01 Security

Is port 362 dangerous?

We have no specific security note for port 362. 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 362, and is it reachable?

Linux

sudo ss -ltnup 'sport = :362'      # process listening on 362
sudo lsof -nP -i :362

macOS

sudo lsof -nP -i :362

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 362 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 362
netstat -ano | findstr :362

From another machine

nmap -p 362 -sV <host>
sudo nmap -sU -p 362 <host>
nc -zv <host> 362

Block it in the firewall

sudo ufw deny 362/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 362" -Direction Inbound -LocalPort 362 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 362 used for?

Port 362 is assigned by IANA to srssend (SRS Send).

Is port 362 TCP or UDP?

Port 362 is registered for TCP and UDP.

Is it safe to open port 362?

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 362 is open?

On Linux run "ss -ltnup 'sport = :362'", on macOS "lsof -nP -i :362", and on Windows "netstat -ano | findstr :362" to see the local process. From another machine, "nmap -p 362 <host>" shows whether it is reachable.
