3 Main Types of Access Control Systems

Access control

1. Mandatory Access Control (MAC)

Who Should Use It:

  • Government and military organizations
  • Highly regulated industries such as healthcare and finance
  • Environments with extremely sensitive data

How Does It Work: 

Mandatory Access Control (MAC) is a security model that enforces strict access policies based on the classification of both users and data. It is highly restrictive, with access control solely managed by administrators. 

In MAC, access decisions are made by a central authority, typically an operating system or security administrator, rather than individual users or owners of the resources. 

Users cannot alter permissions, ensuring robust security for sensitive data. It limits resource owners’ access-granting capabilities and assigns unique access levels to users based on “tags,” making it a preferred choice for government entities due to its confidentiality commitment.

Pros:

  • Provides robust security by limiting user discretion
  • Well-suited for environments where data confidentiality is paramount
  • Enables strict control over data sharing and access

Cons:

  • Complex to implement and manage

2. Discretionary Access Control (DAC)

Who Should Use It:

  • Small to medium-sized businesses
  • Collaborative environments where users need flexibility in granting access
  • Environments with less stringent security requirements

How Does It Work: 

Discretionary Access Control (DAC) is a more flexible access control model where users have control over the access permissions of their resources. 

In DAC, resource owners can grant or revoke access permissions to other users or groups. 

The system grants more control to leadership. 

It is based on the principle of “discretion” and decides resource access, regardless of the system administrator’s hierarchy. 

While Mandatory Access Control (MAC) is rigid and low-effort, DAC offers flexibility but requires higher effort for management.

Pros:

  • User-friendly and straightforward to implement
  • Offers flexibility for resource owners to manage access
  • Suitable for environments where trust among users is high

Cons:

  • Vulnerable to misuse or accidental data exposure

3. Role-Based Access Control (RBAC)

Who Should Use It:

  • Large organizations with many users and varied access needs
  • Enterprises with dynamic user populations
  • Environments where roles can be clearly defined

How Does It Work:

Role-Based Access Control (RBAC) is an access control system that organizes users into roles and assigns permissions to these roles [1]. 

Users are then granted access based on their roles rather than their individual identities. Access is determined by the user’s role, preventing lower-level employees from accessing sensitive 

information.

RBAC offers a flexible model that enhances visibility while safeguarding against breaches and data leaks, making it a preferred choice for many executives.

Pros:

  • Scalable and efficient in managing access for large user bases
  • Reduces administrative burden by centralizing access control
  • Facilitates compliance efforts by aligning with organizational roles

Cons:

  • It may become complex to manage as organizations grow

More Detailed & Intuitive Access Control Systems

Badge Access Control

Rule-Based Access Control

Rule-Based Access Control (RBAC) determines access permissions based on predefined rules or conditions. It allows for fine-grained access control by evaluating specific criteria, such as time of day or location, before granting access.

Attribute-Based Access Control

Attribute-Based Access Control (ABAC) relies on user and resource attributes to make access decisions. It

This methodology effectively manages access rights by assessing rules, policies, and relationships while considering user attributes, system parameters, and environmental conditions.

Identity-Based Access Control

Identity-Based Access Control (IBAC) grants or denies access based solely on the user’s identity. Users are authenticated using unique identifiers, such as usernames or employee IDs.

History-Based Access Control

History-Based Access Control (HBAC) considers users’ past behavior and access patterns when making access decisions. It can help identify unusual or suspicious access requests.

What Is an Access Control System? 

An access control system is a security solution that manages and governs entry to physical spaces or digital assets. 

Its key components include authentication, which verifies user identities through passwords or biometrics, and authorization, which determines user access based on roles or attributes. 

These systems ensure that only authorized individuals or entities can access specific resources, bolstering security and asset protection.
