- Container and orchestration APIs give full control of hosts: require mutual TLS and RBAC.
- Never expose them to the Internet.
- Rotate tokens and certificates and audit who has access.
Port 5302: HA cluster configuration
Port 5302 is assigned by IANA to hacl-cfg (HA cluster configuration).

Is port 5302 dangerous?
We have no specific security note for port 5302. Its risk depends on the program actually listening on it. General advice for devops, cloud & containers services:
IANA registry entries for port 5302
| Service | Port | Transport | Description | Reference | Updated |
|---|---|---|---|---|---|
| hacl-cfg | 5302 | TCP, UDP | HA cluster configuration | - | - |
// source: IANA service name and port number registry
Which program uses port 5302, and is it reachable?
Linux
sudo ss -ltnup 'sport = :5302' # process listening on 5302
sudo lsof -nP -i :5302macOS
sudo lsof -nP -i :5302
Windows (PowerShell)
Get-NetTCPConnection -LocalPort 5302 -State Listen | Select LocalAddress, OwningProcess Get-NetUDPEndpoint -LocalPort 5302 netstat -ano | findstr :5302
From another machine
nmap -p 5302 -sV <host> sudo nmap -sU -p 5302 <host> nc -zv <host> 5302
Block it in the firewall
sudo ufw deny 5302/tcp # Linux (ufw) New-NetFirewallRule -DisplayName "Block 5302" -Direction Inbound -LocalPort 5302 -Protocol TCP -Action Block # Windows
What is port 5302 used for?
Port 5302 is assigned by IANA to hacl-cfg (HA cluster configuration).
Is port 5302 TCP or UDP?
Port 5302 is registered for TCP and UDP.
Is it safe to open port 5302?
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. Container and orchestration APIs give full control of hosts: require mutual TLS and RBAC.
How do I check if port 5302 is open?
On Linux run "ss -ltnup 'sport = :5302'", on macOS "lsof -nP -i :5302", and on Windows "netstat -ano | findstr :5302" to see the local process. From another machine, "nmap -p 5302 <host>" shows whether it is reachable.
