Whether you’re managing a small business or a large corporation, having a robust access control system can make a significant difference in protecting your people, assets, and information. Whether you’re protecting sensitive areas, managing employee access, or preventing external breaches, understanding the types of physical access control systems can help you make informed decisions for your organisation. Let’s explore what access control is, its benefits, and the 4 types of access control.
Access control for physical security refers to the systems and protocols used to manage and restrict entry to buildings, rooms, or other physical spaces. These systems are designed to ensure that only authorised personnel can enter designated areas, protecting valuable assets, sensitive information, and the safety of individuals inside.
A physical access control system typically consists of:
By combining these elements, physical access control systems provide a layered defence to safeguard your business.
Prevent unauthorised individuals from entering restricted areas, reducing theft, vandalism, and other security risks.
Protect employees and visitors by ensuring only vetted individuals can access certain spaces.
Generate detailed logs of who enters and exits specific areas, providing an audit trail for investigations or compliance.
Quickly adjust access permissions for employees, contractors, or visitors as needed.
Eliminate the need for traditional keys, which can be costly to replace and easy to duplicate.
Despite the benefits, it’s interesting to find that 60% of organisations still rely on ID badges for access control, despite the emergence of newer technologies.
Physical access control systems can be categorised into four main types, each with distinct features and use cases:
Discretionary Access Control is a flexible model where the owner of a space decides who can access it and under what conditions. For physical security, this often means that a manager or administrator grants permissions to individuals.
Advantages: Easy to implement and modify; suitable for small businesses or offices.
Disadvantages: Vulnerable to human error and insider threats, as permissions are managed manually.
Example: An office manager granting employees access to specific rooms via keycards or codes.
Mandatory Access Control is a highly secure and centralised model where access permissions are strictly controlled by a governing authority. Users cannot modify their access rights.
Advantages: Offers maximum security, making it ideal for highly sensitive facilities like data centres, research labs, or government buildings.
Disadvantages: Complex to implement and less flexible for day-to-day operations.
Example: A classified government building where access is restricted based on security clearance levels and enforced through biometric scanners and security checkpoints.
Role-Based Access Control simplifies management by assigning access permissions based on roles within an organisation. For physical security, this means that individuals in specific roles are only granted access to areas they need in order to perform their duties.
Advantages: Streamlined and scalable, reducing administrative overhead.
Disadvantages: Requires clear definitions of roles and responsibilities.
Example: Only members of the IT department have access to the server room, while only HR personnel can access employee records storage.
Attribute-Based Access Control uses a combination of attributes, such as time, location, or job function, to determine access. This model is highly dynamic and adaptable to complex security needs.
Advantages: Granular control over who can access specific areas under specific conditions.
Disadvantages: Complex to configure and maintain, requiring advanced systems.
Example: Allowing cleaning staff access to certain rooms only after business hours or granting contractors access to a building only on specific days.
Access control models form the framework that guides how permissions are granted and enforced. In the context of physical security, these models dictate how individuals interact with barriers like doors, turnstiles, and gates. The four main models—Discretionary Access Control (DAC), Mandatory Access Control (MAC), Role-Based Access Control (RBAC), and Attribute-Based Access Control (ABAC)—can be applied directly to physical spaces to ensure the appropriate level of security.
For example:
The most widely used model for physical security is Role-Based Access Control (RBAC). Its practicality and efficiency make it the go-to choice for businesses of all sizes. By organising permissions around roles rather than individuals, RBAC reduces administrative complexity and ensures that access is consistently aligned with organisational responsibilities.
For example, a healthcare facility might use RBAC to grant doctors access to operating rooms, nurses access to patient care areas, and administrative staff access to records storage, all without having to manage individual permissions.
