Assigned Security Responsibility 45 CFR 164.308(a)(2)
The Assigned Security Responsibility standard requires every covered entity and business associate to designate a single, named Security Official accountable for the entire HIPAA Security Rule program.
What the regulation requires
There is no implementation specification under this standard. The entire requirement is that one named, identifiable individual owns the program. For small practices that often means the practice administrator with vCISO support; for larger organizations it is a dedicated CISO or HIPAA Security Officer.
Implementation specifications
Designate a Security Official
Single named individual with documented authority over Security Rule policy development and implementation. Responsibility may be delegated but accountability cannot. (164.308(a)(2))
How Petronella implements this safeguard
Every Petronella HIPAA engagement maps 45 CFR 164.308(a)(2) to documented evidence in your environment. This is what that looks like in practice for the assigned security responsibility standard:
- Petronella vCISO services provide a credentialed Security Official for practices that do not have one in-house, with documented appointment letter and scope.
- We sit on your Security Committee, sign the Risk Analysis as the responsible official, and own the documentation chain.
- If you have an internal Security Official, we co-sign and provide gap-coverage during PTO, parental leave, or transition.
- Quarterly review meetings with the Security Official to keep the risk register and remediation roadmap current.
Built on top of ComplianceArmor for documentation, training records, and BAA inventory, with optional HIPAA managed IT services for the technical safeguard layer and vCISO services for the named Security Official role.
Where most practices fall short
OCR resolution agreements, HHS audit reports, and our own engagements show the same handful of gaps under 45 CFR 164.308(a)(2). We surface these before they become a finding.
- Role is unfilled or held by a generic title ("IT") rather than a named person, which OCR cited in the $2.5 million CardioNet settlement.
- Security Official is named but has no documented authority, no time allocated, and no budget.
- Security Official does not receive copies of incidents, audit reports, or risk findings.
- When the Security Official leaves, no successor is named for months, leaving the program without an owner.
