A review of cyber threats to saftey crucial, space-based framework

Abstract

A space-based system plays a vital role within national critical infrastructures. They are being incorporated into energy distribution software, advanced air-traffic management applications, rail signalling systems, etc. These infrastructures are susceptible to a broad range of security threats thus unfortunately; the end users of communications, location sensing and timing applications often fail to understand these infrastructures. This paper focus on concerns related with potential cyber-attacks. These are very important because future attacks may overthrow many of the safety assumptions that support the condition of critical space-based services. These safety assumptions are based on standard forms of hazard analysis that ignore cyber-security considerations This is a significant limitation when, for instance, security attacks can simultaneously exploit multiple vulnerabilities in a manner that would never occur without a deliberate enemy seeking to damage space based systems and ground infrastructures. The main motive of this research work is to identify attack scenarios that justify the allocation of additional design resources so that safety barriers can be strengthened to increase our flexibility against security threats.
