How Users Access and Logon to Systems Access control tools are concerned with determining the allowed activities of legitimate users, mediating between every attempt by a user to access a particular resource in the system. Its main objective is to make sure that undesired users do not get access to certain information; only those who are allowed can access. Role-based access control and Discretionary Access Control both are based on defining the roles and adding each user to the system. Authorization and privileges are granted.

The main difference between these two user control assets is that RBAC has ease of management while DAC is complicated since each new user has to go through all the details the user needs access to and add them to the list.Authentication provides a way of identifying a user by having them enter a valid username and password before access is granted. If the identifications do not match, authentication fails hence permission is denied to access the information. Its purpose is to prevent unauthorized users to access information that they are not entitled to access.
