Question

A malicious attacker sends a large number of SYNC segments to a server, pretending that each of them is coming from a different client by faking the source IP address in the datagram. Which type of attack is being performed in this situation?

(a) SYNC flooding attack

(b) Active attack

(c) Passive attack

(d) Denial-of-service attack

I had been asked this question by my school principal while I was bunking the class.

This interesting question is from TCP-2 topic in chapter Transport Layer of Computer Network

Answer 1

Right choice is (a) SYNC flooding attack

To explain I would say: SYNC flooding attack is a form of Denial of Service attack. Due to the overflow of SYNC segments sent to the server, the victims are not able to request for a connection to the server, thus resulting in Denial of Service.
