Explanation

Either IP spoofing or MAC spoofing attacks can be performed to hide the identity in the network. MAC spoofing is a hacking technique of changing an assigned Media Access Control (MAC) address of a networked device to a different one. The changing of the assigned MAC address may allow the bypassing of access control lists on servers or routers, either hiding a computer on a network or allowing it to impersonate another computer. MAC spoofing is the activity of altering the MAC address of a network card. Answer: A is incorrect. DNS cache poisoning is a maliciously created or unintended situation that provides data to a caching name server that did not originate from authoritative Domain Name System (DNS) sources. Once a DNS server has received such non-authentic datA, Caches it for future performance increase, it is considered poisoned, supplying the non-authentic data to the clients of the server. To perform a cache poisoning attack, the attacker exploits a flaw in the DNS software. If the server does not correctly validate DNS responses to ensure that they are from an authoritative source, the server will end up caching the incorrect entries locally and serve them to other users that make the same request. Answer: B is incorrect. In a distributed denial of service (DDOS) attack, an attacker uses multiple computers throughout the network that has been previously infected. Such computers act as zombies and work together to send out bogus messages, thereby increasing the amount of phony traffic. The major advantages to an attacker of using a distributed denial-of-service attack are that multiple machines can generate more attack traffic than one machine, multiple attack machines are harder to turn off than one attack machine, and that the behavior of each attack machine can be stealthier, making it harder to track down and shut down. TFN, TRIN00, etc. are tools used for
