To implement new software functions and more flexible updates in the future as well as to provide cloud-based functionality, the service-oriented architecture (SOA) paradigm is increasingly being integrated into automotive electrical and electronic architecture (E/E architectures). In addition to the automotive industry, the medical industry is also researching SOA-based solutions to increase the interoperability of devices (vendor-independent). The resulting service-oriented communication is no longer fully specified during design time, which affects information security measures. In this paper, we compare different SOA protocols for the automotive and medical fields. Furthermore, we explain the underlying communication patterns and derive features for the development of an SOA-based Intrusion Detection System (IDS)
