Security-focused operating system

This is a list of operating systems with a sharp security focus. Here, ""security-focused"" means that the project is devoted to increasing the security as a major goal. As such, something can be secure without being ""security-focused."" For example, almost all of the operating systems mentioned here are faced with security bug fixes in their lifetime; however, they all strive to consistently approach all generic security flaws inherent in their design with new ideas in an attempt to create a secure computing environment. Security-focused does not mean security-evaluated operating system, which refers to operating systems that have achieved certification from an external security-auditing organization. An operating system that provides sufficient support for multilevel security and evidence of correctness to meet a particular set of government requirements is called a ""trusted operating system"".The list is alphabetical and does not imply a ranking.
