This contribution reflects the outcomes of a Flight Operation Segment (FOS) security operations concept definition study that has been undertaken to identify on a high level the security needs for theses missions, specify related space and ground segment requirements, propose a robust operational concept and identify the impact of the new security services on the existing FOS infrastructure. The authors first create an attacker model and then subsequently for both the telecommand and telemetry links, they identify on a high level a set of threats and connected vulnerabilities than can be exploited by attackers that to harm the spacecraft, execute unauthorized actions on the communicated information or otherwise disrupt the spacecraft availability. From this analysis, the authors define a list of FOS related security requirements which will ensure that the identified vulnerabilities are closed in the FOS components both on the ground and space segment side. The authors further give several possible security scenario definitions for the protection of the flight segment where each scenario represents a different security configuration and with that a certain level of security or a number of acceptable vulnerabilities. Based on the high level mission requirements and operational considerations applicable to the next generation of earth observation missions, the authors select and justify security baseline from the idenified scenarios. They further conduct a high level impact analysis of the selected configuration with respect to the currently existing FOS facilities and interfaces. This analysis takes into consideration different points of view such as operations, engineering and applications. The authors outline on a high level the necessary modifications in the various parts of the operational infrastructure that are required in order to succesfully implement the identified security concept. This includes not only modification of ground software systems but also the deployment of security policies to handle classified information, access control and personnel behavior.
