Proximus Luxembourg S.A. was, and is still, actively participating in the efforts of ESA to improve and ensure the overall security of their missions and infrastructures. In this context, they have successfully completed projects like GASF (Generic Application Security Framework), GASF Evolution and PenBox and are currently working on projects like AACT (Advanced Automated Cybersecurity Testing) and SSE4Space (Secure Systems Engineering for Space). 

The GASF study and its continuation GASF Evolution focused on the augmentation of ECSS (European Cooperation on Space Standardization) standards, which are also widely used within the European space sector, to include information security aspects in ESA software development projects. Additionally, a tool (the GASF tool) was developed to guide project teams through the process of defining and iterating security requirements, translate them into suitable security controls and trace decision making process and its consideration within the development. The GASF framework, as well as the tool, have been successfully used in the context of ESA’s Mission data systems Information Security Management System (ISMS) to reduce risks related to software security and is being mandated for usage by the Secure Operations Procedures (SECOPS). PenBox and its continuation AACT, aim to automate the complex, time and resource consuming task of penetration testing without the need for expert penetration testers. They define an automated and repeatable security penetration testing concept for space mission ground segment systems by identifying suitable tools, tactics, techniques and procedures suited to security testing of mission ground segment systems, protocols and interfaces.
