A security model serves several fundamental purposes. First, it provides a precise set of rules that a computer can follow to implement the security concepts and procedures contained in a security policy. Second, it offers a mathematical mapping of theoretical security goals, strengthening the chosen implementation approach. Third, it helps ensure that security policies are consistently enforced across an entire system. Time of day, current geographic location, device IP address
