Evading IDS (Fragmented IP Packets
In order to scan a network , we have to bypass the firewall or IDS systems . However , I found that the old techniques of nmap / P0f do not work most of the time with the strong & new firewalls or IDS . My question is there a way to craft fragmented packets with certain time delays that can bypass these obstacles and do not trigger any alarms.
I have been using the usual scanning technique/ fragmentation , but want to improve it as to be able to customize special bypassing packets.
