01 Security

Is port 1157 dangerous?

We have no specific security note for port 1157. Its risk depends on the program actually listening on it. General advice for databases & caches services:

  • 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.

03 Check it

Which program uses port 1157, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1157'      # process listening on 1157
sudo lsof -nP -i :1157

macOS

sudo lsof -nP -i :1157

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1157 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1157
netstat -ano | findstr :1157

From another machine

nmap -p 1157 -sV <host>
sudo nmap -sU -p 1157 <host>
nc -zv <host> 1157

Block it in the firewall

sudo ufw deny 1157/tcp                                         # Linux (ufw)

04 FAQ
What is port 1157 used for?

Port 1157 is assigned by IANA to iascontrol (Oracle iASControl).

Is port 1157 TCP or UDP?

Port 1157 is registered for TCP and UDP.

Is it safe to open port 1157?

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 1157 is open?

On Linux run "ss -ltnup 'sport = :1157'", on macOS "lsof -nP -i :1157", and on Windows "netstat -ano | findstr :1157" to see the local process. From another machine, "nmap -p 1157 <host>" shows whether it is reachable.
