The Cybersecurity Engineering team needs an additional Secure Systems Engineer I. The Cybersecurity Engineering team is a shared services team that supports the development of products throughout the Avionics Strategic Business Unit wherever the customer has security requirements, or the system is exposed to cyber threats by it’s connectivity or operational use. We develop tools and testing techniques to highlight residual defects in product design or implementation. These defects can lead to vulnerabilities that negatively impact the confidentiality, integrity, or availability of a system. Members of the security engineering team pursue security excellence by embedding with the design and implementation teams as subject matter experts supporting our Secure System Development Life Cycle (SSDLC).

Supporting this Cyber Security Engineering team’s mission involves: developing threat models and information flow architectures to ensure data can be properly isolated in motion and while at rest, implementing mandatory access controls (MAC) through the development of Security Enhanced Linux (SELinux) policies, developing and executing fuzzing and penetration tests to evaluate the robustness of the exposed attack surface, reviewing code to identify weaknesses in the implementation of security functions, and conducting vulnerabilities assessments of proposed and in-service systems.
