- Bind the service to localhost or a private network, never to a public address.
- Enable authentication, use per-application accounts and require TLS.
- Watch for exposed Docker ports: publish them on 127.0.0.1 only.
Port 3630: C&S Remote Database Port
Port 3630 is assigned by IANA to cs-remote-db (C&S Remote Database Port).

Is port 3630 dangerous?
We have no specific security note for port 3630. Its risk depends on the program actually listening on it. General advice for databases & caches services:
IANA registry entries for port 3630

Which program uses port 3630, and is it reachable?
Linux
sudo ss -ltnup 'sport = :3630' # process listening on 3630
sudo lsof -nP -i :3630macOS
sudo lsof -nP -i :3630
Windows (PowerShell)
Get-NetTCPConnection -LocalPort 3630 -State Listen | Select LocalAddress, OwningProcess Get-NetUDPEndpoint -LocalPort 3630 netstat -ano | findstr :3630
From another machine
nmap -p 3630 -sV <host> sudo nmap -sU -p 3630 <host> nc -zv <host> 3630
Block it in the firewall
sudo ufw deny 3630/tcp # Linux (ufw) New-NetFirewallRule -DisplayName "Block 3630" -Direction Inbound -LocalPort 3630 -Protocol TCP -Action Block # Windows
What is port 3630 used for?
Port 3630 is assigned by IANA to cs-remote-db (C&S Remote Database Port).
Is port 3630 TCP or UDP?
Port 3630 is registered for TCP and UDP.
Is it safe to open port 3630?
It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Bind the service to localhost or a private network, never to a public address.
How do I check if port 3630 is open?
On Linux run "ss -ltnup 'sport = :3630'", on macOS "lsof -nP -i :3630", and on Windows "netstat -ano | findstr :3630" to see the local process. From another machine, "nmap -p 3630 <host>" shows whether it is reachable.
