In this paper we show that it is possible to retrofit a security layer on top of PROFINET IO without changing the underlying transmission system or standards. By introducing security modules, end-to-end network security can be achieved and ensure authentication, integrity and confidentiality for real-time communication. The concept of security modules is a flexible framework and countermeasures can be changed, as security threats and exploits are changing over time. A proof-of-concept implementation shows that it is possible to implement security modules on existing products and secure them against, for example, man-in-the-middle attacks.
