DAC, RBAC, MAC, and Cloud-Based Access Control: Different Access Control Types and How They Work
Access control systems have become integral to modern business security strategies. Designed to protect facilities, assets, and data, these systems provide enhanced management over who enters different areas within a building and when. For IT Directors, Directors of Operations, or anyone within the organization tasked with implementing and maintaining an access control system, understanding the nuances of access control systems is crucial for making informed decisions about implementation, integration, and long-term management. Here, we’ll explore how access control systems work, focusing on their types and integration capabilities, so you can assess their suitability for your organization.
Types of Access Control Systems
Access control systems can be divided into several types, each with unique characteristics and use cases. Here, we’ll break down the main types most commonly deployed in business environments:
1. Discretionary Access Control (DAC)
In a Discretionary Access Control (DAC) system, the business owner or administrator has the discretion to set policies for who can access specific areas or resources. This type of system allows the control of permissions based on a flexible approach, where users can often modify access rights to their resources. While this flexibility is beneficial, it may present security risks if not properly managed, as unauthorized changes can lead to vulnerabilities.
How Discretionary Access Control (DAC) Works: Users are assigned access rights directly by an administrator. For example, an office manager could have access to an entire office suite, while a contractor might only have access to specific meeting rooms. Access rights can be adjusted easily, allowing for a customizable approach to security management.
Ideal For: Smaller businesses or organizations with straightforward access needs and less stringent compliance requirements.
2. Role-Based Access Control (RBAC)
Role-Based Access Control (RBAC) assigns access rights based on roles within the organization. Instead of setting permissions for each user individually, access rights are defined by job function—streamlining the administration of user access. This system helps ensure that employees only access the information and areas pertinent to their work.
How Role-Based Access Control (RBAC) Works: Access policies are pre-set according to roles such as “Sales Manager” or “IT Staff.” When an employee’s job function changes, their access rights are simply updated by modifying their role. This reduces the administrative burden and ensures consistency in applying access controls.
Ideal For: Medium to large organizations with well-defined job roles and a need for scalable security management.
3. Mandatory Access Control (MAC)
Mandatory Access Control (MAC) systems are characterized by their high-security policies and rigid access protocols. Access permissions are centrally controlled and cannot be altered by individual users. These systems are often used in environments where security is paramount, such as government or military institutions.
How Mandatory Access Control (MAC) Works: Administrators set strict policies where access levels are determined by a combination of user credentials and security clearance levels. This type of system relies on classifying resources and matching users to predefined clearance levels for access.
Ideal For: Highly secure business environments with stringent regulatory requirements.
4. Cloud-Based Access Control
Cloud-based access control systems offer flexibility, scalability, and real-time management capabilities. These systems store data on remote servers, allowing administrators to manage access from anywhere via a secure web interface or mobile application. They are especially advantageous for businesses with multiple locations or for those looking to centralize their security operations.
How Cloud-Based Access Control Works: Access control data, including user credentials and access logs, is managed through a secure cloud platform. Integration with mobile devices allows for real-time updates and alerts, making it easy to modify access permissions instantly.
Ideal For: Multi-location businesses or organizations that need remote management capabilities and real-time oversight.
