This is a list of operating systems specifically focused on security. Operating systems for general-purpose usage may be secure without having a specific focus on security.
Similar concepts include security-evaluated operating systems that have achieved certification from an auditing organization, and trusted operating systems that provide sufficient support for multilevel security and evidence of correctness to meet a particular set of requirements.
Security-Enhanced Linux (SELinux) is a module that may be incorporated into a Linux distribution. SELinux gives administrators more control over access of the system. SELinux has been integrated with the Linux kernel by default since 2003.
These operating systems are all engineered around the object-capabilities security paradigm. Instead of the system deciding if an access request should be granted, the bundling authority and designation decides.
