Assigned Security Responsibility

Also known as: Security Official Designation, HIPAA Security Officer Requirement
Simply put

Assigned Security Responsibility is a HIPAA Security Rule requirement that an organization name a specific person to be in charge of its electronic health data security. This designated security official is responsible for creating and carrying out the policies and procedures needed to protect electronic protected health information (ePHI). The requirement helps ensure that accountability for security is clearly placed with an identified individual rather than left undefined.

Formal definition

Assigned Security Responsibility is an administrative safeguard standard under the HIPAA Security Rule requiring a regulated entity (a covered entity or business associate) to designate a single security official responsible for the development and implementation of the policies and procedures required by the Security Rule. This standard applies specifically to the protection of electronic protected health information (ePHI); it does not, by itself, address PHI in oral or paper form, which falls under the Privacy Rule. The designated official typically oversees the entity's compliance efforts across the administrative, physical, and technical safeguard categories, though the standard establishes the accountability designation rather than prescribing the full scope of the role's tasks. Note that this Security Rule role is distinct from the Privacy Rule's separate requirement to designate a privacy official, and that specific job duties, titles, and reporting structures are determined by each entity. Readers should verify the exact regulatory language against the current text of the HIPAA Security Rule.

Why it matters

Assigned Security Responsibility exists because security accountability that is diffused across an organization tends to become no one's responsibility at all. By requiring a regulated entity to name a single security official, the HIPAA Security Rule ensures there is an identified individual answerable for developing and implementing the policies and procedures that protect electronic protected health information (ePHI). Without this clear designation, gaps in a security program can go unnoticed and unaddressed because no one owns the outcome.

For compliance programs, this designation serves as a foundational anchor. The security official typically becomes the focal point for the entity's broader Security Rule efforts, coordinating across administrative, physical, and technical safeguards. When HHS OCR reviews an entity's security posture, the presence of a designated official and evidence that the role is actively functioning generally signals a more mature and accountable program. Conversely, the absence of a clearly assigned official can undercut an organization's ability to demonstrate that it has taken the required administrative steps.

It is important to recognize what this standard does and does not do. Designating a security official is a required step, but the designation alone does not by itself establish full Security Rule compliance, nor does it guarantee that ePHI is protected against all incidents. It places accountability with a named person; the substantive work of building and maintaining the security program still must be performed. Entities should also note that this Security Rule role is separate from the Privacy Rule's distinct requirement to designate a privacy official.

Who it's relevant to

Security and Compliance Officers
Individuals who hold or are being considered for the designated security official role should understand that they carry accountability for developing and implementing the Security Rule's required policies and procedures for ePHI. They typically coordinate compliance work across administrative, physical, and technical safeguards, though each entity defines the specific duties, title, and reporting structure of the position.
Covered Entities and Business Associates
Any regulated entity subject to the HIPAA Security Rule must designate a security official. This includes both covered entities and business associates. Organizations should document who holds the role to demonstrate that this administrative safeguard has been met, keeping in mind that the designation is one required step and does not by itself constitute full Security Rule compliance.
Privacy Officers and Legal Teams
Because the Security Rule's security official is distinct from the Privacy Rule's separately required privacy official, privacy officers and legal teams should ensure both roles are clearly assigned and not conflated. They may also need to consider whether state law or other frameworks impose additional requirements beyond the HIPAA baseline.
Auditors and Assessors
Those evaluating an organization's HIPAA posture generally look for evidence that a security official has been designated and that the role is actively functioning. Assessors should confirm the designation against the current text of the Security Rule and recognize that documenting an assigned official supports, but does not alone prove, an effective security program.

Inside Assigned Security Responsibility

Standard Under the Security Rule
Assigned Security Responsibility is an administrative safeguard standard within the HIPAA Security Rule, which governs the protection of electronic protected health information (ePHI). It requires that a specific individual be designated as responsible for the development and implementation of the required security policies and procedures.
Designated Security Official
The standard calls for identifying a security official who bears responsibility for the covered entity's or business associate's Security Rule compliance efforts. This is typically a named individual accountable for the security program, as distinguished from the privacy official designated under the Privacy Rule, though in some smaller organizations one person may hold both roles.
Scope Limited to ePHI
Because this is a Security Rule standard, its focus is on electronic protected health information. It does not, by itself, address PHI in oral or paper form, which falls under the broader Privacy Rule and that rule's own designation of a privacy official.
Applies to Covered Entities and Business Associates
The obligation to assign security responsibility generally applies to covered entities and, through the applicability of the Security Rule, to business associates. Obligations for subcontractors typically flow through business associate agreements rather than attaching automatically to any vendor that touches data.
Accountability Function
The standard centralizes accountability by ensuring a single point of responsibility exists for overseeing the administrative, physical, and technical safeguards mandated by the Security Rule, supporting coordinated implementation and oversight of the security program.

