Roundwood Industrial Estate, Traditionally, Rule-based access control has been used in MAC systems as an enforcement mechanism for the complex rules of access that MAC systems provide. It is driven by the likes of NIST and OASIS as well as open-source communities (Apache) and IAM vendors (Oracle, IBM, Axiomatics). Mandatory vs Discretionary Access Control: MAC vs DAC Differences Role-based access control systems, sometimes known as non-discretionary access control, are dictated by different user job titles within an organization.
