ISO 27701 Details
What It Is
ISO/IEC 27701:2025 is an international certification standard extending ISO/IEC 27001 to establish a Privacy Information Management System (PIMS). It provides requirements and guidance for managing privacy risks in processing personally identifiable information (PII) using a risk-based, PDCA (Plan-Do-Check-Act) approach.
Key Components
- Clauses 4–10 mirror ISO 27001 with privacy extensions.
- **Annex AControls for PII controllers (e.g., consent, DSARs).
- **Annex BControls for PII processors (e.g., contracts, sub-processors).
- Mappings to GDPR (Annex D) and other standards.
- Built on ISO 27000 family; supports standalone or integrated certification.
Why Organizations Use It
- Demonstrates accountability for GDPR/POPIA/LGPD compliance.
- Reduces privacy risks and builds supply-chain trust.
- Enables procurement differentiation and regulatory evidence.
- Enhances reputation via auditable processes.
Implementation Overview
- Phased: scope, gap analysis, controls, audits.
- Applies to all PII-processing organizations.
- 6–12 months typical; requires internal audits, Statement of Applicability, certification by accredited bodies with 3-year cycles and surveillance.
MAS TRM Details
What It Is
MAS Technology Risk Management (TRM) Guidelines (revised January 2021) are supervisory guidance issued by the Monetary Authority of Singapore for financial institutions. They provide a principles-and-outcomes-based framework focused on technology and cyber risk governance, controls, and resilience to protect confidentiality, integrity, and availability (CIA) of systems and data.
Key Components
- 15 main sections covering governance, risk frameworks, secure development, IT operations, resilience, access controls, cryptography, cyber defence, assessments, and audit.
- Synthesised into 12 core principles like board accountability, asset management, third-party oversight, and defence-in-depth.
- Proportional implementation based on risk profile; no fixed controls but minimum expectations (e.g., annual pen testing for internet-facing systems).
Why Organizations Use It
- Essential for MAS-supervised FIs to demonstrate sound practices during supervision.
- Enhances cyber resilience, reduces incident impact, builds customer trust.
- Supports digital transformation while mitigating systemic risks.
Implementation Overview
- Risk-based rollout: asset inventories, control mapping, testing regimes.
- Applies to all Singapore FIs; scalable by size/complexity.
- No formal certification; evidenced through audits and supervisory reviews. (178 words)
