Shared Responsibility and Inheritance Program

Also known as: SRIP, HITRUST Shared Responsibility and Inheritance Program, HITRUST Shared Responsibility Program, Shared Responsibility Matrix (SRM)

Simply put

The Shared Responsibility and Inheritance Program is a HITRUST offering that helps organizations clarify which security controls are handled by a service provider (such as a cloud vendor) versus by the customer using that service. It also lets a customer reuse, or 'inherit,' controls that a qualifying service provider has already put in place, which can streamline third-party risk management and the customer's own HITRUST assessment. Because this is a HITRUST program run by a private organization, participation is not a legal requirement and does not by itself establish HIPAA compliance.

Formal definition

A HITRUST program that defines shared responsibility models and inheritance mechanisms for organizations pursuing HITRUST CSF assessments. It uses Shared Responsibility Matrices (SRMs) to delineate control ownership between service providers and their customers in cloud and other outsourced environments, and to support control inheritance, whereby a customer can leverage a participating provider's already-implemented and scored controls in its own assessment rather than reimplementing and re-scoring them independently. The program is intended to simplify third-party risk management and reduce duplication of assessment effort. As a HITRUST offering, its scope is limited to the HITRUST CSF and related assurance processes; it is distinct from HIPAA, and inheritance or program participation does not, by itself, satisfy HIPAA obligations, which for covered entities and business associates attach through their defined relationships and applicable rules. Specific SRM contents vary by service provider and by the applicable HITRUST CSF version, which readers should verify against the current HITRUST CSF release.

Why it matters

In cloud and other outsourced environments, one of the most common sources of compliance failure is ambiguity over who is responsible for a given control. When a customer assumes a cloud provider is handling a safeguard that the provider actually expects the customer to configure, gaps can go unnoticed until an assessment or an incident exposes them. The Shared Responsibility and Inheritance Program addresses this problem within the HITRUST context by using Shared Responsibility Matrices to clearly delineate which controls sit with the service provider and which remain with the customer, reducing the guesswork that often accompanies shared infrastructure.

The program also matters because it can reduce duplication of effort. Rather than independently reimplementing and re-scoring controls that a qualifying provider has already put in place, a customer may inherit those controls in its own HITRUST assessment. Major service providers, including AWS and Salesforce, participate in the program, which can streamline both third-party risk management and the assessment process itself for their customers. This can save time and resources for organizations already relying on those providers.

It is important to be precise about scope. The Shared Responsibility and Inheritance Program is a HITRUST offering run by a private organization, and it applies to the HITRUST CSF and related assurance processes. Participation and control inheritance do not, by themselves, establish HIPAA compliance. For covered entities and business associates, HIPAA obligations attach through their defined relationships and the applicable rules, and cannot be delegated away simply by relying on a provider's inherited controls. Organizations should treat inheritance as a way to reduce assessment effort, not as a substitute for their own compliance responsibilities.

Who it's relevant to

Organizations pursuing HITRUST CSF certification

Customers working toward a HITRUST CSF assessment benefit most directly, since inheritance can reduce the number of controls they must implement and score independently. They should still verify which controls are eligible for inheritance under the current CSF version and confirm that responsibilities left to them are fully addressed.

Cloud and managed service providers

Service providers such as AWS and Salesforce that participate in the program publish Shared Responsibility Matrices so their customers can understand control ownership and, where applicable, inherit controls. Participation can be a differentiator for providers serving healthcare and other regulated customers.

Third-party risk management and vendor oversight teams

Teams responsible for evaluating vendors can use SRMs to clarify control ownership in outsourced environments, reducing ambiguity about which safeguards a provider covers. They should remember that a HITRUST-based allocation of controls is distinct from a covered entity's or business associate's HIPAA obligations, which remain governed by the applicable rules and any business associate agreements.

Compliance and security officers in healthcare organizations

Privacy and security officers can leverage the program to streamline assessments, but should be careful not to treat inheritance or program participation as evidence of HIPAA compliance. HIPAA requirements attach through defined relationships and applicable rules, and state law or the HITECH Act may impose additional obligations beyond what the HITRUST CSF addresses.

Inside SRIP

Shared Responsibility Model

A framework that allocates control responsibilities between two or more parties, most commonly between a cloud or hosting service provider and its customer. It clarifies which safeguards each party operates and manages, which is particularly relevant when ePHI is stored or processed in third-party environments. The precise allocation varies by service model and should be documented in the underlying contract or business associate agreement.

Inheritance

A mechanism, used notably within the HITRUST CSF assessment process, by which an organization can rely on the control implementation of another party (such as a service provider) to satisfy some of its own control requirements. Inheritance does not transfer legal accountability; a covered entity or business associate generally remains responsible for HIPAA compliance regardless of controls inherited from a vendor.

HITRUST Inheritance Program

A program offered by HITRUST (a private organization, not a regulator) that allows an assessed entity to inherit scores or control results from another entity's HITRUST CSF assessment. Availability, eligibility, and mechanics depend on the current HITRUST CSF version and program rules, which readers should verify against current HITRUST documentation.

Allocation of Safeguard Responsibilities

Documentation identifying which administrative, physical, and technical safeguards under the HIPAA Security Rule are operated by each party. Because the Security Rule governs only ePHI, shared responsibility arrangements in this context focus on ePHI protections, while Privacy Rule obligations covering PHI in all forms may follow different allocation logic.

