- 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 7474: Neo4j Graph Database

Which program uses port 7474, and is it reachable?
Linux
sudo ss -ltnup 'sport = :7474' # process listening on 7474
sudo lsof -nP -i :7474macOS
sudo lsof -nP -i :7474
Windows (PowerShell)
Get-NetTCPConnection -LocalPort 7474 -State Listen | Select LocalAddress, OwningProcess Get-NetUDPEndpoint -LocalPort 7474 netstat -ano | findstr :7474
From another machine
nmap -p 7474 -sV <host> nc -zv <host> 7474
Block it in the firewall
sudo ufw deny 7474/tcp # Linux (ufw) New-NetFirewallRule -DisplayName "Block 7474" -Direction Inbound -LocalPort 7474 -Protocol TCP -Action Block # Windows
What is port 7474 used for?
Port 7474 is assigned by IANA to neo4j (Neo4j Graph Database).
Is port 7474 TCP or UDP?
Port 7474 is registered for TCP.
Is it safe to open port 7474?
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 7474 is open?
On Linux run "ss -ltnup 'sport = :7474'", on macOS "lsof -nP -i :7474", and on Windows "netstat -ano | findstr :7474" to see the local process. From another machine, "nmap -p 7474 <host>" shows whether it is reachable.
