Hello Tony, I would enable those signatures, because you can check it in a better way to analyze real scans. Depending on your IDS/IPS device, you can choose to block/log if it targets more than 10 ports, for example. You can also check the kind of the event. A vuln scan can trigger a lot of signatures related to probes or some specific protocol. In additional, you can send an Abuse Letter to the owner of this IP. I hope to be helpful. Regards.

Why? Because, yes - I know that somebody may be scanning my network - but, what can I do about it? 1. Block the IP? But, what if its NAT - meaning only 1 workstation/user did the port scanning, I would be blocking all the possibly valid users behind that IP. 2. Report it to their ISP or to them? Then what? I want my IDS console not to be too cluttered that's why I'm tuning it. If its too cluttered - I might be missing out the really important alerts. What about you? How do you deal with port/vulnerability scans? Is it illegal btw? Thanks.
