ICS/SCADA Cybersecurity Practice Tests

This practice exam follows the official EC-Council ICS/SCADA Cybersecurity blueprint. Three domains carry 16 percent of the marks each: ICS/SCADA network defense, hacking methodology, and securing the ICS/SCADA network. TCP/IP networking adds another 14 percent, so those four areas together decide almost two thirds of your score. The rest covers vulnerability management (13 percent), intrusion detection and prevention (13 percent), standards and regulation (6 percent), and bridging the air gap (6 percent).

On exam day you face 75 multiple choice questions in 2 hours, delivered online with remote proctoring. The questions here lean into the OT specifics that separate this exam from a general security cert: Modbus, DNP3, and BACnet protocol behavior, the architectural differences between IT and ICS environments, ICS honeypots like Conpot, and the standards you are expected to recognize, including IEC 62443 and NIST SP 800-82.

The exam voucher costs $699 and the certification stays valid for 3 years under the ECE program, so it pays to arrive prepared. Start with the 30 free questions to benchmark yourself, then work through the full 627-question bank until your accuracy holds steady across all eight domains, especially the defense and protocol areas where most of the marks sit.

The EC-Council ICS/SCADA Cybersecurity certification validates a professional's ability to defend Industrial Control Systems (ICS) and Supervisory Control and Data Acquisition (SCADA) networks against cyber threats. The certification covers the full spectrum of OT/IT security—from foundational TCP/IP networking and ICS-specific protocols to advanced topics such as vulnerability management, intrusion detection, digital forensics, and incident response tailored to critical infrastructure environments. Candidates learn to analyze risk across both IT corporate networks and operational technology (OT) environments, with particular focus on the unique architectural and protocol challenges that distinguish ICS/SCADA systems from traditional enterprise IT.

The certification addresses the growing threat landscape targeting critical infrastructure, including documented malware such as Stuxnet and Triton/TRISIS that can cause physical disruption to industrial processes. It bridges the security gap between IT and OT environments by providing defenders with attacker-perspective methodologies—scanning, footprinting, enumeration, and exploitation techniques—so that practitioners can better anticipate and counter adversary tactics against pipelines, energy grids, water treatment facilities, and manufacturing systems.

This certification is designed for IT and OT professionals who administer, patch, or secure ICS and SCADA systems, including System Administrators and System Engineers working in industrial environments such as oil and gas, energy, utilities, and manufacturing. Security Consultants who conduct security assessments of ICS/SCADA installations are also a primary audience, as are Business Systems Analysts who support interfaces between corporate business systems and SCADA networks.

The credential is appropriate for mid-career professionals with a networking and security background who are transitioning into or expanding responsibilities within operational technology environments. It suits those who need a foundational-to-intermediate understanding of ICS/SCADA-specific threats, standards, and defensive strategies, and who are responsible for establishing or maintaining information security policies for critical infrastructure.

There are no mandatory formal prerequisites published by EC-Council for this exam, but candidates are strongly recommended to have Linux operating system fundamentals including basic command-line usage before attempting the course or exam. A solid grasp of essential networking concepts is expected—specifically the OSI model, TCP/IP protocol architecture, networking devices, and transmission media. Familiarity with network traffic inspection tools such as Wireshark, TShark, or TCPdump is also recommended, as is conceptual knowledge of programming or scripting.

Candidates should additionally possess a working understanding of basic cybersecurity concepts including malware categories, intrusion detection systems, firewalls, and common vulnerabilities. Prior exposure to IT security operations or a general security certification (such as CompTIA Security+) would be beneficial, though not required. Minors seeking to sit the exam must provide written parental consent along with institutional documentation per EC-Council policy.

The ICS-SCADA exam consists of 75 multiple-choice questions and must be completed within a 2-hour (120-minute) time limit. The passing score is 70%. The exam is delivered through EC-Council's ECC Exam Center, which provides proctored testing in a controlled environment. Question types are multiple-choice with a single correct answer, testing both conceptual knowledge and applied understanding of ICS/SCADA security principles.

EC-Council publishes an official Exam Blueprint document (available at cert.eccouncil.org) that outlines the topic domains and their respective weightings, which candidates are advised to use as a primary study guide. There are no publicly disclosed unscored or beta questions built into the exam format at this time.

Professionals holding the EC-Council ICS/SCADA Cybersecurity certification are positioned for roles such as ICS/SCADA Security Analyst, OT Security Engineer, Critical Infrastructure Security Consultant, and Industrial Cybersecurity Specialist. These roles exist across high-demand sectors including energy and utilities, oil and gas, water and wastewater, manufacturing, and transportation—all of which face increasing regulatory pressure and threat actor attention. The ICS/SCADA security skills market remains undersupplied relative to demand, with practitioners who can bridge IT and OT security commanding premium compensation, typically in the range of $90,000–$140,000+ USD annually depending on sector and geography.

The EC-Council ICS-SCADA credential serves as a solid entry point into OT cybersecurity and complements other certifications such as GICSP (Global Industrial Cyber Security Professional by GIAC) or ISA/IEC 62443 Cybersecurity certificates. While GICSP is more widely recognized at the senior level, the EC-Council certification offers a more accessible path for professionals transitioning from general IT security into the industrial domain, and is particularly useful for those already embedded in EC-Council's certification ecosystem (CEH, CPENT, CHFI).
