Distributed Access Control System (DACS) [1] is a light-weight single sign-on and attribute-based access control system for web servers and server-based software. DACS is primarily used with Apache web servers to provide enhanced access control for web pages, CGI programs and servlets , and other web-based assets, and to federate Apache servers.

The definition of a closed loop control system according to the British Standards Institution is "a control system possessing monitoring feedback, the deviation signal formed as a result of this feedback being used to control the action of a final control element in such a way as to tend to reduce the deviation to zero."
Privileged Access Management (PAM) is a type of identity management and branch of cybersecurity that focuses on the control, monitoring, and protection of privileged accounts within an organization. Accounts with privileged status grant users enhanced permissions, making them prime targets for attackers due to their extensive access to vital ...
