Mandatory Access Control (MAC) For best practices, MAC policy decisions are based on network configuration. In contrast, certain operating systems (OS) enable limited Discretionary Access Control (DAC). MAC advantages and disadvantages depend on organizational requirements, as follows: MAC provides tight...
On the other hand, systems can be said to adopt both mandatory and discretionary access controls at the same time, where DAC refers to one category of access controls that subjects can transfer among each other whereas MAC refers to a second category of access controls imposing constraints upon ...

The earliest work directed toward standardizing an approach providing mandatory and discretionary access controls (MAC and DAC) within a UNIX (more precisely, POSIX) computing environment can be attributed to the National Security Agency's Trusted UNIX (TRUSIX) Working Group, which met from 1987 to...
What is the difference between mandatory access control and discretionary access control? As the highest level of access control, MAC can be contrasted with lower-level discretionary access control (DAC), which lets individual resource owners make their own policies and assign security controls. ...
Health Information Systems (HIS) require an OS which can enforce MAC rules so that access to the resources does not rely on the discretion of the users, thus minimizing the damage when users' applications are compromised. SELinux provides a flexible and fine-grained MAC architecture implementing ...
