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.

[1] Network security involves the authorization of access to data in a network, which is controlled by the network ...
Therefore, a zero trust enterprise is the network infrastructure (physical and virtual) and operational policies that are in place for an enterprise as a product of a zero trust architecture plan. There are several ways to implement all the tenets of ZT; a full ZTA solution will include elements of all three:
Attribute-based access control (ABAC), also known as policy-based access control for IAM, defines an access control paradigm whereby a subject's authorization to perform a set of operations is determined by evaluating attributes associated with the subject, object, requested operations, and, in some cases, environment attributes.
For example, a Group Policy can be used to enforce a password complexity policy that prevents users from choosing an overly simple password. Other examples include: allowing or preventing unidentified users from remote computers to connect to a network share, or to block/restrict access to certain folders. A set of such configurations is called ...
