, keeping in mind that addressable does not mean optional.
Which types of data and information does a CSF-based program typically address?
A CSF-based program is commonly used to address the protection of sensitive information, including electronic protected health information (ePHI). Note that the HIPAA Security Rule itself governs only ePHI, whereas the HIPAA Privacy Rule covers PHI in all forms, including oral and paper. If you rely on the CSF primarily to support Security Rule obligations, confirm that your program separately accounts for Privacy Rule requirements covering non-electronic PHI, since a framework focused on information security controls may not fully address all privacy obligations.
How does using the CSF affect obligations across covered entities, business associates, and subcontractors?
The CSF may be adopted by covered entities, business associates, and their subcontractors, and some organizations use CSF certification as a way to gain assurance about partners in their supply chain. However, HIPAA obligations attach through defined relationships and flow to business associates and subcontractors through business associate agreements, not through use of the framework itself. A partner's CSF status may inform your risk assessment, but it does not substitute for the required contractual arrangements or for verifying that each party meets its own applicable obligations.
How should an organization keep its CSF work current over time?
The CSF is periodically updated by HITRUST, and its structure and control set can change across versions. Organizations should confirm which version they are working against and review updates when planning assessments or certification, since mappings to HIPAA and other sources may change. Because HIPAA regulatory text, enforcement guidance, and penalty structures are also adjusted over time, and because state law and the HITECH Act may impose additional requirements, treat CSF work as part of an ongoing program rather than a one-time effort, and periodically re-verify against current guidance.

Common misconceptions

HITRUST CSF certification proves an organization is HIPAA compliant.
HITRUST certification is a private attestation against the CSF and does not by itself establish HIPAA compliance. HIPAA compliance is determined under federal regulation enforced by HHS OCR, and an organization may hold CSF certification while still having HIPAA gaps. Certification should be treated as supporting evidence, not a legal guarantee.
The CSF is a government-mandated or legally required framework.
The CSF is developed and maintained by HITRUST, a private organization, and adopting or certifying against it is generally voluntary. It is not itself a law, though organizations may adopt it to help address requirements from frameworks such as HIPAA.
Because the CSF maps to HIPAA, implementing CSF controls fully satisfies all HIPAA obligations.
Mapping helps address overlapping requirements, but the CSF does not replace the underlying regulatory text. State law, the HITECH Act, or other frameworks may impose additional requirements, and organizations remain responsible for meeting the actual HIPAA Privacy, Security, Breach Notification, and Enforcement Rule obligations that apply to them.

Best practices

Treat HITRUST CSF certification as supporting evidence of a strong control program rather than as proof of HIPAA compliance, and maintain a separate mapping to your actual HIPAA obligations.
Confirm control specifics against the current HITRUST CSF version, since the framework is updated over time and requirements can change across editions.
Scope CSF controls to your organization's size, complexity, and risk profile so that the applicable control set reflects your actual regulatory and operational factors.
Verify that CSF adoption addresses the correct HIPAA scopes, keeping the Security Rule (ePHI) distinct from the Privacy, Breach Notification, and Enforcement Rules that may not be fully covered by security-focused controls.
Assess whether state law, the HITECH Act, or other frameworks impose additional requirements beyond those mapped in the CSF, and document any gaps.
Clarify obligations across covered entities, business associates, and subcontractors, ensuring that CSF-related expectations flowing through business associate agreements are documented and verified.
