Service Attack. How safe is Nettalk?
« on: February 27, 2017, 07:29:39 AM »
Hello

This has been going on for days but so far nothing has happened.
Nettalk webserver works still nice.
Just wonder is this a security risk?

It looks like someone is doing a port scan on your server and these are being forwarded to your web app.If so, you should have all ports on your firewall closed and only those you need open.

In my opinion, it looks like a port scan coming from IP 37.219.130.250 to any possible ports to check services.

Maybe nmap or Nessus?

I think NetTalk is not gonna have any problems handling that, but is good idea to check other possible services from your host exposed to the internet (SMTP servers, telnet or FTP servers for example), to make it more secure and peace of mind.

Cheers
