# Server Recommended Security Measures

1. The simplest one but most effective, enable **Whitelist**! Add allowed players either via the [GUI](https://servers.legendaryrttextures.com/server-management/ingame#server-gui-manager) or by executing `/whitelist add <playername>` . Then enable the whitelist via the [GUI](https://servers.legendaryrttextures.com/server-management/ingame#server-gui-manager) or by executing `/whitelist on`. To remove a player from the whitelist do `/whitelist remove <playername>` or use the [GUI](https://servers.legendaryrttextures.com/server-management/ingame#server-gui-manager) once again.
2. Minecraft has some small vulnerabilities and dupe glitches that might be exploited by some players depending on your server version. You can take control of them and prevent them by using the plugin [#dupe-fixes-illegal-stack-remover-2.9.9](https://servers.legendaryrttextures.com/plugins/list#dupe-fixes-illegal-stack-remover-2.9.9 "mention"). You can configure it to fit your needs after installing it and using `/config` to navigate to the plugin's folder and modify the configuration file.
3. This is going impact your server's performance but if you believe it is required we provide 3 AntiCheat plugins to block cheaters. These plugins can be installed from the [GUI Plugin Installer](https://servers.legendaryrttextures.com/server-management/ingame#server-gui-manager) and the 2 of them which are free can be configured with the [`/config`](https://servers.legendaryrttextures.com/server-management/ingame#server-gui-manager) command. You can find more info about them here:\
