With DAC, users can issue access to other users without administrator involvement. The best example of usage is on the routers and their access control lists. The main advantage of RBAC is that companies no longer need to authorize or revoke access on an individual basis, bringing users together based on their roles instead. Another example is that of the multi-man rule, where an authorized person may a access protected zone only when another authorized person(say his supervisor) swipes along with the person.

(A cynic might point to the market saturation for RBAC solutions and the resulting need for a 'newer' and 'better' access control solution, but that's another discussion.). When it comes to security, Discretionary Access Control gives the end-user complete control to set security level settings for other users and the permissions given to the end-users are inherited into other programs they use which could potentially lead to malware being executed without the end-user being aware of it. Labels contain two pieces of informationclassification (e.g., top secret) and category (e.g., management). More specifically, rule-based and role-based access controls (RBAC). DAC systems use access control lists (ACLs) to determine who can access that resource. There are three RBAC-A approaches that handle relationships between roles and attributes: In addition, theres a method called next generation access control (NGAC) developed by NIST. A software, website, or tool could be a resource, and an action may involve the ability to access, alter, create, or delete particular information.

In a business setting, an RBAC system uses an employees position within the company to determine which information must be shared with them and the areas in the building that they must be allowed to access. Role-based access control (RBAC) is a security approach that authorizes and restricts system access to users based on their role (s) within an organization. Attributes make ABAC a more granular access control model than RBAC. Also, the first four (Externalized, Centralized, Standardized & Flexible) characteristics you mention for ABAC are equally applicable and the fifth (Dynamic) is partially applicable to RBAC.
