Protection mechanism

In computer science, protection mechanisms are built into a computer architecture to support the enforcement of security policies.Jones 1975 A simple definition of a security policy is "to set who may use what information in a computer system".

The access matrix model, first introduced in 1971,Lampson 1971 is a generalized description of operating system protection mechanisms.Landwehr 1981

The separation of protection and security is a special case of the separation of mechanism and policy.Wulf 74 pp. 337–345
