Doing something with a hackers IP
Ok, when I find out a person who is trying to break into my computer via one of the security systems i have on my computer (norton antivrius or zone alarm),and i get their ip and what they were doing, ie port scanning or something like that, how can i take it to the next step?
how do i know if the port scanning was malicious?
how do i find out an approximate address of the hacker, just so i can warn them to stop?
basically i wnna know what i can do when i find out a hackers IP and what they were doing (lets say port scanning) how i can find out if this was actually a malicious attack and how i can track where the hacker is coming from.
