Security Philosophy
“SpaceX's AppSec mission is to be a "trusted partner to development and business teams"and to ensure "security considerations are addressed without slowing down delivery."They act as the "primary point of contact between Security Engineering and development teams"and are involved in "monitoring and responding to bug bounty submissions."Their risk philosophy includes "Experience with threat modeling and secure architecture design"and a "defense-in-depth"approach. Stated goals and pain points include "Experience with secure code development practices"and a need for "automation/scripting (Python, Bash, PowerShell)."Information regarding explicit public statements of a formal AppSec mission page, public security charter, or published risk appetite for AppSec is not publicly available”
