• Title: Security Challenges of Complex Space Applications: An Empirical Study
• Authors: Tomas Paulik,
• Abstract summary: I investigate the security challenges of the development and management of complex space applications. I discuss the four most critical security challenges identified by the interviewed experts: verification of software artifacts, verification of the deployed application, single point of security failure, and data tampering by trusted stakeholders. I propose future research of new DevSecOps strategies, practices, and tools which would enable better methods of software integrity verification in the space and defense industries.

• Abstract: Software applications in the space and defense industries have their unique characteristics: They are complex in structure, mission-critical, and often targets of state-of-the-art cyber attacks sponsored by adversary nation states. These applications have typically a high number of stakeholders in their software component supply chain, data supply chain, and user base. The aforementioned factors make such software applications potentially vulnerable to bad actors, as the widely adopted DevOps tools and practices were not designed for high-complexity and high-risk environments. In this study, I investigate the security challenges of the development and management of complex space applications, which differentiate the process from the commonly used practices. My findings are based on interviews with five domain experts from the industry and are further supported by a comprehensive review of relevant publications. To illustrate the dynamics of the problem, I present and discuss an actual software supply chain structure used by Thales Alenia Space, which is one of the largest suppliers of the European Space Agency. Subsequently, I discuss the four most critical security challenges identified by the interviewed experts: Verification of software artifacts, verification of the deployed application, single point of security failure, and data tampering by trusted stakeholders. Furthermore, I present best practices which could be used to overcome each of the given challenges, and whether the interviewed experts think their organization has access to the right tools to address them. Finally, I propose future research of new DevSecOps strategies, practices, and tools which would enable better methods of software integrity verification in the space and defense industries.

  Confidential computing enables the protection of confidential code and data in a co-tenanted cloud deployment using specialized hardware isolation units called Trusted Execution Environments (TEEs) TEEs offer low-level C/C++-based toolchains that are susceptible to inherent memory safety vulnerabilities and lack language constructs to monitor explicit and implicit information-flow leaks. We address the above with HasTEE+, a domain-specific language (cla) embedded in Haskell that enables programming TEEs in a high-level language with strong type-safety.

  We propose an automated collecting framework REEF to collect REal-world vulnErabilities and Fixes from open-source repositories. We develop a multi-language crawler to collect vulnerabilities and their fixes, and design metrics to filter for high-quality vulnerability-fix pairs. Through extensive experiments, we demonstrate that our approach can collect high-quality vulnerability-fix pairs and generate strong explanations.
