Most Popular Types of Access Control Systems

Monday May 10, 2021

Access control systems have been a crucial part of a business’s security system for decades now. However, over the years, the system has significantly evolved with the ever-changing needs of business security and safety.

There are various types of access control systems that offer distinct features. Hence, it is vital that you consider all types before picking a system that works best for your business.

Access control systems come in two broad styles: traditional standalone systems and networked IP (Internet Protocol) systems. Let’s take a brief look at it.

Standalone VS IP Access Control Systems

A traditional standalone system is suitable for managing access control in smaller businesses. The entire system operates through an access control panel. The control panel connects the electronic door locks, cameras and different readers with communication wiring and power.

On the other hand, IP networked control systems operate via an Ethernet or wireless connection. This method of access control is becoming more popular with the advancement of technology. It is more fitting for bigger business firms as you can use it on an unlimited number of doors.

Now that’s out of the way, let’s go through the three main types of access control systems.

Mandatory Access Control (MAC)

MAC is the strictest access control system there is. Hence, this system is primarily used in government or military establishments.

Here, the system administrator will set all the access control settings. Additionally, only the custodian or owner has access to the system. But even he or she can’t change the access control settings without the system administrator’s permission.

This makes for a secure access control system for the businesses that need the utmost levels of safety.

Discretionary Access Control (DAC)

When it comes to DAC systems, the business owner or custodian can access and set up the access control settings. DAC systems give business owners complete control over the entry of employees to specific areas. They become the sole decision-maker for all security engagements.

In this system, every entry point will have an Access Control List, including the names of individuals or groups who can access that specific area. Business owners can change the list anytime they want.

Role-Based Access Control (RBAC)

RBAC is also known as non-discretionary access control system. In this system, access is granted to individuals based on their designation/role within the organisation.

The RBAC system ensures that only the designated employees can access rightful information or areas required for their job. Hence, it protects all your sensitive information from unauthorised individuals.


A well-integrated access control system can improve your business’s security by offering you complete control over who gets to enter which area. This way, you can be ensured at all times that only your trusted “authorised” employees are accessing the designated working space.

Before picking the type of access control system, make sure to take a broad look at your business’s security requirements. And accordingly, you can pick the best type of access control system that works out for you and your business!
