TCP SYN Flood attack uses the three-way handshake mechanism.1. An attacker at system A sends a SYN packet to victim at system B.2. System B sends a SYN/ACK packet to victim A.3. As a normal three-way handshake mechanism system A should send an ACK packet to system B, however, system A does not send an ACK packet to system B. In this case clientB is waiting for an ACK packet from client A.This status of client B is called _________________Select one:a. "full-open"b. "half-closed"c. "half open"d. "xmas-open"
Question
TCP SYN Flood attack uses the three-way handshake mechanism.1. An attacker at system A sends a SYN packet to victim at system B.2. System B sends a SYN/ACK packet to victim A.3. As a normal three-way handshake mechanism system A should send an ACK packet to system B, however, system A does not send an ACK packet to system B. In this case clientB is waiting for an ACK packet from client A.This status of client B is called _________________Select one:a. "full-open"b. "half-closed"c. "half open"d. "xmas-open"
Solution
The status of client B in this case is called "half open". So, the correct answer is c. "half open".
