Typical severity: High. Likelihood of attack: Low. An adversary with the ability to alter tools used in a development environment causes software to be developed with maliciously modified tools. Such tools include requirements management and database tools, software design tools, configuration management tools, compilers, system build tools, and software performance testing and load testing tools. The adversary then carries out malicious acts once the software is deployed including malware infection of other systems to support further compromises.
Have a security concept of operations (CONOPS) for the development environment that includes: Maintaining strict security administration and configuration management of requirements management and database tools, software design tools, configuration management tools, compilers, system build tools, and software performance testing and load testing tools. | Avoid giving elevated privileges to developers.
