On Linux, one of the most popular MAC implementations is SELinux (Security-Enhanced Linux) and AppArmor. I&rsquo;ve found AppArmor to be generally easier to use and more widely supported, so we&rsquo;ll focus on hardening your Linux desktop using AppArmor.</p> https://linuxeries.org/post/2026-05-10-using-mandatory-access-control-to-lock-down-y/ Sun, 10 May 2026 09:54:33 +0200 https://linuxeries.org/post/2026-05-10-using-mandatory-access-control-to-lock-down-y/ <h2 id="introduction-to-apparmor">Introduction to AppArmor</h2> <p>I&rsquo;ve seen many Linux users overlook AppArmor, but it&rsquo;s a powerful tool for locking down your system. AppArmor is a Mandatory Access Control (MAC) system that restricts the actions of applications and services, providing a robust way to prevent malicious or compromised apps from causing harm. In this article, I&rsquo;ll walk you through how to use AppArmor to boost your Linux system&rsquo;s security.</p> <h2 id="installing-apparmor">Installing AppArmor</h2> <p>To get started, you&rsquo;ll need to install the AppArmor package on your Linux system. On Debian-based systems, this is straightforward:</p> https://linuxeries.org/post/2026-05-07-using-mandatory-access-control-to-lock-down-y/ Thu, 07 May 2026 10:24:00 +0200 https://linuxeries.org/post/2026-05-07-using-mandatory-access-control-to-lock-down-y/ <h2 id="introduction-to-apparmor">Introduction to AppArmor</h2> <p>I&rsquo;ve been using AppArmor for years to add an extra layer of security to my Linux systems. It&rsquo;s a Mandatory Access Control (MAC) system that lets you restrict what applications and services can do. By defining a set of rules, you can control file access, network connections, and system calls. This helps prevent malicious activities and gives you more peace of mind.</p> <h2 id="installing-and-enabling-apparmor">Installing and Enabling AppArmor</h2> <p>To get started with AppArmor, you&rsquo;ll need to install the <code>apparmor</code> package.
