IDS/Firewall Evasion Techniques - Packet Fragmentation
SYN/FIN Scanning Using IP Fragments The TCP header is split into several packets so that the packet filters are not able to detect what the packets are intended to do. (P.354/338)
C is Correct.
It is not a new scanning method but a modification of the earlier methods
- The TCP header is split up into several packets so that the packet filters are not able to detect what the packet intend to do
Attackers send SYS/FIN (Small IP Fragments) + port (n)
The target reply RST (if port is closed)
