Network Access Control: What are the types of access control?

What is access control?

Access control encompasses a wide range of activities, from granting legitimate users the ability to perform actions on systems and data, to preventing unauthorized users from accessing sensitive information. To effectively secure systems and data, it is critical to have strong access control measures in place.





What are the 4 types of access control?

There are four common types of access control: role-based access control (RBAC), discretionary access control (DAC), mandatory access control (MAC), and hybrid access control.

RBAC RBAC is the most common type of access control.

DAC: DAC is similar to RBAC, but instead of roles, it uses individual user accounts to determine access. So, in the HR example from before, only the HR manager account would be able to see employee records.





MAC: MAC uses labels to define what level of security clearance someone has. These labels are then used to determine what they can or cannot see – similar to how roles work in RBAC.

Hybrid Access Control: As the name suggests, this type combines elements from both RBAC and MAC (and sometimes DAC as well).

No matter which approach is used, it is important to carefully consider who should have access to which systems and data.

Network Access Control

Network Access Control (NAC) is a system used to control access to a network or computer, based on the computer's compliance with security policies.

The goals of network access control are to prevent unauthorized systems from connecting to a network.

For this to happen networking needs to understand applications and services that travel over its network to and from the user endpoint. The NAC model identifies the access rights of an endpoint by its identity, attributes, and context. Network access control can be considered a type of admission control and can be described in a formal admission control model.
