Table 3

DNS cache poisoning attack.

ATT not in LAN; ATT must redirect the traffic to his machine.
ATT opportunity: if local DS does not have , then the request is sent to zone server:

(M1):DNS_Query (ID1, DN); dest. IP =
(M2):DNS_Query (ID2, DN); dest. IP =

DNS cache poisoning (Until IDi = ID2)

(M3):DNS_Reply (IDi, DN, IPATT); dest. IP =
(M4):DNS_Reply (ID1, DN, IPATT); dest. IP = IPC

All client HTTP traffic is sent to ATT directly

(M5):HTTP_Request (URL); dest. IP =
(M6):HTTP_Response (HTML); dest. IP = IPC
