Maximizing Server Integrity: How to Set Up AntiCheat in FiveM

In the world of FiveM, maintaining server integrity is a constant challenge. With an open framework that allows modding, FiveM attracts both creative developers and malicious users looking to exploit vulnerabilities. Cheaters disrupt gameplay, ruin the experience for honest players, and can even cause long-term damage to a server’s reputation.

Setting up an effective fivem anticheat is essential to ensure fair play and prevent hackers from taking control. This guide walks you through the step-by-step process of implementing and optimizing an AntiCheat system for your FiveM server.

Understanding the Importance of AntiCheat in FiveM

Why You Need AntiCheat Protection

FiveM servers are vulnerable to various exploits, including:

• Aimbots and Wallhacks – These give players unfair aiming and vision advantages.
• God Mode and Invincibility – Players using these hacks cannot be killed, breaking game balance.
• Money and Item Duplication – Hackers exploit server loopholes to generate in-game wealth unfairly.
• Speed and Teleport Hacks – These allow players to move instantly across the map, ruining immersion.
• Server Crashes and DDoS Attacks – Malicious actors can bring down a server using scripts or excessive resource loads.

Without an AntiCheat system, your server becomes an easy target for these exploits. Implementing a strong protection mechanism ensures stability and fairness, keeping your player base engaged.

Choosing the Right AntiCheat System for Your FiveM Server

There are two main approaches to setting up an AntiCheat system in FiveM:

1. Using Prebuilt AntiCheat Solutions – Several pre-made FiveM AntiCheat scripts exist that can be installed directly into your server.
2. Developing a Custom AntiCheat Solution – For advanced users, building a custom solution allows more flexibility and better adaptation to specific server needs.

Factors to Consider When Choosing an AntiCheat

• Detection Capabilities – How effectively does it detect various hacks?
• False Positives – Does it ban legitimate players by mistake?
• Performance Impact – Does it consume too many resources and cause lag?
• Customization Options – Can you adjust settings and add rules for your server?

Step-by-Step Guide to Setting Up AntiCheat in FiveM

Step 1: Install a Reliable AntiCheat Script

There are multiple AntiCheat solutions available for FiveM. You can download one and install it directly on your server.

How to Install an AntiCheat Script

1. Download the AntiCheat script from a trusted source.
   
2. Extract the files and place them in your server’s resources folder.
   

Open your server.cfg file and add the following line:

ruby
CopyEdit
ensure AntiCheatScriptName

1. Restart your server to activate the AntiCheat system.

Step 2: Configure the AntiCheat Settings

Most AntiCheat scripts allow customization. You can modify settings to balance detection accuracy and server performance.

Key Configurations to Adjust

• Detection Sensitivity – Adjust the threshold for detecting suspicious activity.
• Ban Policy – Decide whether the system kicks or permanently bans detected cheaters.
• Whitelist Rules – Add exceptions for trusted players or custom scripts.
• Logging System – Enable logging to track all AntiCheat actions and review reports.

Step 3: Implement Server-Side Security Measures

An AntiCheat system is only part of the solution. Strengthening server-side security prevents hackers from exploiting weaknesses.

Essential Security Measures

• Enable Server-Side Script Verification – Restrict client-side script execution.
• Disable External LUA Execution – Prevent hackers from injecting their own code.
• Limit Permissions for Server Resources – Ensure only authorized users can modify critical files.
• Use Secure Database Configurations – Protect in-game economy and player data.

Step 4: Monitor and Analyze Cheat Detection Logs

Regularly reviewing logs helps in understanding how cheaters operate and refining your security measures.

How to Check Logs

1. Navigate to your AntiCheat log file (usually found in the logs folder).
2. Look for suspicious player activity.
3. Cross-check timestamps to detect patterns in hacking attempts.
4. Adjust AntiCheat configurations based on your findings.

Step 5: Regularly Update Your AntiCheat System

Hackers constantly develop new methods to bypass security. Keeping your AntiCheat system updated is crucial.

Best Practices for Updating

• Check for AntiCheat script updates weekly.
• Stay informed about new exploits in the FiveM community.
• Test updates on a separate test server before applying them to the main server.

Advanced AntiCheat Strategies

Custom Lua-Based AntiCheat Development

For experienced developers, creating a custom AntiCheat system can provide a more tailored solution.

Key Features to Include in a Custom AntiCheat

• Real-Time Player Behavior Monitoring – Track movements, damage rates, and unusual activity.
• Server Resource Integrity Checks – Scan server resources for unauthorized modifications.
• Anti-AFK System – Prevent abuse of idle mechanics.
• Automated Ban System – Instantly remove confirmed cheaters.

Using a Combination of AntiCheat Solutions

No single AntiCheat system is perfect. A multi-layered approach provides the best protection.

Combining Multiple Solutions

• Use an automated AntiCheat script for real-time detection.
• Implement manual moderation to handle edge cases.
• Run regular security audits on your server files.

Handling False Positives and Player Reports

Even the best fivem anticheat systems can occasionally ban legitimate players. Proper handling of these cases is important.

How to Reduce False Positives

• Fine-tune detection thresholds to minimize wrongful bans.
• Create an appeal system where banned players can request a review.
• Cross-check logs before enforcing permanent bans.

Encouraging Player Reports

A good AntiCheat systemworks best when combined with community reports.

How to Set Up an Effective Report System

• Create a Discord or web-based reporting system.
• Encourage players to submit video evidence.
• Have a dedicated admin team to review reports.

Conclusion

Setting up an AntiCheat system in FiveM is essential for maintaining server integrity and ensuring fair gameplay. By choosing a reliable AntiCheat solution, configuring it properly, implementing additional security measures, and regularly monitoring activity, you can significantly reduce the risk of cheaters ruining your server.
