Kurzfassung der Arbeit:

„In previous years, the threat landscape for avionic systems, especially with a military background, became more dangerous. Additional, the complexity for aircraft systems is increasing as well as the number of threats, attacks, and vulnerabilities against computer systems. From this it follows, core units such as real-time operating systems need to be secure to provide shelter against possible cyber security threats.
This thesis discusses and tests avionic relevant categories separated into common threats, attacks, and vulnerabilities for the real-time operating system VxWorks 7. The security of the RTOS is evaluated on a simulated target using varying security configurations of the real-time operating sys- tem. Possible security technologies and mechanisms provided by VxWorks are viewed and evaluated, regarding their reaction against threats, attacks, and vulnerabilities.
Issues appeared with basic attacks and vulnerabilities such as buffer overflows or string vulnerabilities, where negative impact on the system is noticeable. Good security practices are observed in security areas such as cryptography and privilege management.
The study reveals security issues as well as good protective technologies and mechanisms for the real-time operating system VxWorks 7 in the area of avionic systems.
Furthermore, additional security technologies and mechanism, which can provide further protection against common attacks, threats, and vulnerabilities, are introduced.“
