Abstract

Avionics has seen a greatest shift in technology over the last two decades. The severity of the consequences resulting from a lack of risk management in avionics can be seen from recent incidents of unmanned aerial vehicles being hacked or in the hacking of vendor-controlled systems installed in commercial aircrafts. Over a million incidents related to security breaches at cyber layer have been recorded over the last decade, among which 350,000 cyber-attacks alone have taken place in the year 2018. Unfortunately, only a limited set of studies has been conducted on security risk management, particularly specific to avionics. In this article, we aim to identify, analyze and mitigate the security risks of   6 Degree of Freedom Flight Simulator. As a result, we identify 8 risks of level 3-4 as per the IEC 61508 standard. Further analysis of the identified risks yields in another 34 risks. We then mitigate the severity of the identified risks from level 4 to level 2 as per the IEC 61508 standard. The cryptosystem used for risk mitigation performed relatively faster as compared to some of the most recently proposed encryption schemes.
