The field of cyber engineering is relatively new as compared to other engineering disciplines such as software, mechanical, and systems. However, as we consistently hear and read about, cyber has rapidly become all-encompassing for every industry, including the Department of Defense. Specifically for DoD and weapons systems, the application of cyber engineering and cyber solutions must account for the entirety of the system life cycle. This requires a cyber test and evaluation strategy be defined from the start of a program and applied throughout the system life cycle, or system �V�. This presentation will discuss the cyber requirements and directives as levied by the Department of Defense and how this affects program test and evaluation strategies and implementation across DoD programs.