Common questions

Answers to the questions practitioners most commonly ask about Assigned Security Responsibility.

Is Assigned Security Responsibility just a formality that can be shared across a whole committee?
No. The Security Rule's administrative safeguard for Assigned Security Responsibility generally requires that a covered entity or business associate identify a specific security official who is responsible for developing and implementing the required policies and procedures. While that official can and typically does rely on a team, committee, or delegated staff to carry out the work, the accountability is generally intended to rest with an identified individual rather than being diffused across a group with no single point of responsibility. You should confirm the exact requirement language against the current regulation.
Does having a HITRUST certification or naming a security officer for HITRUST purposes satisfy this HIPAA requirement?
Not by itself. HITRUST is a private organization and the HITRUST CSF is a certifiable control framework; certification is not a legal requirement and does not by itself establish HIPAA compliance. Assigning security responsibility as part of a HITRUST effort may overlap with the HIPAA Security Rule's Assigned Security Responsibility standard, but the HIPAA obligation is a distinct regulatory requirement enforced by HHS OCR. You should evaluate whether your assignment meets the HIPAA standard independently and verify against current guidance.
Can the same person serve as both the HIPAA security official and the Privacy Rule privacy official?
In many organizations one person holds both roles, and the rules do not generally prohibit this. However, the two roles arise under different rules: the Assigned Security Responsibility standard falls under the Security Rule, which addresses ePHI, while the privacy official responsibility arises under the Privacy Rule, which covers PHI in all forms including oral and paper. Whether combining the roles is appropriate typically depends on the size, complexity, and resources of the entity.
How should we document that we have met the Assigned Security Responsibility requirement?
Entities generally document the assignment in writing, for example by identifying the security official by role or title within their security policies and procedures and retaining supporting records. Because this is an administrative safeguard, maintaining documentation that shows who holds the responsibility and what their duties are is typically important for demonstrating compliance during an OCR inquiry or audit. Confirm any specific documentation retention expectations against the current regulation.
Does a business associate need to assign security responsibility, or only the covered entity?
Business associates are generally directly subject to the Security Rule's administrative safeguards, including the Assigned Security Responsibility standard, with respect to the ePHI they handle. This obligation typically applies independently of, and in addition to, any commitments made in a business associate agreement. Subcontractors that create, receive, maintain, or transmit ePHI on behalf of a business associate may have comparable obligations. Verify the current regulatory text for how these requirements apply to your role.
What should the assigned security official actually be responsible for day to day?
The security official is generally responsible for developing, implementing, and maintaining the security policies and procedures required under the Security Rule, which may include overseeing the risk analysis process, coordinating administrative, physical, and technical safeguards, and managing responses to security incidents. The precise scope typically varies with the entity's size and complexity, and the official may delegate specific tasks while retaining overall accountability. Note that this role addresses the Security Rule's ePHI safeguards and does not by itself cover Privacy Rule or Breach Notification Rule obligations, which may involve additional or separate responsibilities.

Common misconceptions

The security official and the privacy official must always be two different people.
The Security Rule requires designation of a security official, and the Privacy Rule separately requires a privacy official. These are distinct roles with distinct scopes, but the regulations generally do not prohibit one individual from serving in both capacities, which is common in smaller organizations. Readers should confirm role assignments against the current regulatory text.
Assigning a security official on its own makes an organization compliant with the Security Rule.
Designating a security official satisfies only this one administrative standard. Full Security Rule compliance requires implementing the full set of administrative, physical, and technical safeguards, including both required and addressable implementation specifications. Naming an official does not guarantee compliance or prevent all breaches.
This standard covers responsibility for all PHI in the organization.
As a Security Rule standard, Assigned Security Responsibility is focused on electronic PHI. Protection of PHI in oral and paper forms is addressed under the Privacy Rule and its designated privacy official, so this standard should not be treated as covering PHI in all forms.

Best practices

Formally designate a named security official in writing, and clearly document the scope of their authority and responsibilities for the Security Rule compliance program.
Clarify in policy whether the security official and privacy official roles are held by the same or different individuals, and define how the two coordinate given their distinct scopes.
Ensure the designated security official has sufficient authority, resources, and organizational access to develop and implement the required administrative, physical, and technical safeguards.
Extend the designation to business associates as applicable, and address related responsibilities through business associate agreements rather than assuming obligations attach automatically to every vendor.
Review and update the designation whenever there is a personnel change, so accountability for ePHI protection is never left vacant.
Confirm role definitions and related requirements against the current text of the Security Rule, and note that state law or the HITECH Act may impose additional obligations beyond this standard.
