This increased connectivity has made them more software-dependent and therefore more vulnerable to attacks. This vulnerability is due to the heterogeneity of technologies used in factories and the lack of awareness among users of how to best secure these systems.
This three-part blog series explores the risks associated with CNC machines. We performed a security evaluation on four representative vendors and analyzed technological developments that satisfy the Industry 4 .0 paradigm while conducting practical attacks against real-world installations.
For our research, we picked vendors that are:
A machine tool is a device that uses cutting tools to remove material from a workpiece. This process, called machining, results in the desired geometry of the workpiece. Machining is a subtractive process, meaning that the material is removed from the original geometry to create the desired shape.
Numerical control (NC) is a technology that allows machines to be controlled by computers. This technology has revolutionized machine tools, making them more accurate and allowing for greater flexibility in their use. NC machine tools are now widely used in production systems and can be used on other types of machines, such as lasers and bending machines.
