ISA/IEC 62443-3-3 Mining Implementation Checklist

ISA/IEC 62443-3-3 defines the security program requirements for Industrial Automation and Control Systems (IACS), specifying 12 foundational security capability categories—including asset management, secure configuration, vulnerability management, incident response, and security awareness—that must be implemented according to assigned Security Levels (SLs). In the mining context, this standard is adapted to address sector-specific challenges: geographically dispersed assets (e.g., open-pit or underground sites with satellite or LTE backhaul), high reliance on OT/IT convergence (e.g., IIoT sensors feeding AI-driven grade control), and stringent safety-integrity intersections (e.g., where cybersecurity failures could trigger physical hazards like conveyor overloads or ventilation shutdowns). The Mining Implementation Checklist operationalizes these requirements by mapping each 62443-3-3 capability to actionable, auditable items—such as verifying role-based access controls on PLC programming interfaces, validating air-gapped backup procedures for critical DCS controllers, or confirming firmware signing and integrity verification for autonomous haul truck ECUs. It further incorporates mining-relevant risk criteria (e.g., consequence weighting for loss of blast timing synchronization or tailings dam monitoring integrity) and integrates with broader mine lifecycle frameworks like ISO 45001 (occupational health & safety) and ISO 27001 (information security management), enabling unified governance across safety, security, and reliability domains.
