Initial situation and project objective
The significance of IT security is permeating increasingly large areas of our lives. These days, more and more industrial systems are connected with each other or cloud services via the Internet. Doing so increases productivity and can even provide access to new fields of business. At the same time, though, this connectivity potentially gives attackers more opportunities to penetrate control networks.
Phoenix Contact is a global manufacturer of industrial controllers. Its controllers need to be connected to the Internet to function along the lines of industry 4.0. This type of Internet access requires particular protection, e.g. to prevent cyberattacks. For this purpose, the IT security standard IEC 62443 defines requirements that specifically address automation technology; these requirements apply to products as well as the associated development processes.
