Medium Severity
Developers and implementers can increase the assurance in security functions by employing well-defined security policy models; structured, disciplined, and rigorous hardware and software development techniques; and sound system/security engineering principles. Implementation may include isolation of memory space and libraries. The Ubuntu operating system restricts access to security functions through the use of access control mechanisms and by implementing least privilege capabilities.
