Different Types of Access Control Systems

There are two major types of access control systems: discretionary and rule-based. Discretionary access controls are easy to set up and configure and allow the business owner to assign privileges based on an individual’s role and job description. They are also the least restrictive form of system. They use group membership and Access-Control-Lists (ACLs) to determine who can and cannot access certain resources.

A standalone component is an access control device that can only be installed on one specific point. This type does not require any wired installation, so installation time on the site is significantly reduced. This type of system is also easy to retrofit, allowing it to be installed on existing premises. It can also be integrated into a larger access control system. Examples of standalone components include electronic door locks, Mechatronic Cylinders, and Digital Cylinders.


The most restrictive access control system, MAC, is usually used by government entities and the military. The MAC operates on the user’s PC, and it controls who can access any given door. Once in the system, the user cannot change their permissions. In contrast, DAC is more common and is the default option. It allows business owners to decide who can enter and exit a building and work. The Access Control List (ACL) is our entry point.


The most common type of access control system is role-based. Roles are grouped by job description and business responsibilities, ensuring that lower-level employees don’t access top-secret information. A role-based system is easier to implement and manage than a flat-out access control system. For example, marketing employees should not have access to employee salaries. As a result, a role-based system is ideal for large businesses.

An access control system can limit access to certain areas of a building. Depending on the requirements, it can limit access to files, printers, and workstations. Other types of systems restrict entry to specific areas of a building. These systems can be customized to suit the business’s needs. In addition, they can be set to be network-based so that users can access any facility without their physical identity.

Standalone systems are designed for single access points. A standalone component will determine whether an individual has access or not to a particular area based on the permissions granted to that person. They are easier to install than wired systems because they don’t need to be wired. Easily retrofitted components can be integrated into a larger access control system.
