DORA Details
What It Is
DORA, formally Regulation (EU) 2022/2554, is an EU-wide regulation bolstering digital operational resilience for the financial sector against ICT disruptions like cyberattacks and system failures. Applicable to 20 financial entity types and critical third-party providers (CTPPs) across 27 member states from January 17, 2025, it employs a risk-based, proportional approach to shift from reactive to proactive resilience strategies.
Key Components
- **ICT Risk Management FrameworksIdentification, mitigation, annual reviews integrated with business objectives.
- **Incident Reporting4-hour initial alerts, 72-hour updates, 1-month root-cause analysis for major incidents.
- **Resilience TestingAnnual basic tests; triennial threat-led penetration testing (TLPT) for critical functions.
- **Third-Party Risk OversightDue diligence, contractual clauses, ESAs direct supervision of CTPPs. Compliance via ESAs technical standards; penalties up to 2% global turnover.
Why Organizations Use It
Mandated for ~22,000 entities, DORA ensures legal compliance amid rising threats (74% ransomware incidents). It enhances systemic resilience, fosters transparency, builds stakeholder trust, and drives cybersecurity innovation, mitigating risks like 2024 CrowdStrike outage.
Implementation Overview
Gap analyses, framework development, testing programs, vendor monitoring. Tailored by size/complexity; no certification but authority reporting/audits required. Key activities: risk assessments, training, tool integration for ~12-18 months typical rollout.
ISO 27018 Details
What It Is
ISO/IEC 27018 is a code of practice extending ISO 27001 and ISO 27002 for protecting personally identifiable information (PII) in public clouds where providers act as PII processors. Its primary purpose is to provide privacy-specific controls and guidance for cloud environments, focusing on multi-tenancy, cross-border processing, and processor obligations. It uses a risk-based, control-oriented approach integrated into an Information Security Management System (ISMS).
Key Components
- Core pillars: transparency, accountability, consent, purpose limitation, data minimization, security safeguards.
- Approximately 25–30 additional privacy controls mapped to ISO 27001 Annex A themes.
- Built on ISO 27002 guidance; not standalone but assessed during ISO 27001 audits.
- Certification via accredited bodies as ISMS extension, with 3-year validity and annual surveillance.
Why Organizations Use It
Drives customer trust, accelerates procurement, aligns with GDPR/HIPAA, reduces risk via subprocessors disclosure and breach notification. Offers competitive differentiation for CSPs and favorable cyber insurance terms.
Implementation Overview
Layer onto existing ISO 27001 ISMS; conduct gap analysis, update Statement of Applicability, implement controls like encryption and logging. Suited for CSPs of all sizes; requires third-party audits.
