ICS Cybersecurity Mindset

Securing an industrial environment requires understanding both cybersecurity and operational processes.

An ICS security professional must consider how security controls affect production, safety, reliability, availability, engineering workflows, and the physical process being controlled. SANS emphasizes understanding what normal ICS operations look like, identifying vulnerabilities, building architectural choke points, and developing the ability to detect and respond to security events.

A strong ICS security mindset connects:

Understand the Process → Map the Architecture → Identify Dependencies → Protect the Environment → Monitor Activity → Respond to Incidents → Maintain Resilience

This approach helps candidates think beyond traditional IT security controls and evaluate how cybersecurity decisions affect real industrial operations.
