Cyber Security for OT / IACS
Interconnection between Functional Safety and Cyber Security
Cyber Security in Operational Technology (OT)/Industrial Automation & Control System (IACS) has a lot of differentiators versus Information Technology (IT) systems, technologies (real time) and dedicated controllers. OT/IACS need different approaches and solutions. For this reason, we have to comply with the dedicated ISA/IEC 62443 series in addition to the ISO 27001 standard.
Cyber Security is a vast subject that involves Humans & Technologies “People at the Heart of Digital”
There are a lot of similarities and interactions between Functional Safety and Cyber Security for Industrial Control Systems (IACS), our clients have been looking for this since the end of 90’s.
In the 2020’s, cyber threats/vulnerabilities shifted into cybercrime, rather than simply denied of services. This requires much more effort in the company’s organisation.
- Cyber-attacks can have an impact on manufacturing plant safety risks (human, assets and the environment) and must be considered in functional safety studies,
- Modification of the mandatory safety requirements of IEC 61511 2nd Edition 2016 – clause 8.2.4 is ensuring that a Security Risk Assessment (or also called Cyber Security Risk Assessment) is carried out to identify security vulnerabilities of Safety Instrumented Systems (SIS),
- Evolution of ISO 27001 standard,
- New ISA/IEC 62443 (Formerly ISA-99) series.
