Summary
BungeeGuard is a security-enhancing plugin for BungeeCord servers in Minecraft, which are vulnerable by default. It introduces a secret authentication token to the login handshake on the proxy, verifying that backend login handshakes contain authorized tokens. This straightforward solution prevents malicious users from circumventing the proxy and connecting with arbitrary UUIDs or usernames. Additionally, it simplifies security management by eliminating the need for complex firewall rules.
