Access Control System Types and Its Importance in Visitor Access Control System


  • Mandatory Access Control (MAC)
  • Discretionary Access Control (DAC)
  • Role-Based Access Control (RBAC)

Access control, in terms of information security and physical security, puts selective restrictions on entering a resource or an area. Physical security is the practice of restricting entrance to a premise, establishment, or property. Only authorised people are permitted to enter or exit the premises. Traditionally, a guard is hired to secure the building manually. To allow entry, they also use a lock and a key. However, this traditional solution may pose security risks. It cannot be easy to track and document such practices. Using pen and paper to sign in guests is also unreliable. Moreover, traditional access control can be hard to manage in big establishments. Upscaling can also be challenging with these traditional practices.

In today’s digital age, businesses invest in sophisticated and automated VMS. It also enhances building security. Aside from increasing security, it also increases efficiency in visitor management. Deploying a visitor management system (VMS) software solution with access control integration is a popular choice nowadays. Examples of these access points can be a door access system and turnstiles. Electronic access control automates traditional processes.

Lock and key are the access credentials for traditional systems. In using a VMS software with access control, the credential can be an identity card, barcodes or QR codes, or biometrics. This replaces the mechanical locks and keys of old access systems. Furthermore, these authentication options determine a person’s identity. The ease of use of electronic access systems attracts modern businesses. It also brings a sophisticated ambience to the place of work.

Types of Access Control System Models

There are various types of access control system models. It is useful to consider each model carefully before deploying one. An organisation must identify the fitting type for their businesses to adopt. Factors may include the type and sensitivity of data they need to process. This section describes the most common type of access control model available.

Mandatory Access Control (MAC)

MAC utilizes a non-discretionary model. People’s access is based on information clearance. It is commonly used in companies requiring a strict emphasis on the classification and confidentiality of data. MAC usually classify all end-users and gives them labels or credentials that will permit them to access the premise, following strict security guidelines. The owner of the facility or the custodian has management over the access controls.

Discretionary Access Control (DAC)

DAC puts the responsibility on the business owners on deciding which people are allowed to enter. This type of system is the least restrictive compared to the two types described here. It provides the end-user complete control to set security level settings for other persons.

Role-Based Access Control (RBAC)

In this system, the system administrator manages permissions per role. The access is based on the end user’s role within the organisation. Most privileges and limitations are based on their job responsibilities. Moreover, instead of assigning an individual as a security supervisor, the security supervisor role already has permissions assigned to it. This is in high demand among households and businesses due to its ease of use. Instead of assigning particular permissions to multiple persons, the system administrator will only have to group them or assign specific access based on their job titles.

With electronic access control systems, it is easy to keep track of visitors or employees who entered and left the premise. It also secures sensitive guest information and data. This can also reduce theft and accidents as it gives authorisation to approved personnel only. Integration of access control to an establishment’s VMS enhances on-premise security. Visitor management system enhancements for increased efficiency and security is a popular solution for businesses today towards digitalisation.
