Is port 4369 (EPMD (Erlang Port Mapper)) dangerous?

Port 4369 is classified as high risk. It is a common target for automated scanning and brute-force attacks. Restrict access to trusted IPs if exposure is necessary.

Should port 4369 be open on my firewall?

Port 4369 should only be open with strict firewall rules whitelisting trusted IP addresses. Enable rate limiting and intrusion detection systems.

What transport protocol does port 4369 use?

Apa itu Port 4369?

Port 4369 is used by EPMD (Erlang Port Mapper Daemon), a port mapper service for Erlang/OTP distributed systems. RabbitMQ and other Erlang-based applications rely on EPMD for node discovery and cluster formation. Exposure of this port can allow attackers to enumerate Erlang cluster nodes and potentially join the cluster.
