    EU AI Act Details

    What It Is

    Regulation (EU) 2024/1689, the EU AI Act, is a comprehensive horizontal regulation establishing a risk-based framework for AI systems across sectors. It prohibits unacceptable-risk practices, regulates high-risk systems via lifecycle controls, mandates transparency for limited-risk AI, and minimally regulates others.

    Key Components

    • **Four-tier risk modelunacceptable, high, limited, minimal.
    • High-risk obligations: risk management (Article 9), data governance (Article 10), documentation, human oversight, cybersecurity (Article 15).
    • GPAI rules (Chapter V): technical docs, systemic risk assessments.
    • Conformity assessments, CE marking, EU database registration; hybrid enforcement via AI Office and national authorities.

    Why Organizations Use It

    Mandatory for EU-market AI; avoids fines up to 7% global turnover. Enhances trust, ensures market access, mitigates risks in high-impact areas like employment, biometrics.

    Implementation Overview

    Phased rollout (6-36 months); inventory/classify AI, build QMS, conduct assessments. Applies to providers/deployers globally if EU outputs used; cross-functional teams needed for documentation, monitoring.

    ISO 27018 Details

    What It Is

    ISO/IEC 27018 is an international code of practice for protecting personally identifiable information (PII) in public clouds acting as PII processors. It augments ISO/IEC 27001 and ISO/IEC 27002 with cloud-specific privacy controls. The risk-based approach integrates into an ISMS, focusing on multi-tenancy and cross-border processing (latest: 2025 edition).

    Key Components

    • ~25–30 additional privacy controls on consent, purpose limitation, data minimization, transparency
    • Maps to ISO 27001 Annex A (93 controls: organizational, people, physical, technological)
    • Principles: accuracy, retention limits, security safeguards, accountability
    • Assessed via ISO 27001 audits; no standalone certification

    Why Organizations Use It

    • Enhances trust, speeds procurement for CSPs
    • Aligns with GDPR Article 28, HIPAA processor duties
    • Mitigates cloud privacy risks, supports insurance
    • Differentiates in competitive markets, builds reputation

    Implementation Overview

    • Gap analysis on existing ISMS, update SoA, policies, contracts
    • Key activities: subprocessor disclosure, breach procedures, training
    • Suits CSPs all sizes/industries; requires ISO 27001 base
    • Audits: stage 1/2, annual surveillance, 3-year recertification
