EU DORA DORA vs ISO 27001

Use ISO 27001 as the management system backbone - then add DORA-specific reporting, RoI, and resilience testing.

Map controls and evidence once, generate two audit views.

Overview

ISO/IEC 27001:2022 is an information security management system (ISMS) standard that helps you run a repeatable risk and control program with auditability. DORA is an EU regulation that adds prescriptive operational resilience obligations for financial entities: structured incident reporting, ICT third-party dependency transparency (RoI), oversight expectations, and advanced testing (including TLPT in certain cases). The efficient approach is: ISO 27001 for the management system, DORA for the sector-specific "must ship" capabilities.

Section 1

What maps well (ISO 27001 as the operating system)

ISO 27001 gives you the governance spine: risk assessment, control operation, internal audit, management review, and continual improvement.

Those mechanisms translate well to DORA's expectation that ICT risk management is systematic, measured, and evidence-backed.

  • Risk management lifecycle: risk assessment, treatment plans, and acceptance decisions.
  • Policy system and control objectives with evidence trails (procedures, logs, test results).
  • Assurance cadence: internal audits, corrective actions, and management review outputs.
Section 2

Where DORA goes beyond ISO 27001 (DORA-specific deliverables)

DORA includes operational resilience deliverables that are not "automatic" outcomes of an ISMS audit.

You can still leverage ISO controls, but you must implement DORA-specific workflows, templates, and supervisory artifacts.

  • Major incident reporting: classification logic + staged regulatory reports with time limits and specified content (RTS/ITS).
  • Register of information: exportable RoI templates for ICT third-party contractual arrangements (Article 28 + ITS 2024/2956).
  • Third-party contracting clauses and subcontracting assessment (RTS 2024/1773 + RTS 2025/532).
  • Advanced testing: scenario-based testing and TLPT readiness where applicable (TLPT RTS and ECB TIBER-EU framework context).
Section 3

Practical mapping approach (build once, audit twice)

Build a control-to-obligation mapping matrix and reuse evidence where it truly matches DORA intent and outputs.

Treat gaps as product work: reporting pipeline, RoI exporter, testing program - and track them like engineering deliverables.

  • Map ISO controls -> DORA requirements and Level 2 RTS/ITS outputs where relevant.
  • Define DORA-only controls (RoI exports, regulator reporting templates/time limits, critical provider oversight readiness).
  • Create an evidence index: every DORA requirement points to a system-of-record artifact and a validation/test.
Section 4

Evidence pack strategy (what to show, not just what to say)

ISO audits often accept "process + sampling". DORA supervision often asks for operational proof under stress: what happens during outages, what you report, and how you know the supply chain.

Upgrade your evidence pack to be exportable and reproducible.

  • Incident reporting: classification decision logs + submitted reports + submission receipts + post-incident learning closure.
  • Third-party: clause mapping (RTS 2024/1773), subcontracting assessments (RTS 2025/532), and exit plan feasibility tests.
  • RoI: validated ITS exports (B_01-B_07) with stable identifiers and consolidation consistency.
  • Testing: results from resilience testing and TLPT readiness artifacts (where applicable).
