OT/ICS Security Assessment Framework — IEC 62443 Edition

OT/ICS Security Assessment Framework — IEC 62443 Edition

The Cybersecurity Assessment Every Critical Infrastructure Operator Should Perform.

A professionally developed Operational Technology (OT) and Industrial Control System (ICS) security assessment framework designed to evaluate cybersecurity controls across manufacturing, logistics, utilities, critical infrastructure, and industrial environments.

Built using IEC 62443, NIST SP 800-82, CISA ICS Security Guidance, and Purdue Model architecture principles, this assessment helps organisations identify weaknesses before they become operational disruptions, safety incidents, or ransomware events.

Unlike generic IT security assessments, this framework recognises that OT environments prioritise:

Safety → Availability → Integrity → Confidentiality

and evaluates controls accordingly.

Why This Assessment Matters

Many organisations have mature IT security programmes.

Very few have mature OT security programmes.

The result?

⚠ Ransomware reaches production systems

⚠ Safety systems become exposed

⚠ Legacy PLCs remain unpatched

⚠ Vendor access becomes unmanaged

⚠ IT incidents become OT incidents

⚠ Production downtime becomes unavoidable

This assessment helps organisations identify and prioritise OT cybersecurity improvements before a real incident occurs.
