Flexible and distributed management systems based on mobile agents have certain advantages over centralized and static management architectures. However, security plays a decisive role in terms of acceptance and applicability of mobile agents. In this paper, we analyze the threats and attacks against mobile agent systems used for management purposes. Therefore, general models of mobile agent based management systems are developed. Based on a risk analysis of these models we derive security requirements. In order to satisfy these requirements components and services are identified and integrated in comprehensive security architecture.
