Alert if a port is opened#156

I have a server that is fully firewalled. I want to know if any specific ports are opened to the internet. Currently you can only receive an alert if a port is closed.

This is helpful for monitoring security on vendors. For example, our website provider updates their software and ports will be opened that have been closed as part of security effort. We would like to be notified when they are open, as they normally should be closed. The feature would work very similar to how you have it, just the opposite. So, when a port is open, it is green and when it is closed, it is red.

Another example would be that every IIS installation hosts a branding webpage. See example at: https://port135.com/vulnerability-remove-the-default-page-or-stop-disable-the-iis-server/

This webpage should normally be disabled. However, an upgrade to IIS may re-enable it again. I would like to be notified when this is up, as that is the alerting condition for us. Then we can go and close it.

Basically a simple NOT logic.

This would be incredibly useful.

I also need this!!

It could also work if the negative keyword check wouldn’t fail at timeout.

Nice & easy feature!
