The GICSP certification validates a practitioner’s ability to secure industrial control systems across their entire lifecycle, from design to decommissioning. Developed by GIAC alongside global industrial automation experts, this vendor-neutral credential bridges IT, engineering, and Cyber Security. kodestree’s training walks you through ICS components, network architecture, attack surfaces, and governance using real lab scenarios, giving working professionals a structured, practitioner-focused path toward this respected OT security credential.
Prerequisites
GIAC does not enforce any mandatory eligibility criteria to sit for the GICSP exam, which makes this a genuinely open entry point into OT/ICS security. That said, learners get the most value out of the program when they walk in with:
- A working knowledge of basic networking concepts (TCP/IP, ports, protocols)
- Familiarity with fundamental IT or cybersecurity terminology
- Exposure to industrial, manufacturing, energy, or utility environments (helpful, not mandatory)
- A genuine interest in bridging IT security practices with engineering/OT operations
Why Learn GICSP?
Industrial control systems now sit at the center of national security conversations. Power grids, water treatment plants, pipelines, and manufacturing floors are being connected to corporate networks faster than most security teams can secure them, and regulators have taken notice. Frameworks like NERC CIP, IEC 62443, the EU’s NIS2 directive, and DoD Directive 8140 are pushing organizations to prove their OT workforce is genuinely qualified, not just IT-certified.
This is exactly the gap GICSP was built to close. It’s one of the very few credentials that tests both engineering-side and cybersecurity-side knowledge in the same exam, which is why it carries real weight with employers who need staff capable of speaking both languages. Add in a persistent global shortage of OT-savvy security talent and rising salaries in critical infrastructure roles, and GICSP becomes less of a resume add-on and more of a career accelerator for anyone serious about industrial cybersecurity.
Course Objectives
By the end of this training, you will be able to:
- Explain how ICS/SCADA environments differ from traditional IT networks
- Map assets and zones using the Purdue Reference Architecture
- Identify common attack surfaces, vectors, and threat actors targeting OT systems
- Apply defense-in-depth principles to industrial network design
- Harden Windows and Linux systems used within ICS environments
- Interpret and secure ICS-specific protocols such as Modbus and DNP3
- Build the fundamentals of an ICS security governance program
- Approach GICSP exam domains with a practitioner’s confidence, not just theory
What You Will Learn
This course walks you through the full breadth of skills the GICSP exam and real OT roles demand:
- ICS/SCADA fundamentals, components, and industry-specific terminology
- Purdue Model levels 0 through 3 and secure zoning practices
- Field devices, controllers (PLC/RTU), and Safety Instrumented Systems
- Network architecture, segmentation, and enforcement zone devices
- ICS communication protocols and how they get exploited
- Wireless technologies used on the plant floor and their weaknesses
- Endpoint hardening, patching strategies, and basic cryptography in OT
- Risk-based incident response and disaster recovery for control systems
- Building and documenting an ICS security policy and governance program
Who Is this Course For?

Career Outcomes
GICSP-certified professionals are sought after across energy, manufacturing, oil & gas, water utilities, transportation, and defense sectors. Common roles include:
- ICS/OT Security Engineer
- Industrial Cybersecurity Analyst
- Control Systems Security Specialist
- SCADA Security Consultant
- Critical Infrastructure Risk Analyst
- OT Incident Response Lead
Industry salary surveys place OT/ICS security professionals well above the general cybersecurity average, with senior roles in critical infrastructure often crossing into six figures in the US market, and GICSP is frequently listed as a preferred or required credential in these job postings.
