Cybersecurity professionals are strengthening their expertise in industrial cybersecurity through PECB’s ISA/IEC 62443 Lead Implementer training, with participants completing the first two days of the program focused on securing operational technology (OT) and industrial control systems (ICS). Taher Amine ELHOUARI, Cybersecurity Leader and Information Security Strategist, shared updates on the progress of the training, highlighting the value of discussions among senior cybersecurity professionals and OT/ICS security architects participating in the program. The training is designed to provide professionals with deeper knowledge of ISA/IEC 62443 standards and their practical implementation across industrial environments, where cybersecurity requirements must align with operational needs, engineering considerations, and risk management practices.
The initial two days of the training focused on several important areas related to industrial cybersecurity, including system security requirements, security levels and maturity assessments, threat landscapes, physical security, access control, supply chain security, auditing and certification processes, and patch management within Industrial Automation and Control Systems (IACS) environments. According to ELHOUARI, the sessions extended beyond theoretical discussions by incorporating practical perspectives, field experiences, and professional insights from participants working in cybersecurity and industrial security domains. The exchange of knowledge among experienced professionals helped create a deeper understanding of how cybersecurity standards can be applied in real world environments where organizations must manage complex operational requirements while protecting critical systems.
ISA/IEC 62443 has become an important framework for organizations seeking to improve the security of industrial automation and control environments. Unlike traditional information technology environments, OT and ICS ecosystems often involve specialized equipment, long operational lifecycles, and strict availability requirements. Implementing effective security measures in these environments requires organizations to consider architecture design, governance, risk management, operational processes, and the specific challenges associated with industrial systems. The training aims to support professionals in understanding these requirements and developing the skills needed to implement cybersecurity programs aligned with international standards. Topics such as security requirements, maturity evaluation, certification processes, and supply chain protection are increasingly relevant as industries continue to digitize operations and connect industrial systems with broader enterprise networks.
The completion of the first two days marks the halfway point of the ISA/IEC 62443 Lead Implementer journey, with the remaining sessions scheduled for the following weekend. The upcoming days will focus on completing the training program and bringing together the concepts covered throughout the course. The participation of cybersecurity leaders, information security professionals, and OT security specialists reflects the growing importance of specialized knowledge in protecting industrial environments against evolving risks. As organizations across sectors continue adopting connected technologies, industrial cybersecurity training programs such as this provide professionals with structured approaches to managing security challenges, improving cyber resilience, and supporting secure operational environments. The ongoing development of expertise in standards such as ISA/IEC 62443 is expected to remain an important focus for organizations seeking to strengthen protection for critical infrastructure, manufacturing systems, and industrial networks.
