SANS Institute offers three critical certifications for Industrial Control Systems (ICS) and Operational Technology (OT) cybersecurity professionals:
- GICSP (Global Industrial Cyber Security Professional) – An introductory course bridging IT and OT security.
- GRID (GIAC Response and Industrial Defense) – Advanced defensive strategies for ICS networks.
- GCIP (GIAC Critical Infrastructure Protection) – Focused on power generation and NERC CIP compliance.
You Should Know:
GICSP – Entry-Level ICS Security
- Key Topics: IT/OT convergence, ICS protocols (Modbus, DNP3), risk assessment.
- Book Reference: Practical Industrial Cybersecurity by Brooks & Craig, Jr. (for self-study).
- Linux Command for ICS Protocol Analysis:
tcpdump -i eth0 -nn -s0 -vv port 502 Capture Modbus traffic
GRID – Advanced ICS Defense
- Key Topics: Incident response, network segmentation, threat hunting in OT environments.
- Practical Defense Commands:
Network segmentation check (Linux) iptables -L -n -v | grep DROP Verify firewall rules
Windows command for ICS service monitoring Get-Service | Where-Object {$_.DisplayName -like "SCADA"} | Select-Object Status, Name
GCIP – Power Sector Security
- Key Topics: NERC CIP compliance, grid security, physical/logical access controls.
- Useful Command for Compliance Audits:
Check unauthorized users in Linux (NERC CIP audit) grep -E 'sudo|wheel' /etc/group Verify admin groups
What Undercode Say:
SANS certifications remain the gold standard for ICS/OT security, despite high costs. For those unable to attend, hands-on labs and open-source tools like Wireshark (ICS protocol analysis) and GRR (incident response) can supplement learning.
Prediction:
As ICS attacks rise, demand for GRID-certified professionals will surge, with more organizations mandating NERC CIP compliance training.
