The 4 th Industrial Revolution increases connectivity within the production environment by transforming traditional automation systems to cyber-physical production systems.This conversion impacts intralogistics of a factory: Intelligent and interconnected transport systems, in the form of autonomous mobile robots, are increasingly integrated into the production process.This enhanced connectivity expands the attack surface of production facilities for cyber-attacks.In addition, the interconnection of safety and security poses a risk for people working on machines or around mobile robots in case of an attack.In order to highlight the interaction between safety and security, this study discusses the requirements of a mobile robot from both perspectives.Verification in practice is achieved by performing a penetration test on a test environment of a production network with an integrated mobile robot.The discussion of the detected vulnerabilities outlines the hazards of operating a mobile robot in an interconnected production network, causing a loss of Confidentiality, Integrity and Availability.Finally, these results are providing a basis for trustworthy mobile robotics implementations in production plants.
