![]() IPsec runs in two modes: Transport and Tunnel. Internet security protocol (IPSEC) has the ability to encrypt the packet on some shared key between the two parties involved in communication. This encryption can be provided by using protocols such as IPSEC, SSL, SSH etc. Network level hijacks can be prevented by Ciphering the packets so that the hijacker cannot decipher the packet headers, to obtain any information which will aid in spoofing. To defend a network with session hijacking, a defender has to implement both security measures at Application level and Network level. If attacker is not able to sniff packets and guess the correct sequence number expected by server, brute force combinations of sequence number can be tried. In implementing this technique, attacker has to obtain the IP address of the client and inject his own packets spoofed with the IP address of client into the TCP session, so as to fool the server that it is communicating with the victim i.e. This is a technique used to gain unauthorized access to the computer with an IP address of a trusted host. Spoofing is pretending to be someone else.
