01 Security

Is port 1315 dangerous?

We have no specific security note for port 1315. Its risk depends on the program actually listening on it. General advice for other services services:

  • Close the port if nothing on the host needs it.
  • Identify the process that listens on it (commands below) before opening it in a firewall.
  • Expose a service only to the networks that use it.

03 Check it

Which program uses port 1315, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1315'      # process listening on 1315
sudo lsof -nP -i :1315

macOS

sudo lsof -nP -i :1315

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1315 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1315
netstat -ano | findstr :1315

From another machine

nmap -p 1315 -sV <host>
sudo nmap -sU -p 1315 <host>
nc -zv <host> 1315

Block it in the firewall

sudo ufw deny 1315/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1315" -Direction Inbound -LocalPort 1315 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1315 used for?

Port 1315 is assigned by IANA to els (E.L.S., Event Listener Service).

Is port 1315 TCP or UDP?

Port 1315 is registered for TCP and UDP.

Is it safe to open port 1315?

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. Close the port if nothing on the host needs it.

How do I check if port 1315 is open?

On Linux run "ss -ltnup 'sport = :1315'", on macOS "lsof -nP -i :1315", and on Windows "netstat -ano | findstr :1315" to see the local process. From another machine, "nmap -p 1315 <host>" shows whether it is reachable.
