MASTER ISA/IEC 62443 Essential Security Framework for Industrial Systems

This book is intended for cybersecurity professionals and students, industrial automation, GRC, and critical infrastructure who seek operational mastery of the ISA/IEC 62443 framework for OT/IT environments. The content delivers direct application of international requirements, with validated practical examples in industrial plants, utilities, energy, manufacturing, oil & gas, and highly regulated environments. Learn how to structure technical inventories with Tenable.ot, Nozomi, Claroty, and Forescout, segment networks into zones and conduits, apply hardening to PLCs, SCADA, DCS, orchestrate industrial firewalls, DMZ, proxies, and protect protocols such as Modbus, DNP3, OPC UA, Profibus, EtherNet/IP. Implement inventory automation, Python and PowerShell scripts, asset integration via CMDB, advanced access control, RBAC, MFA, credential management and secure rotation, orchestration of industrial SOC, SIEM, SOAR (Splunk, XSOAR, QRadar), PDCA risk analysis, vulnerability management, industrial backup, and firmware update.

Execute OT/IT/Cloud integration, microsegmentation, IIoT onboarding, compliance with NIST, NERC CIP, ISO, LGPD, GDPR, technical auditing, and compliance automation. Master strategies for professional certifications, audit preparation, and leadership of critical operations aligned to global standards.

Includes:

• Advanced structuring of zones, conduits, and OT/IT segmentation

• Industrial asset management, automated inventory, and CMDB integration

• Implementation of industrial SOC, SIEM, SOAR, and forensic analysis

• Access control, MFA, RBAC, remote lockdown, and PLC hardening

• Protection of industrial protocols: Modbus, DNP3, OPC UA, Profibus, EtherNet/IP

• Credential policies, backup, firmware update, and IIoT onboarding

• Compliance and technical auditing with NIST, ISO, NERC CIP, LGPD, GDPR

• Incident response automation, scripts, microsegmentation, and cloud integration

By the end, you will be able to lead industrial security projects, manage ISA/IEC 62443 certification, elevate operational maturity, and consolidate critical environments under the highest standards of automation and international compliance.
