Advanced Linux Administration & Security
Overview
This project builds on Fundamentals of Linux, introducing advanced administration, automation, and security techniques. You’ll explore performance monitoring, scripting, networking, security auditing, and log analysis, equipping you for real-world Linux system management.
What You Will Learn
✅ System Performance Monitoring: Using top, htop, iotop, vmstat, free
✅ Process & Service Management: systemctl, kill, nohup, tmux
✅ Advanced Bash Scripting: Automating tasks with loops, cron jobs
✅ Networking & Firewall Security: iptables, nftables, ufw, netstat, ss
✅ Security Hardening: Auditing with Lynis, configuring SELinux/AppArmor
✅ Log Analysis & Troubleshooting: Using journalctl, syslog, grep
Self-Check: Are You Ready?
Before diving into the lab, answer these:
- How do you restart a system service?
- What command shows real-time CPU and memory usage?
- How can you schedule a script to run daily?
- What firewall command would block incoming SSH?
- How do you check failed login attempts?
🎯 If you are unsure, revisit Fundamentals of Linux before continuing.
