The Top Skills Every OT Security Professional Needs in 2024!

As operational technology (OT) security continues to evolve, the demand for skilled professionals in this niche field is higher than ever. Stack Digital, a leader in OT security recruitment, understands the unique challenges and requirements of this market. To help you stand out in this competitive landscape, we’ve identified the top skills in demand for OT security professionals in 2024.

1. In-Depth Knowledge of Industrial Control Systems (ICS)

Understanding the intricacies of ICS is foundational for any OT security professional. These systems include SCADA (Supervisory Control and Data Acquisition), DCS (Distributed Control Systems), and PLCs (Programmable Logic Controllers). Mastery in these areas is crucial as they form the backbone of industrial operations in sectors like manufacturing, energy, and utilities.

2. Cybersecurity Fundamentals and Advanced Skills

While OT security has unique aspects, a strong grasp of general cybersecurity principles is indispensable. Professionals must be adept in:

• Network security: Protecting communication channels within OT environments.
• Incident response: Quickly identifying, analyzing, and mitigating security breaches.
• Vulnerability assessment and penetration testing: Identifying and addressing security weaknesses within OT systems.

For those transitioning from IT to OT security, strengthening these skills can facilitate a smoother shift.

3. Compliance and Regulatory Knowledge

OT environments are subject to stringent regulations and standards. Familiarity with frameworks like NERC CIP (North American Electric Reliability Corporation Critical Infrastructure Protection), IEC 62443 , and NIST SP 800-82 is essential. Professionals must not only understand these standards but also know how to implement and maintain compliance within their organizations.

4. Risk Management and Threat Intelligence

Risk management in OT involves identifying potential threats, assessing their impact, and implementing measures to mitigate them. This skill set includes:

• Risk assessment methodologies: Quantifying risks to prioritize mitigation efforts.
• Threat intelligence: Staying updated on the latest threats and vulnerabilities specific to OT environments.

Access to up-to-date threat intelligence can significantly enhance an OT security professional’s ability to protect critical infrastructure.

5. Technical Proficiency in OT Security Tools

Proficiency in specialized OT security tools is increasingly important. Tools such as Nozomi Networks , Dragos , and CyberX offer capabilities tailored to OT environments, including real-time monitoring, threat detection, and incident response. Familiarity with these tools not only enhances your technical skill set but also makes you a more attractive candidate to potential employers.

6. Certifications

Certifications validate your expertise and commitment to the field. Here are some key certifications highly regarded in OT security:

• Global Industrial Cyber Security Professional (GICSP): This certification bridges IT and OT, focusing on protecting critical infrastructure.
• Certified Information Systems Security Professional (CISSP): While not specific to OT, CISSP is a highly respected certification covering a broad range of cybersecurity topics.
• Certified Information Security Manager (CISM): This certification is geared towards management and governance of IT security, applicable to OT environments as well.
• Certified SCADA Security Architect (CSSA): Focused specifically on SCADA systems, this certification covers security principles and practices for these critical systems.
• Certified Ethical Hacker (CEH): Understanding ethical hacking techniques is beneficial for identifying and mitigating vulnerabilities in OT systems.
• ISA/IEC 62443 Cybersecurity Certificate Programs: These certifications cover various aspects of industrial cybersecurity standards and practices.

7. Soft Skills and Communication

Technical skills alone aren’t enough; soft skills play a crucial role in OT security. Effective communication, both written and verbal, is essential for collaborating with various stakeholders, including engineers, IT staff, and management. Additionally, problem-solving skills and the ability to work under pressure are highly valued in this field.

8. Continuous Learning and Adaptability

The landscape of OT security is constantly evolving. Staying current with the latest trends, threats, and technologies is vital. Engaging in continuous education through certifications (such as CISSP, GICSP, and CISM) and training programs can keep your skills sharp and relevant.
