DNS massive portscan
Hi,
Our firewall is reporting that more than 3000 packets have been marked as portscan attacks. Source port is 53 and it is from our ISP IP range and destination port is range between 59000 and 61000.
I have already reported to our ISP but I just want to know what security issues might be related to this sort of portscan.
