Access Control Systems: A Quick Rundown

Access Control Systems

Access control systems are systems that rely on a locking system that physically (or digitally) restricts access to a location by using a method to verify the identity of the person trying to enter it. There are many techniques, such as RFID cards, Keypad entry, bio-metrics like fingerprints or Retina scanners and NFC radio transmitters. An access control system you probably already use is your cellphone! Your cellphone carries a bio-metric system that reads your fingerprint before unlocking it.

The greatest benefit of the access control system restricts unwanted access to a specific place or entrance in your organization or specific asset room of your organization. Some of you may be asking yourselves, “Don’t keys already do this?” And the answer is yes, but access control is far more efficient at preventing access. Keys are a hassle, they require you to constantly keep track of who has access to the key and allow that person the ability to enter anytime they want. With Access Control Systems, you can control who enters, what time they can enter, record when they enter and revoke access all with a few keystrokes.


There are three main parts to an access control system. The first is the locking system. This is the device that physically moves a bolt inside the door, usually they have an electric motor and require power to operate. This second part determines the identity of the subject; these include keypads, RFID readers or biometric scanners.  The third part is the software and this is where as the operator of the system you want to pay attention. When purchasing a system its extremely important to pay close attention of how this operates because this is usually where the system fails.

Types of Access Control System

There are three methods to determining how the system operates. They basically boil down to how the system grants access. The three methods are called Discretionary Access Control (DAC), Mandatory Access Control (MAC), and Role Based Access Control (RBC).

1. Discretionary Access Control (DAC)

It makes the business persons accountable for taking a decision regarding who is permitted. In specific location either physically or digitally. This is a less strict system as compare to other systems it allows the specific individual to control over the specific things or areas and all the things associated with them.

2. Mandatory Access Control (MAC)

MAC control system offers the highest level of security. They are used in firms that need to focus on secrecy and ordering of data like military secret operations. MAC never allows the different persons to have access in the unit .

3. Role-Based Access Control (RBAC)

RBAC has quickly become the most pervasive system in use today. This system access is managed by the administrator of the system who managed it on the basis of the specific roles of different individuals within the firm. RBAC is flexible, allowing an administrator to give and revoke access to a person.

Benefits to Physical Security

In today’s digital world, the only real way of assuring complete privacy is using physical security. With the internet being so pervasive and complex, there are just too many vectors for hackers to take control of your data online. That’s where physical security comes in. Fraudsters, thieves and hackers can’t access your physical location without standing at your door and being there.  No matter how “secure” your digital security is, it can’t beat a physical lock on a door with some security camera.
