A network security policy (NSP) is a generic document that outlines rules for computer network access, determines how policies are enforced and lays out some of the basic architecture of the company security/ network security environment. [1] The document itself is usually several pages long and written by a committee.
An acceptable use policy (AUP) (also acceptable usage policy or fair use policy (FUP)) is a set of rules applied by the owner, creator, possessor or administrator of a computer network, website, or service that restricts the ways in which the network, website or system may be used and sets guidelines as to how it should be used.

NAC is mainly used for endpoint health checks, but it is often tied to Role-based Access. Access to the network will be given according to the profile of the person and the results of a posture/health check.
A technical implementation defines whether a computer system is secure or insecure.
