Software components for on-board architectures in the space domain are\nincreasingly reliant on Commercial Off-The-Shelf (COTS), Open Source (OSS) or\nother third party software products. However, these software components often\nhave not been built with mission critical requirements in mind. Development\nproject teams incorporating these products have limited knowledge of or control\nover the processes applied during the design, implementation, testing and\nmaintenance of selected COTS/OSS software products. These constraints generate\nuncertainty of potential software induced failures. Moreover, the lack of\ninformation regarding security vulnerabilities increases the risks of their\nusage, since their exploitation might lead to undesired behaviour of the\nsoftware and therefore to a system failure. The purpose of this paper is to\npresent a combined approach that takes into account reliability and security\nenhancements for third party software, based on Time-Space Partitioning and\nMultiple Levels of Security.\n
