ISO 37001 Details
What It Is
ISO 37001 is the international standard for Anti-Bribery Management Systems (ABMS), providing certifiable requirements to prevent, detect, and respond to bribery. It applies to all organization types and sizes, focusing on direct/indirect bribery involving personnel and third parties via a risk-based, proportionate approach structured around the Harmonized Structure (HS) and PDCA cycle.
Key Components
- Clauses 4-10 cover context, leadership, planning, support, operations, evaluation, and improvement.
- Core elements: anti-bribery policy, risk assessments, due diligence, financial/non-financial controls, training, reporting, audits.
- Built on proportionality to bribery risks; optional third-party certification with annual surveillance.
Why Organizations Use It
- Mitigates legal risks (e.g., FCPA, UK Bribery Act) via evidentiary "reasonable steps".
- Drives efficiencies (up to 15% compliance cost reduction), reputational trust, ESG alignment.
- Enables market access, stakeholder confidence in high-risk sectors like extractives, construction.
Implementation Overview
- Phased: gap analysis, risk assessment, control design, training, audits, certification.
- Scalable for SMEs to multinationals; integrates with ISO 9001/27001; 6-12 months typical timeline.
IEC 62443 Details
What It Is
IEC 62443 is the international consensus-based series of standards for securing Industrial Automation and Control Systems (IACS). It provides a comprehensive, risk-based framework tailored to OT environments, emphasizing lifecycle security from governance to components.
Key Components
- Four groupings: General (-1), Policies (-2), System (-3), Components (-4).
- Seven Foundational Requirements (FR1-7) like authentication, integrity, and availability.
- Zones/conduits model, Security Levels (SL0-4) with SL-T/C/A triad.
- ~127 CSMS requirements; supported by ISASecure modular certifications (SDLA, CSA, SSA).
Why Organizations Use It
- Mitigates OT-specific risks (safety, availability, legacy systems).
- Meets regulatory references (e.g., NIS-2, NERC CIP alignments).
- Enables shared responsibility, supply chain assurance, reduced downtime.
- Builds stakeholder trust via certifications, competitive edge in procurement.
Implementation Overview
Phased: CSMS governance (-2-1), risk assessment/zoning (-3-2), controls (-3-3/-4-2). Applies to critical infrastructure globally; requires OT expertise, audits for certification. (178 words)
