Discretionary access control is commonly discussed in contrast to mandatory access control (MAC). Occasionally, a system ...

8. Lattice-based access control - Wikipedia

   en.wikipedia.org/wiki/Lattice-based_access_control

   For example, if two subjects A and B need access to an object, the security level is defined as the meet of the levels of A and B. In another example, if two objects X and Y are combined, they form another object Z , which is assigned the security level formed by the join of the levels of X and Y .

   An intercom and/or video camera are often used to allow the guard to control the trap from a remote location. In an automatic mantrap, identification may be required for each door, sometimes even different measures for each door. For example, a key may open the first door, but a personal identification number entered on a number pad opens the ...
