🔒 Security Best Practices - QBCore Guide for FiveM
Introduction
This tutorial turns 🔒 Security Best Practices into a clean, developer-friendly guide for QBCore/FiveM. You will follow a step-by-step flow, copy the relevant code patterns, and learn the “why” behind the setup.
Requirements
- QBCore installed and running on a dev server
- Basic Lua knowledge and comfort reading FiveM patterns
- A test workflow for iterating safely (dev server, not production)
- Optional: a code editor with Lua/FiveM helpers (VS Code recommended)
Step-by-Step Guide
Step 1: Security Overview
In this step, you will apply the security overview concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.
Step 2: Security Threat Categories
In this step, you will apply the security threat categories concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.
Step 3: Security Framework
In this step, you will apply the security framework concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.
Step 4: Defense in Depth
In this step, you will apply the defense in depth concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.
Step 5: Zero Trust Model
In this step, you will apply the zero trust model concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.
Step 6: Immediate Security Actions
In this step, you will apply the immediate security actions concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.
Step 7: Critical Security Checklist
In this step, you will apply the critical security checklist concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.
Step 8: Quick Hardening Steps
In this step, you will apply the quick hardening steps concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.
Code Example
# Update system packages
sudo apt update && sudo apt upgrade -y
# Configure basic firewall
sudo ufw enable
sudo ufw allow 22/tcp # SSH
sudo ufw allow 30120/tcp # FiveM
sudo ufw allow 30120/udp # FiveM UDP
sudo ufw deny 3306/tcp # Block MySQL external access
# Secure SSH
sudo sed -i 's/#PermitRootLogin yes/PermitRootLogin no/' /etc/ssh/sshd_config
sudo sed -i 's/#PasswordAuthentication yes/PasswordAuthentication no/' /etc/ssh/sshd_config
sudo systemctl restart ssh
# Set up fail2ban
sudo apt install fail2ban -y
sudo systemctl enable fail2banTips & Best Practices
- Keep authority on the server: validate inputs before money/database operations.
- Start with one resource/module at a time, then refactor after you verify it works.
- Use callbacks for request/response flows and events for push/UX updates.
- When you run loops, avoid freezes: always yield with Wait() (client/server) and cache hot values.
What You Will Learn
This Optimization tutorial focuses on practical outcomes for FiveM scripting and QB Core development. By following the steps in 🔒 Security Best Practices - QBCore Guide for FiveM, you will understand how the topic fits into a real server workflow and how to apply it safely.
You will learn the reasoning behind the implementation choices (especially for advanced topics), so you can make the same decisions again for future resources. The goal is to reduce trial-and-error, improve consistency across updates, and help your team ship changes without breaking gameplay.
- Identify the correct use case for this approach in a QB Core or FiveM environment
- Implement the key concepts with an install-ready workflow
- Validate compatibility and avoid common setup conflicts
- Apply best practices to keep your server stable over time
Why This Matters
When scripts, configs, and documentation are aligned with your server architecture, you reduce maintenance overhead. That means fewer upgrade surprises, faster onboarding for new admins, and a more reliable experience for your players.
