Mandatory Access Control (MAC) is a robust security model when it comes to hardening, as it enforces strict policies on operating systems and applications regarding system access. In MAC-based hardening, the end-users are not allowed to modify access controls on your system.

How MAC-based Hardening Works

Typical MAC mechanisms work based on predefined security attributes or labels. These labels determine access permissions and are integrated within the system to classify data, resources, and users. Once these labels are in place, the operating system or a trusted security kernel rigorously enforces the constraints on how they access data.

Benefits of MAC-Based Hardening

MAC-based hardening offers numerous benefits for organizations seeking to improve their cybersecurity posture:

There are various MAC models implemented in modern software systems. Some of the most popular models include:

Implementing MAC-Based Hardening

To implement MAC-based hardening, it’s important to follow these general steps:

In summary, MAC-based hardening offers robust access controls by enforcing strict policies in accordance with your organization’s security requirements. In doing so, it reduces the potential for unauthorized access to data and resources, ultimately enhancing your cybersecurity posture.
