Lab Description

This lab provides a comprehensive guide to enhancing Ubuntu system security through a series of practical labs. You will start by applying best practices for filesystem management, including identifying and disabling unused filesystems to minimize attack surfaces. Following this, you will manage package versions using pinning to control updates, ensuring system stability and security. Further, the lab covers the installation and configuration of AIDE for filesystem integrity monitoring, and demonstrates how to secure the GRUB boot loader with appropriate file permissions and encryption. You'll also verify and configure critical security settings such as NX/XD support, ASLR, and core dump restrictions. Finally, you'll ensure that AppArmor is installed, configured correctly, and check its status to protect your system from potential threats.
