Control Trollers or attacks

I will be making a jitsi-meet server next week and I was just wondering if you have created any type of control panel for staff?
Anyways to protect against trolling or attacks on your rooms of server?
Or anyway commands to block countries would be better.
Anything I need to know before I do it?
My project is UK based for the NHS so I’m very interested in the security of this client.
Banning users or IPs, is there anything to control security issues that may turn up.

Many thanks in advance and I do wish you well :wink:
