A system&#x27;s security comes from the security of its components and their interactions. The functionality of each will be expressed in a language. That language will have features that affect the security of that component. Therefore, security is a component of languages and systems.<p>I&#x27;ll go further to say language security is a subset or component of securing a system wherever it could be applied. This has been known since at least MULTIC&#x27;s where the choice of PL&#x2F;0 dodged some security vulnerabilities due to language&#x27;s attributes. It&#x27;s been known for reliability at least since Burroughs used ALGOL variant for their OS.