Contractual Basis (BAA / Service Agreement)

The written instruments that give effect to shared responsibility. HIPAA obligations flow to vendors through defined relationships and business associate agreements rather than automatically. The BAA and accompanying service documentation should specify each party's duties, though the covered entity or business associate cannot fully delegate away its own compliance accountability.

Scope Boundaries

A clear statement of where one party's responsibility ends and another's begins, typically tied to the layers of a service (for example, underlying infrastructure versus customer-configured application and data settings). Ambiguity in these boundaries is a common source of unaddressed gaps.

Common questions

Answers to the questions practitioners most commonly ask about SRIP.

Does inheriting a control from a cloud provider or service organization mean my organization is no longer responsible for that control?

No. Inheritance generally shifts responsibility for the specific portion of a control that the provider actually operates, but it does not transfer overall accountability to your organization. In a shared responsibility model, some elements of a control are typically performed by the provider while others remain with the customer. As a covered entity or business associate, you generally retain accountability for your compliance obligations, and you should confirm exactly which portions are inherited versus which remain yours. Relying on inheritance without validating the scope can leave gaps in your compliance posture.

If I inherit controls through a HITRUST Shared Responsibility and Inheritance Program, does that make my organization HIPAA compliant?

No. HITRUST is a private organization and the HITRUST CSF is a certifiable control framework; inheritance within a HITRUST program relates to how controls are assessed and shared, not to legal compliance with HIPAA. HITRUST certification and control inheritance do not by themselves establish HIPAA compliance, which is a legal obligation enforced by HHS OCR. Inheritance may help you leverage a provider's assessed controls to support your own assessment, but you remain responsible for meeting the applicable requirements of the Privacy Rule, Security Rule, and other HIPAA rules as they apply to your organization.

How do I identify which controls are eligible for inheritance from a service provider?

Eligibility for inheritance generally depends on the provider having an assessment or certification that covers the relevant controls and on the provider making those results available through an inheritance arrangement. In most cases you review the provider's shared responsibility documentation to map which control elements they operate versus which remain your responsibility. You should verify the scope, the assessment period, and whether the provider's environment matches the services you actually consume, and confirm details against the current HITRUST CSF version and the provider's own documentation.

What documentation should I retain when relying on inherited controls?

It is generally advisable to retain the provider's shared responsibility matrix or documentation, evidence of the provider's applicable assessment or certification, and records showing how you mapped inherited elements to your own control requirements. You should also document the portions of each control that remain your responsibility and how you satisfy them. Because inheritance covers only the provider-operated portions, maintaining clear records of the customer-side responsibilities helps demonstrate your overall compliance posture during audits or assessments.

How should inheritance be reflected in a business associate agreement or vendor arrangement?

HIPAA obligations attach through defined relationships, so where a provider is a business associate, the business associate agreement should reflect the parties' respective responsibilities. Inheritance arrangements typically operate at the assessment and control-documentation level and do not replace the contractual obligations set out in a BAA. You should ensure that the division of responsibilities described in shared responsibility documentation is consistent with the terms of your agreements, and consult the current regulatory text and legal counsel where the allocation of obligations is unclear.

How often should inherited controls be revalidated?

Inherited controls generally reflect the provider's assessment as of a specific period, so they should be revalidated when that assessment expires or is updated, when the services you consume change, or when the provider's environment changes materially. Relying on an outdated assessment can create gaps, so in most cases organizations reconfirm the currency of inherited control results on a periodic basis and verify the details against the provider's latest documentation and the current HITRUST CSF version.

Common misconceptions

Inheriting controls from a service provider transfers HIPAA legal responsibility to that provider.

Inheritance addresses how a control requirement is demonstrated as satisfied; it does not shift legal accountability under HIPAA. A covered entity or business associate generally remains responsible to HHS OCR for its compliance, even where controls are operated by a vendor. Obligations attach through defined relationships and business associate agreements, and cannot be wholly delegated away.

Using a HITRUST-certified provider and inheriting its controls means your organization is HIPAA compliant.

HITRUST is a private organization and HITRUST CSF certification is not a legal requirement; certification or inherited controls do not by themselves establish HIPAA compliance. They may support a compliance program, but the organization must still meet applicable Privacy, Security, Breach Notification, and Enforcement Rule obligations, and may face additional requirements from the HITECH Act or state law.

A shared responsibility model covers all of an organization's HIPAA obligations.

Shared responsibility arrangements in this context typically focus on Security Rule safeguards for ePHI operated within a specific service. They generally do not address the full scope of the Privacy Rule (which covers PHI in all forms, including oral and paper) or all organizational obligations. Anything outside the documented allocation remains the organization's own responsibility.

Best practices

Document the responsibility allocation in writing, mapping each relevant administrative, physical, and technical safeguard to the party that operates it, and ensure this mapping is reflected in the business associate agreement or service contract.

Treat inheritance as evidence of control operation, not as a transfer of accountability; retain your own assessment of whether inherited controls actually meet your applicable HIPAA requirements.

Explicitly identify and assign responsibility for any control gaps that fall outside the provider's scope, giving particular attention to customer-configured settings that vendors typically do not manage.

Verify the specifics of any inheritance program, eligibility, and mechanics against the current HITRUST CSF version and current HITRUST documentation, since these change over time.

Do not treat inherited or certified controls as establishing HIPAA compliance on their own; confirm coverage across the Privacy, Security, and Breach Notification Rules, and check for additional obligations under the HITECH Act or state law.

Reassess the shared responsibility allocation whenever the service model, vendor relationship, or scope of ePHI changes, and obtain updated evidence supporting any controls you continue to inherit.
