information flow policy
A triple consisting of a set of security levels (or their equivalent security labels), a binary operator that maps each pair of security levels into a security level, and a binary relation on the set that selects a set of pairs of levels such that information is permitted to flow from an object of the first level to an object of the second level. (See: flow control, lattice model.)
