In this type of attack, the intruder re-routes data traffic from a network device to a personal machine. This diversion allows an attacker to gain access to critical resources and user credentials, such as passwords, and to gain unauthorized access to critical systems of an organization. Pick the best choice below.
Correct Answer: B
Explanation/Reference:
Network address hijacking allows an attacker to reroute data traffic from a network device to a personal computer.
Also referred to as session hijacking, network address hijacking enables an attacker to capture and analyze the data addressed to a target system. This allows an attacker to gain access to critical resources and user credentials, such as passwords, and to gain unauthorized access to critical systems of an organization.
Session hijacking involves assuming control of an existing connection after the user has successfully created an authenticated session. Session hijacking is the act of unauthorized insertion of packets into a data stream. It is normally based on sequence number attacks, where sequence numbers are either guessed or intercepted.
The following are incorrect answers:
Network address translation (NAT) is a methodology of modifying network address information in Internet Protocol (IP) datagram packet headers while they are in transit across a traffic routing device for the purpose of remapping one IP address space into another. See RFC 1918 for more details.
Network Address Supernetting There is no such thing as Network Address Supernetting. However, a supernetwork, or supernet, is an Internet Protocol (IP) network that is formed from the combination of two or more networks (or subnets) with a common Classless Inter-Domain Routing (CIDR) prefix. The new routing prefix for the combined network aggregates the prefixes of the constituent networks.
Network Address Sniffing This is another bogus choice that sound good but does not even exist.
However, sniffing is a common attack to capture cleartext password and information unencrypted over the network. Sniffier is accomplished using a sniffer also called a Protocol Analyzer. A network sniffers monitors data flowing over computer network links. It can be a self-contained software program or a hardware device with the appropriate software or firmware programming. Also sometimes called "network probes" or "snoops," sniffers examine network traffic, making a copy of the data but without redirecting or altering it.
