The development in the technological landscape has led to a global transformation of several industrial verticals, resulting in the accumulation of digital technologies and industrial systems in an ecosystem. This provides profitable opportunities for IIoT and M2M communication. Therefore, when an Industrial Control System is combined with digital technologies, it consists of multiple devices embedded in a diversified landscape, communicating with the platform and each other.
Today, several industries, including energy, oil, and gas, manufacturing, metals and mining, transportation systems, etc., widely use IIoT-based technologies. The transformation of these industries is ultimately dependent on control systems. However, ICS environments are more vulnerable to cyber-attacks because of the diversified ecosystem and a large number of embedded devices. In 2021, 39.6% of ICS computers were attacked in the world.
Therefore, preventive maintenance is needed to keep the ICS system working properly. While it is necessary for reducing the chances of equipment failure and unexpected machine downtime, it can be challenging to implement it. In this article, we will discuss the challenges in preventive maintenance for ICS. But first, let’s talk about the importance of preventive maintenance.
