After NMi published its Weighing in Motion standard back in 2016, there have been interesting developments in the field of weighing in motion. One is that WIM-systems did not become simpler, on the contrary, they became more advanced and got equipped with more and more features.
In case of WIM these additional features are, often, intended to offer more and more advanced applications to end-users and to make the systems and the measurements more accurate and more reliable. In addition when developing systems, we want to make sure they are always available to the user, no matter what. End-users will want these WIM-systems to operate 24/7, while the data is guaranteed to be correct and the privacy is not compromised. In other words, how to achieve optimal availability, data quality, integrity and confidentiality over the entire data-chain?
All this can be covered when taking cyber security into consideration when developing, or purchasing systems or components in order to compose your state-of-the-art weighing in motion system. More specifically, the IEC-62443 provides great insight on how to analyze and address the aforementioned areas (technology, people, policy and procedures).
