Here are a few tips to secure your rcon :
#1 - Choose a complicated rcon like "aDhT18vHd9" instead of a simple one. Mix letters and numbers, even some special characters if you like.
#2 - In your server.cfg use penalties against players trying to enter random rcon passwords :
Code: Select all
#3 - Protect your rcon against exploits installing plugins (check Game Mods > Plugins). There are some like "Rcon lock" or "Ironwall" doing the job.
