From the convenience of smart homes to the efficiency of automated manufacturing, we can’t argue the fact that digital technology has brought immense benefits to our society. However, it is quite difficult to ignore the introduction of new vulnerabilities and threats, especially for critical infrastructure systems that are responsible for managing essential services like power generation, water treatment, and even transportation. Industrial Control Systems (ICS) and Supervisory Control and Data Acquisition (SCADA) act as the very backbone of this infrastructure.

Unfortunately, such systems are seeing a rapid increase in cyber-attacks, posing significant risks. This is increasingly worrisome considering a successful attack on an ICS/SCADA system can lead to devastating consequences, causing disruptions to essential services, safety hazards, and even environmental damage. Hence, certified ICS/SCADA cybersecurity professionals are highly in demand. 

This is where ICS/SCADA cybersecurity certifications can prove fruitful. It can help you demonstrate that you hold the relevant expertise in securing these critical systems and can aid in mitigating growing threats. Our guide aims to take a deeper dive into all you need to know about these certifications, allowing you to make an informed decision about pursuing one and boosting your career. 

What Is The Difference Between ICS and SCADA Systems?

While often used interchangeably, ICS (Industrial Control System) and SCADA (Supervisory Control and Data Acquisition) have distinct roles within the industrial automation hierarchy. Here is a deeper look at them both.

Industrial Control System (ICS)

ICS is considered to be an umbrella term encompassing all the different hardware and software elements that automate and control industrial processes.  You can think of ICS as the main key in charge of different elements of a system, such as sensors, controllers, actuators, etc, to achieve a specific goal which could be a variety of things from maintaining pressure in a chemical plant, or regulating temperature in a powerplant, etc. 

All these different elements work together to gather real-time data from the physical process, make control decisions based on pre-programmed logic, and influence the physical world through actuators (valves, motors, etc.).

Supervisory Control and Data Acquisition (SCADA)

SCADA (Supervisory Control and Data Acquisition) is a specific type of system within the ICS architecture. SCADA aims to monitor and control processes remotely. It collects data from sensors and field devices spread across the industrial facility, transmits this data to a central location for visualization and analysis, and allows operators to remotely control equipment and adjust control parameters using a Human-Machine Interface (HMI). SCADA systems provide a central platform for operators to monitor the health of the industrial process, identify potential issues, and intervene if necessary.

Why Pursue An ICS/SCADA Cybersecurity Certification?

The decision to pursue an ICS/SCADA certification can be a wise investment in your future. Here are some strong reasons to consider adding this valuable credential to your skillset and resume:

Increased Earning Potential

The demand for skilled ICS/SCADA professionals is on the rise. Driven by the growing awareness of cyber threats to critical infrastructure. According to Glassdoor, the average salary of an ICS cybersecurity specialist is around $112,000 per year. Earning an INCS/SCADA cybersecurity certification can position you to command a higher salary within this field.

Better Job Security

As per the ISC2 Cybersecurity Workforce Study, the gap is constantly rising between the number of workers needed in cybersecurity and the supply available. And with an increasing focus on securing ICS/SCADA systems, professionals with specialized knowledge in this area are in demand more than ever. Therefore, having a relevant certification demonstrates your qualification and commitment to this field, which, in turn, improves your job security in a competitive market.
