learn Linux security: logging, auditing, encrypting data, securing services, and using containers
What you'll learn
- Securely manage Linux logs with syslog, rsyslog, and journald for effective system monitoring
- Audit user passwords and file system access with advanced tools like John the Ripper and Auditd
- Encrypt disks and files with LUKS and GPG to protect sensitive data and ensure secure data transmission
- Harden services with SELinux, chroot jails, and LXC containers for enhanced system isolation and security
Requirements
- Learners will need access to a Linux system (physical, virtual, or cloud-based) to practice hands-on exercises. All tools—like syslog, rsyslog, journald, Auditd, John the Ripper, LUKS, GPG, fail2ban, SELinux, chroot, and LXC—are included in most Linux distributions.
Description
This course equips you with essential knowledge and hands-on techniques to secure Linux systems, covering critical aspects of system logging, auditing, data security, and service hardening.
Starting withSystem Logging and Auditing Essentials, you'll learn how to set up secure Linux logging usingsyslogandrsyslog, manage system logs withjournald, and ensure accountability through robust password management and auditing usingJohn the Ripper. You’ll also exploreAuditdfor tracking file system access and analyzeSUIDandSGIDpermissions to identify potential vulnerabilities. Finally, you’ll learn how to secure your SSH service usingfail2banto protect against brute-force attacks.
Moving intoData Security, you’ll masterdisk encryption with LUKS, ensuring data protection at rest. You’ll also learn to encrypt individual files withGPG, and secure network traffic usingSSHto prevent data breaches.
TheSecuring Servicessection empowers you with advanced techniques, including understanding and customizingSELinuxto enforce security policies. You’ll explore the concept ofchroot jailsto contain applications and minimize risks. Finally, you’ll get introduced toLXC containers, setting up and managing lightweight Linux containers for isolating services and enhancing security.
By the end of this course, you’ll possess practical, actionable knowledge to fortify your Linux systems, making you a more proficient and security-conscious Linux administrator.
Who this course is for:
- This course is designed for IT professionals, Linux system administrators, and cybersecurity enthusiasts who want to deepen their understanding of Linux security. It’s perfect for those with basic Linux command line experience who are eager to secure their systems and protect sensitive data. If you’re responsible for managing Linux servers or work in a security-focused role, you’ll find the practical, hands-on exercises and real-world examples especially valuable. Even if you’re new to Linux security, this course is structured to build your confidence and skills from the ground up. Let’s make your systems more secure together!
