How can IEC 62443 certification help IACS service providers?

May 28, 2021

In the previous blog, it is discussed that how IEC 62443 can help an asset owner. In this blog, let us have a look at how IEC 62443 is useful for IACS service providers.

IEC 62443-2-4 and/or IEC 62443-3-3 will apply to you if you are a system service provider who provides system integration service or system maintenance service to the asset owner. IEC 62443-3-2 may also apply if a risk assessment is to be done by the service provider.

IEC 62443-2-4 focuses requirements on the integration capabilities of the service provider while IEC 62443-3-3 focuses on the security capabilities of the system itself.

The IACS service provider can be certified per IEC 62443-2-4 resulting in different Maturity Levels, i.e. ML 1 to ML 4.

The system integrated by the IACS service provider can be certified per IEC 62443-3-3 resulting in different Security Levels, i.e. SL 1 to SL 4.
