1. Presentation On IP Spoofing

2. Spoofing Is a situation in which One person or program Successfully inserts false Or misleading information in e-mail or Netnews headers.Also known as header forgery.

10. It guarantee delivery and ordering,but relies upon IP to move packets proper destination.

11. Port number are used to express source and destination.

13. Normally, the source address is incorrect.

14. Lying about the source lets an attacker assume a new identity.

15. Because the source address is not the same as the attacker’s address, any replies generated by

17. Attacker must have an alternate way to spy on traffic/predict response.

19. Attacker normally within a LAN/on the communication path between server and client.

21. Session Hijack

23. The victim-Tsutomu Shinomura

26. He flooded the server to prevent communication between it and the workstation

27. Used math skillz to determine the TCP sequence number algorithm(i.e.add 128000)

28. This allowed Mitnick to open a connection without seeing the workstation outgoing sequence numbers and without the server interrupting his attack

33. With the services queue filled,legitimate user’s cannot use the service.

35. AS mentioned other in the architecture model may reveal spoofing.

36. TCP sequence numbers are often used in this manner

37. Makes if difficult to proper sequence number if the attacker is blind

38. Filtering

39. “Smart” routers can detect IP address that are outside its domain i.e. Egress filtering

42. Verification of identity of incoming packets.
