CEH Scanning Methodology - Scanning Beyond IDS

IDS Evasion Techniques

  • Use fragemented IP packets.
  • Spoof your IP address when launching attacks and sniff responses from server.
  • Use source routing (if possible).
  • Connect to proxy servers or compromised trojaned machine to launch attacks.


SYN/FIN Scanning Using IP Fragments (-f)

  • It is not a new scanning method but a modification of the earlier methods.
  • The TCP header is split into several packets so that the packet filters are not able to detect what the packets intend to do.
