What Are the Different Types of Access Control Systems?

There are four main types of access control systems. They are MAC, RBAC, and server-based access control. These types of systems allow you to determine who has access to what areas of your building. These systems are often referred to as access control readers, and they give access based on a user’s established credentials. Those credentials include fingerprints, key cards, and fobs. The door readers are connected to the network, and every person who needs access has a code tied to that credential. The access-control software keeps track of who enters and exits the building and can alert security supervisors or business owners to any unusual activity.

Discretionary access control

MAC and DISC work in a similar manner in computer systems. DISC enables the administrators of an organization to define a central policy, whereas MAC allows users to make their own decisions about what access they should be allowed to have. Users can only access certain files or data if they have the corresponding security label assigned to them. DISC systems are generally more appropriate for large sites, as they allow administrators to keep track of who is in and out of the site.

DISC systems are easy to implement and use. They allow administrators to customize permissions for specific users, making them convenient to use. This type of system can be used to manage network resources and is ideal for small businesses and individuals. However, it is important to remember that DISC systems are not perfect and must be used with caution. DISC systems may leave your system susceptible to malware attacks and Trojan horses, so make sure to set the proper security policies before implementing one.


MAC Access Control Systems are a popular choice in many types of commercial facilities. They give administrators granular control over who has access to certain objects and settings. They are resistant to Trojan Horse attacks but require constant system management and planning. In addition, they require extensive initial set-up. This type of access control is also difficult to install and requires continual update and maintenance. Nonetheless, it is an ideal choice for commercial facilities that need to control access.

Some ACS products allow the creation of an access control list, which is a set of rules that define the security policy. The access control list contains access control entries, which are the actual definitions of the rules. The rules can restrict access for a specific user, time of day, IP address, or system. These systems can help protect a variety of sensitive records and ensure that only authorized people can access them. While some ACS systems provide this level of security, others are more restricted.


Role-based access control, or RBAC, is a way to assign permissions to users based on their roles, rather than identities. Using RBAC, organizations can better secure sensitive data and applications by allocating permissions to individual users based on their roles and positions within the company. The key differences between RBAC and other access control systems are the roles and permissions, and how they are defined and enforced.

RBAC is often used by large organizations to give employees access to different resources based on their roles. This makes it easier to manage than lists of access controls. Each role is assigned a set of permissions, and users can be assigned multiple roles within the same organization. This makes it easier to distinguish which roles are relevant to a particular group. RBAC is also easier to administer than access control lists. The key to its success lies in the way it categorizes users.

Server-based access control

With server-based access control systems, you can manage multiple areas and access points without the need for an expensive onsite controller. You don’t have to worry about installing expensive hardware, and it doesn’t require internet access. The software runs on a modem or server, which is connected to your system. A web-based access control system is easy to install and maintain, and can manage your entire security system with ease.

The major benefits of a server-based system are their flexibility. Many applications come with an audit trail, which allows you to keep track of who visits each location, when, and how often. This audit trail will help you set policies, identify vulnerabilities, and monitor employee behavior. Moreover, you’ll be able to monitor access to sensitive information and prevent unauthorized access. Whether it’s an employee who is trying to get into a restricted area or a client, a server-based access control system can help you secure your business.

Attribute-based access control

Attribute-based access control (ABAC) is a type of system that grants access primarily if a person’s attributes match certain criteria. This model differs from traditional discretionary access control in that it replaces the subject with a list of services or attributes. Attribute-based access control systems are appropriate for environments that require identity-less authentication or certificate substantiation.

ABAC systems are flexible and adaptable to a variety of business needs. They are especially useful for large businesses with complex hierarchies. This approach can also accommodate a growing number of users without the hassle of modifying access rules for each new employee. However, it is crucial to keep in mind that if you implement ABAC incorrectly, it can be very difficult to recover from the situation. The benefits of ABAC outweigh the drawbacks.
