curiousity question - port scanning


New Member
Since I switched to cPanel, I've been getting messages about my system that I didn't get under Plesk. Some of these indicates to me that there are constant attempts to hack my system. I think it interesting to see where some of these attempts come from. It concerns me, however, when such an attempt comes from the USA. I'd like to be able to identify who the party is and be able to find out if this port scanning is legitimate for some reason or another. The header in a message I get rather frequently is: blocked for port scanning. Does anybody know who these folks are?
