Assigned Security Responsibility: Naming a security official and giving the role real authority

45 CFR 164.308(a)(2) covers assigned security responsibility. In most assessments the control itself is present and the record proving it is not, which is why this requirement produces findings at organizations that are, in practice, doing the work.

What the rule says

Standard: Assigned security responsibility. Identify the security official who is responsible for the development and implementation of the policies and procedures required by this subpart for the covered entity or business associate.

That is the text of 45 CFR 164.308(a)(2). Read it closely: it describes an outcome to achieve, not a product to buy, which is why two practices of the same size can satisfy it in different ways and both be right.

This is a standard, and a standard is met in full: 45 CFR 164.306(c) requires a covered entity or business associate to comply with the applicable standards.

What this looks like in practice

In an assessment, 45 CFR 164.308(a)(2) is not one question. It resolves into several, and each one is really asking for different evidence. These are among the questions asked about it:

• Has the organization formally assigned an individual responsible for developing, implementing, and maintaining its security program?
• Has the organization established a formal security governance structure with defined accountability and documented involvement of executive leadership or the governing body in security oversight?
• Has the organization documented the responsibilities of security and compliance roles, including a job description for the individual accountable for the security program?

Ownership usually sits with the security official, though the evidence is often produced by someone else, which is where the trail breaks. A control that works but has no owner tends to stop working the month the person who quietly maintained it changes roles.

Who this applies to

Every covered entity and every business associate, at any size. 45 CFR 164.306(b) allows flexibility of approach, so a two-provider practice and a hospital system may implement this differently and both comply. What flexibility does not allow is skipping the decision: the smaller the organization, the more the written reasoning carries the weight, because there is no scale of operation to make the control self-evident.

Building it, in order

These steps are one way to meet it, drawn from our question bank. Unless a step names a provision, the Security Rule does not require that particular measure: 45 CFR 164.306(b)(1) lets you use any security measures that allow you to reasonably and appropriately implement the standards and implementation specifications, chosen with the factors in 45 CFR 164.306(b)(2).

The sequence below is the order that produces evidence as a by-product rather than as a separate documentation exercise:

1. Designate a named individual as the security officer accountable for the security program.
2. Document the appointment and the authority delegated to the role.
3. Ensure the role has sufficient standing and resources to carry out its responsibilities.
4. Communicate the designation to the workforce.
5. Establish a security governance charter or policy approved by executive leadership or the governing body.
6. Define the decision-making authority and accountability for security risk decisions.

Where else this maps

The questions behind 45 CFR 164.308(a)(2) also map to HHS 405(d) HICP (2023 Edition) CSP 10 and NIST SP 800-66 Rev. 2 5.1.2, which are voluntary guidance rather than law; following them does not by itself establish compliance with any law. That matters for scoping: the same evidence can be written once and referenced from each, rather than rewritten per framework.

Evidence an assessor asks for

For this requirement the evidence types that satisfy it are policy and record. The distinction matters more than it looks: a policy states what you intend to do, a procedure states how, and a record proves it happened on a date. Auditors ask for all three, and a practice that has written the first two often has nothing for the third.

Date every document and keep the superseded versions. 45 CFR 164.316(b)(2)(i) requires the documentation 164.316(b)(1) calls for (the Security Rule policies and procedures, and the written record of any action, activity or assessment the Security Rule requires to be documented) to be retained for six years from the date of its creation or the date when it last was in effect, whichever is later, so a policy you replaced two years ago is still part of the record.

Where this usually goes wrong

In our question bank this is weighted Critical: a gap here is raised as a critical finding (a partial answer as high). The usual cause of a gap is drift: the control was implemented once, the environment changed, and nothing re-checked it. A dated review on a fixed cadence is cheaper than the remediation.

What to do about it

• Produce the evidence, not the intention. For 45 CFR 164.308(a)(2) that means a signed, dated policy with a named owner and a review date and dated records of each occurrence, not a description of the process. If the only evidence is that someone knows how this works, you have a practice and not a record.
• Put a name on it. Your security official should be recorded as the owner. Where the work is done by someone else, say so in the document: the split between who owns it and who performs it is where the trail usually breaks. A control with no owner stops working the month the person who quietly maintained it changes roles, and nobody notices.
• Review it on a fixed date, not when you remember. In our question bank this is weighted Critical: a gap here is raised as a critical finding (a partial answer as high). Put the review on the calendar with an owner, and keep the dated output of each one.
• There is no documented-alternative route for the requirement itself. It is required (45 CFR 164.306(d)(2) for a specification, 164.306(c) for a standard), so a risk-based decision not to meet it is not available. How you meet it is yours to choose under 45 CFR 164.306(b); the measures in this post are examples, not the rule's text.

If 45 CFR 164.308(a)(2) is new to you, the useful first step is not a policy template. It is writing down what you already do, dating it, and naming an owner. That turns an undocumented practice into evidence, and it usually reveals the real gap.
