![]() Once a company is fully integrated and digitalized, testing becomes a challenge more complex than ever before. Testing has always been a critical phase of the change implementation process even in the era of separate OT and IT systems. Testability : Each new system or a change in a system must be tested in an industry setting prior to deployment so that its security and reliable response in various situations can be verified.The question of cybersecurity is especially important for managing infrastructures that are critical for a functional state (production and distribution of electricity and gas), as well as infrastructures with a risk of environmental and health hazard accidents (chemical plants, nuclear power plants etc.). This data must be secured against direct, external hacking attacks but also against unintentional data leaks, for example, as a result of employee error or lack of competence. Security: The interconnection of systems is a key feature in industrial digitalization, which also, however, represents a security challenge in terms of data protection. ![]() I will discuss this and other key challenges of Industry 4.0 in detail below. One of the main challenges of digitalization is cybersecurity. ![]() This type of easy data accessibility, and mutual dependency and interconnection of systems, however, also has certain risks. It is possible to provide monitoring, planning and maintenance, basically, in real time because the data is immediately available. If configured correctly, the interconnection of that infrastructure brings companies advantages in terms of time and money saved. Over time and thanks to technological advances, these areas grew closer until they finally fused together. ![]() The traditional approach was based on separate operational technology (OT) and company information (IT) systems. Industry 4.0 and IIoT are exciting concepts that require a company's infrastructure to be fully interconnected. The entire concept represents full industry digitalization and is closely related to the Internet of things (IoT) infiltrating all industrial areas, resulting in the creation of an industrial internet of things, or IIoT for short. ![]() The fourth Industrial Revolution (also known as Industry 4.0) is a trending topic today. ![]()
