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.
