An access control list (ACL) is a list of access control entries (ACE). DAC mechanisms will be controlled by user identification such as username and password. This paper argues that reliance on DAC as the principal method of access control is unfounded and inappropriate for many commercial and civilian government organizations.

Dynamic Access Control Overview

Mandatory Access Control uses a hierarchical approach: Each object in a file system is assigned a security level, based on the sensitivity of the data. NDAC often refers to mandatory access control (MAC), in which permission is granted only if the subject’s clearance matches the sensitivity level of a given object.A discretionary access control system is a system in which a user with access to a certain level of data can give access to the same level of data to someone else based on their judgement and choice. Typically, the object’s owner is the person who created it. They are called discretionary as users can be given the ability of passing on their privileges to other users, where granting and revocation of privileges is regulated by an administrative policy.
