Knowing the right one to install

The benefits of access control to companies cannot be overemphasized. Having a building-wide system that can protect your employees, patrons, information, equipment and other assets without question is a must have. Access control is used to identify an individual, authenticate them, and then permit the individual entrance to his or her workstation.


Access control systems come in three variations: 

Discretionary Access Control (DAC), Mandatory Access Control (MAC), and Role-Based Access Control (RBAC).


1. Discretionary Access Control (DAC)

Discretionary Access Control is a type of access control system that allows the business owner to decide which people are allowed into a specific location, physically or digitally. With DAC, an individual is given total control in deciding all security engagement.

The drawback to Discretionary Access Control is the fact that it gives the end-user complete control to set security level settings for other users and the permissions given to the end-user are inherited into other programs they use which could potentially lead to malware being executed.


2. Mandatory Access Control (MAC)

Mandatory Access Control is more commonly utilized in organizations that require an elevated emphasis on the confidentiality and classification of data (i.e. military institutions). MAC doesn’t permit owners to have a say in the entities having access in a unit or facility, instead, only the owner and custodian have the management of the access controls. MAC will typically classify all end users and provide them with labels that permit them to gain access through security with established security guidelines.


3. Role-Based Access Control (RBAC)

Role Based Access Control (RBAC) is the most demanded in regard to access control systems. RBAC has become highly sought-after in the business world and households.

In RBAC systems, access is assigned by the system administrator and is stringently based on the subject’s role within the household or organization and most privileges are based on the limitations defined by their job responsibilities. So, rather than assigning an individual as a security manager, the security manager position already has access control permissions assigned to it.

RBAC makes life much easier because rather than assigning multiple individuals particular access, the system administrator only has to assign access to specific job titles.

How Access Control Works

Access control readers give access to the building based on established credentials. Things like a key card, key fob, or bio-metrics like fingerprints are all considered established credentials.

  1. Door readers are connected to a network. Every person who needs access has a code tied to their credential and the system recognizes that they are authorized to be in the building.
  2. Software tracks who enters and exits the building and has the ability to alert security supervisors, business owners, etc. when someone enters the building after hours or there is a break-in.

When it comes to protecting your home or business, as well as the building’s occupants, access control is one of the best ways for you to achieve peace of mind. But, access control is much more than just allowing people to access your building, access control also helps you effectively protect your data from various types of intruders and it is up to your organization’s access control policy to address which method works best for your needs. Places of business with small or basic applications will probably find Discretionary Access Control to be less complicated and better utilized. If, however, you have highly confidential or sensitive information on your business platform, a Mandatory Access or Role-Based Access Control system are two options you may want to consider
