Server-side security risks

[CivicXFB]

I have found that if my MultiPaper port is compromised, it is possible that they could open their own server through the compromised port and incorporate it into MultiPaper, which could lead to some people creating exploits to access resources through this vulnerability. My suggestion is to add an authentication key to Multipaper-master to allow merging into Multipaper-master when the key is the same, although this is something I have not experimented with.

A simple firewall is used to prevent unwanted access to server ports. Bungeecord's official firewall guide is linked here: https://www.spigotmc.org/wiki/firewall-guide/
