Cybersecurity Engineer
Protect IT and OT networks, critical infrastructure, and data from cyber threats.
What Cybersecurity Engineers Do
Cybersecurity engineers protect organizations from cyber threats by designing security architectures, implementing controls, and responding to incidents. In engineering and industrial settings, this means securing both IT (information technology) and OT (operational technology) environments — a challenge because OT systems like PLCs and SCADA were often designed without security in mind.
In practice, cybersecurity engineers perform risk assessments, design network segmentation (DMZ architectures, Purdue Model), implement firewalls and intrusion detection systems, manage vulnerability assessments, and develop incident response plans. For critical infrastructure, they must understand regulatory frameworks like NERC CIP (energy sector), CISA guidelines, and IEC 62443 for industrial control systems.
The field is evolving rapidly with zero-trust architecture, cloud security (AWS, Azure security posture management), and AI-powered threat detection. Demand for cybersecurity engineers with OT/ICS knowledge is extremely high, as most security professionals come from an IT background and lack the process knowledge needed to secure industrial systems effectively.
Education & Licensure
No universal PE license; CISSP is the de facto professional standard
BS (4 yr) → CompTIA Security+ → 3 years experience → CISSP or CISM
Key Certifications
| Certification | Issuing Body | Notes |
|---|---|---|
