What is the primary objective of DORA?

DORA's primary objective is to strengthen the digital operational resilience of the EU financial sector against ICT disruptions, including cyberattacks, system failures, and third-party risks. Regulation (EU) 2022/2554 mandates proactive ICT risk management, incident reporting, resilience testing, third-party oversight, and information sharing for 20 types of financial entities and critical ICT third-party providers (CTPPs), which applied fully from January 17, 2025.

Who is legally or professionally required to comply with DORA?

DORA legally requires compliance from approximately 22,000 EU-regulated financial entities across 20 types, including credit institutions, insurance undertakings, investment firms, payment institutions, and crypto-asset service providers, plus designated critical ICT third-party providers (CTPPs). CTPPs, such as cloud and data analytics firms, face direct ESA oversight, with ~1,000+ providers in the EU landscape that were identified for potential designation by end-2025.

Does DORA require an external audit or third-party certification?

DORA does not mandate external audits or third-party certification but requires independent execution of digital operational resilience testing, including risk-based annual basic tests and triennial threat-led penetration testing (TLPT) for critical entities. Results must be reported to authorities, with proportionality allowing internal or external testers; ESAs validate TLPT scopes via RTS published July 17, 2024.

How often should an assessment for DORA be performed?

DORA mandates annual basic digital operational resilience testing, such as vulnerability assessments, for all in-scope entities, with triennial advanced threat-led penetration testing (TLPT) for critical or designated entities. ICT risk management frameworks require annual reviews, tailored by proportionality to entity size, complexity, and risk exposure, per Batch 1 RTS/ITS from January 17, 2024.

What are the consequences of non-compliance with DORA?

Non-compliance with DORA incurs administrative fines up to 2% of total global annual turnover for firms and up to €5 million or 10% of annual salary for individuals, imposed by ESAs or competent authorities. CTPPs face annual oversight fees up to €1 million, with remediation enforced through strict RTS on ICT risks, incidents, testing, and third-party policies.

Can DORA be mapped to other international frameworks?

DORA cannot be directly mapped to other international frameworks within its standalone scope, as it establishes EU-specific harmonized rules for financial sector ICT resilience. While pre-DORA guidelines like EBA 2019 ICT rules provide a foundation for larger entities, DORA's mandatory RTS/ITS (Batches 1 and 2, 2024) demand unique implementations for incident classification, TLPT, and CTPP oversight.

What is the first step to begin implementing DORA?

The first step to implement DORA is conducting a gap analysis against the ICT risk management framework RTS published January 17, 2024, to identify, assess, and prioritize ICT risks aligned with business objectives. Establish management body oversight, map third-party dependencies, and define proportionality-based controls, including recovery time objectives under 4 hours for critical services, which was required ahead of the January 17, 2025 deadline.

What is the primary objective of ISO 27017?

ISO 27017 provides cloud-specific implementation guidance for ISO 27002 controls and introduces seven additional cloud-focused controls (CLD.6.3.1, CLD.8.1.5, CLD.9.5.1, CLD.9.5.2, CLD.12.1.5, CLD.12.4.5, CLD.13.1.4). Published in 2015, it addresses shared responsibilities between cloud service providers (CSPs) and cloud service customers (CSCs), covering multi-tenancy segregation, virtual machine hardening, asset removal/return, administrative operations, customer monitoring, and network alignment in public, private, and hybrid clouds.

Who is legally or professionally required to comply with ISO 27017?

No organization is legally required to comply with ISO 27017, as it is a voluntary code of practice. Professionally, CSPs and CSCs with significant cloud footprints adopt it to demonstrate due diligence, especially in regulated sectors or procurement demanding cloud security assurance; ~94% of organizations use cloud services, with 61% reporting incidents.

Does ISO 27017 require an external audit or third-party certification?

ISO 27017 does not support standalone third-party certification or require external audits. It is implemented within an ISO 27001 ISMS, with its 37 extended controls and seven CLD controls assessed during ISO 27001 audits by accredited certification bodies.

How often should an assessment for ISO 27017 be performed?

ISO 27017 assessments occur as part of annual ISO 27001 surveillance audits and triennial re-certification. Controls must align with ongoing ISMS risk assessments and management reviews to address cloud changes.

What are the consequences of non-compliance with ISO 27017?

Non-compliance with ISO 27017 carries no direct legal penalties, as it is voluntary. Indirect risks include heightened breach exposure from unaddressed cloud risks (e.g., multi-tenancy failures), failed procurements, regulatory scrutiny under data laws, and loss of competitive edge for CSPs.

Can ISO 27017 be mapped to other international frameworks?

Yes, ISO 27017 maps directly to ISO 27001 Annex A and ISO 27002 controls. Its cloud guidance integrates with ISMS structures; organizations map its seven CLD controls to broader frameworks via risk-based Statements of Applicability, though specifics depend on scope.

What is the first step to begin implementing ISO 27017?

Conduct a cloud-specific risk assessment within your ISO 27001 ISMS to identify applicable controls. Define CSP/CSC shared responsibilities (CLD.6.3.1), scope cloud services, and update the Statement of Applicability to include the 37 extended and seven CLD controls.
