01 Security

Is port 5027 dangerous?

We have no specific security note for port 5027. 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 5027, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5027'      # process listening on 5027
sudo lsof -nP -i :5027

macOS

sudo lsof -nP -i :5027

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5027 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5027
netstat -ano | findstr :5027

From another machine

nmap -p 5027 -sV <host>
sudo nmap -sU -p 5027 <host>
nc -zv <host> 5027

Block it in the firewall

sudo ufw deny 5027/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5027" -Direction Inbound -LocalPort 5027 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5027 used for?

Port 5027 is assigned by IANA to strexec-s (Storix I/O daemon (stat)).

Is port 5027 TCP or UDP?

Port 5027 is registered for TCP and UDP.

Is it safe to open port 5027?

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 5027 is open?

On Linux run "ss -ltnup 'sport = :5027'", on macOS "lsof -nP -i :5027", and on Windows "netstat -ano | findstr :5027" to see the local process. From another machine, "nmap -p 5027 <host>" shows whether it is reachable.
