systemctl disable* Firewall Configuration:
* Using
ufw or iptables to limit exposed ports* SSH Best Practices:
* Disable root login, change default port, use key-based auth
Review Questions:

Lunch Study Guide: Capstone Project Overview
Project Requirements
Objective:
* Apply all skills and tools learned throughout the 30-day course to complete a comprehensive Linux-based capstone project.
* The project should simulate a real-world environment and demonstrate competence in system setup, automation, and security.
Requirements Checklist:
* Deploy a virtual or physical Linux machine (preferably a VM for safe testing).
* Secure the system (disable unnecessary services, configure firewall, harden SSH).
* Automate tasks with scripts, cron, or configuration management tools.
* Use Docker or Ansible/Puppet for service deployment.
* Ensure logging and monitoring is active (systemd, journald, custom scripts, Lynis).
* Include backup and recovery solutions.
Planning the Project
Steps to Plan:
1. Define Scope: Choose whether to simulate a web server setup, a secure DevOps pipeline, or a workstation hardening project.
2. List Components: Identify what needs to be installed/configured (e.g., Nginx, Docker, Ansible, cron jobs).
3. Draft a Timeline: Allocate time for installation, configuration, testing, and documentation.
4. Choose Tools: Select tools like Docker, Ansible, or bash scripting based on what best demonstrates your skills.
5. Set Milestones: Break the project into stages: initial setup, automation, hardening, testing, documentation.
Team Collaboration (If Applicable)
Best Practices:
* Use GitHub or GitLab for version control and collaboration.
* Assign roles: e.g., security lead, automation engineer, documentation lead.
* Communicate clearly using comments and markdown README files.
* Use tools like
tmux, ssh, or VS Code Live Share for real-time pairing (optional).Capstone Tips
* Focus on clarity, completeness, and functionality.
* Don't try to use every tool—use the ones that show your understanding and capability.
* Document each step: what you did, why you did it, and the outcome.
* Include screenshots or logs as evidence of system behavior.
Review Questions
* What tools did you choose and why?
* How did you ensure system security?
* What automation tasks were included?
* How would you improve your setup if given more time?
