Accountability sits across cybersecurity, legal, compliance, enterprise risk, procurement, IT, and executive leadership because DORA is a cross-functional resilience requirement. If cybersecurity is left solely responsible, the operating model usually lacks the business engagement needed to maintain accurate evidence and remediation ownership.
Why This Matters for Security Teams
DORA readiness fails when accountability is treated as a paperwork exercise instead of an operating model issue. The regulation expects firms to evidence who owns resilience, who remediates control gaps, and who can prove testing, incident response, and third-party oversight are working. That makes accountability broader than security alone and more operational than many organisations initially assume, as reflected in the EU Digital Operational Resilience Act (DORA) and NHIMG’s Ultimate Guide to NHIs — Regulatory and Audit Perspectives.
The practical failure mode is simple: cybersecurity identifies the gap, but legal, procurement, IT, and business owners do not carry remediation through to closure. That creates weak evidence chains, delayed fixes, and unclear sign-off on residual risk. Under DORA, those weaknesses become audit findings, not just internal friction. In practice, many security teams encounter accountability breakdowns only after a control failure has already affected evidence quality or remediation deadlines.
How It Works in Practice
Accountability under DORA should be mapped to the control lifecycle, not to a single team. Cybersecurity typically owns technical control design and monitoring, compliance translates the requirement into evidence expectations, legal interprets contractual and regulatory exposure, procurement ensures supplier obligations are enforceable, IT executes remediation, and executive leadership resolves priority conflicts. That model aligns with the intent of NIST SP 800-53 Rev 5 Security and Privacy Controls, which expects controls to be assigned, implemented, assessed, and monitored through defined ownership.
A workable approach is to define three layers of accountability:
-
Control owner: accountable for design and ongoing effectiveness.
-
Evidence owner: accountable for producing and retaining proof for audits, testing, and incidents.
-
Remediation owner: accountable for closing findings within agreed deadlines.
For third-party risk, the same structure should extend to vendors and critical service providers, because DORA expects operational resilience across the supply chain. For non-human identities and access pathways, evidence must show who approved privileges, who reviewed them, and who can revoke them when risk changes. NHIMG’s research on the DeepSeek breach shows how quickly exposed credentials and uncontrolled access can turn into broader resilience concerns when ownership is unclear. These controls tend to break down in decentralised organisations where remediation depends on informal follow-up and no one has explicit authority to force closure.
Common Variations and Edge Cases
Tighter accountability often increases coordination overhead, so organisations must balance faster decision-making against the administrative cost of assigning owners at every layer. There is no universal standard for this yet, but current guidance suggests that firms should avoid both extremes: security as the sole owner, or shared ownership so diffuse that nobody is answerable.
In smaller organisations, one person may wear multiple hats, but the roles should still be distinct in the control register and evidence trail. In complex groups, accountability should be anchored at the business service or process level, then cascaded to function owners. For outsourced environments, contracts should define who supplies logs, attestations, test results, and remediation timelines. Where DORA readiness fails most often is not in the control itself, but in the gap between policy language and the named person who must act when the evidence is missing.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 and CSA MAESTRO address the attack and risk surface, while NIST CSF 2.0, NIST AI RMF and NIST Zero Trust (SP 800-207) set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST CSF 2.0 | GV.RR-01 | DORA readiness depends on clear roles and responsibilities across functions. |
| NIST AI RMF | GOVERN | Governance clarifies accountability, escalation, and oversight for operational risk. |
| NIST Zero Trust (SP 800-207) | Section 4.1 | Zero trust relies on explicit policy enforcement and verified ownership of access decisions. |
| OWASP Non-Human Identity Top 10 | NHI-01 | Non-human identities need defined ownership to avoid orphaned access and evidence gaps. |
| CSA MAESTRO | GOV-1 | Agentic and automated workflows need governance to ensure human accountability remains clear. |
Tie access and control ownership to explicit policy enforcement and continuous verification.
