In the world of Linux distributions, maintaining robust security measures is paramount to ensuring the safety and integrity of system operations. Two of the most notable Mandatory Access Control (MAC) security systems utilized by Linux distributions are AppArmor and SELinux. Although they both aim to restrict programs' capabilities and limit their access to system resources, their approaches and implementation diverge significantly. This blog post delves into the differences between AppArmor, commonly used in Ubuntu and other Debian-based distributions, and SELinux, predominantly found in Red Hat Enterprise Linux (RHEL) and other Fedora-based systems.

When managing security on Linux servers, understanding the intricacies of Security-Enhanced Linux (SELinux) across different distributions is crucial. In today’s spotlight, we delve deep into how SELinux is implemented and managed in three popular Linux distributions: AlmaLinux, Rocky Linux, and Ubuntu. What is SELinux? Before we dive into the differences, let’s quickly recap what SELinux is. SELinux is a security architecture integrated into the Linux kernel using the Linux Security Modules (LSM) framework. Initially developed by the United States National Security Agency (NSA), SELinux adds mandatory access control (MAC) to further bolster the system's defense against unauthorized access.

Security-Enhanced Linux (SELinux) is a mandatory access control (MAC) security mechanism implemented in the Linux kernel. It is designed to enhance the security of Linux systems by allowing administrators to have more control over who can access the system. SELinux can be a bit complex, but with proper understanding and configuration, it can significantly enhance the system's security. In this article, we’ll explore what SELinux is, why it's important, and how to configure it on your Linux system. SELinux was originally developed by the United States National Security Agency (NSA) to implement MAC on Linux.
