Computer numerical controls (CNCs) are machines used to produce products in a factory setting. They have been in use for many years, and in the last decade, their use has become more widespread due to increased connectivity. 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. Trend Micro researchers 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.
