Fill your knowledge gaps:
Once you have identified your knowledge gaps, you need to fill them with relevant training and education. You can enroll in online courses or certifications that cover the fundamentals of OT Cybersecurity and ISA’s Cybersecurity Certificate Programs.
Get familiar with the OT/ICS domain and terminology. OT/ICS systems vary widely depending on the industry and application. You need to understand the specific functions, processes, and challenges of the OT/ICS systems you want to secure. You also need to learn the common terms and acronyms used in the OT/ICS domain, such as PLCs, HMIs, SCADA, DCS, RTUs, etc.
You can also read books, blogs, podcasts, webinars, or white papers that provide insights and best practices on various topics related to OT/ICS security. You should also keep yourself updated on the latest trends, threats, and incidents in the field by following reputable sources such as ICS-CERT.
Gain hands on experience:
The best way to learn about OT/ICS security is to practice it. You can start by setting up your own OT/ICS lab at home or at work, using hardware or software simulator (eg: PLCsim or Conpot) You can also use online platforms or courses that offer virtual labs or scenarios for OT/ICS security training (Eg: tryhackme ICS attacks rooms, control things IO platforms to gain hands-on experience)
You should also familiarize yourself with the tools and techniques used for OT/ICS security assessment, monitoring, and response, such as network scanners, protocol analyzers, vulnerability scanners, threat intelligence feeds, etc.
You can look for opportunities to gain practical experience in your current role or organization by volunteering for projects or tasks that involve OT/ICS systems or networks.
Network with other OT/ICS security professionals:
One of the most valuable resources for your career transition is the community of other OT Security Specialists. You can learn from their insights, experiences, and advice, as well as find opportunities for collaboration or mentorship.
You can network with other OT Security Specialists by joining online forums, groups, or events; attending conferences or webinars; or participating in competitions or challenges.
