To prevent this, you can use a combination of Mandatory Access Control (MAC) and namespace isolation. These two security features can help prevent unauthorized access to sensitive data and system resources. In this article, we&rsquo;ll explore how to implement MAC and namespace isolation on a Linux desktop.</p> <h2 id="mandatory-access-control">Mandatory Access Control</h2> <p>Mandatory Access Control is a security feature that enforces a set of rules defining what actions a user or process can perform on a system. One popular MAC system for Linux is SELinux (Security-Enhanced Linux), which was integrated into the Linux kernel in 2003. SELinux provides a robust security framework that can help prevent attacks such as buffer overflows and privilege escalation. Don&rsquo;t bother with other MAC systems unless you have a specific reason to - SELinux is well-maintained and widely supported.</p>
