Mandatory Access Control (MAC) is most widely used in organizations that value data classification and confidentiality (that is, military institutions). The MAC does not allow owners to have a say in who has access to a device or facility; instead, the owner and custodian manage the access controls.

FREMONT, CA: The advantages of access control for businesses cannot be overstated. It is essential to have a building-wide system that can secure the staff, patrons, documents, equipment, and other properties without fail. Access control is a method of identifying an individual, authenticating them, and then granting them access to their workstation.

There are three types of access control systems:

Discretionary Access Control

Discretionary Access Control (DAC) is a form of access control system that allows a business owner to choose who is allowed to enter a certain venue, either physically or digitally. With DAC, a person has complete control over all security engagement decisions. The disadvantage of DAC is that it allows the end-user full control over security level settings for other users, and the permissions granted to the end-user are inherited into other programs they use, possibly resulting in malware implementation.

Mandatory Access Control

Mandatory Access Control (MAC) is most widely used in organizations that value data classification and confidentiality (that is, military institutions). The MAC does not allow owners to have a say in who has access to a device or facility; instead, the owner and custodian manage the access controls. All end users are usually classified by MAC and given labels that allow them to gain access through security using existing security guidelines.

Role-Based Access Control

Role-Based Access Control (RBAC) is the most common when it comes to access control systems. In both the business world and the home, RBAC has become very popular. In RBAC systems, the system administrator assigns access based on the subject's position within the household or organization, and most privileges are determined by their job responsibilities. As a result, rather than appointing a person to the role of security manager, access control permissions have already been allocated to the security manager position. RBAC makes it much simpler for system administrators since they only have to delegate access to unique job titles rather than several people.
