43. A flood of packets with invalid source IP addresses requests a connection on the network. The server busily tries to respond, resulting in valid requests being ignored. What type of attack has occurred?

  • TCP session hijacking
  • TCP SYN flood
  • TCP reset
  • UDP flood

Explanation: The TCP SYN Flood attack exploits the TCP three-way handshake. The threat actor continually sends TCP SYN session request packets with a randomly spoofed source IP address to an intended target. The target device replies with a TCP SYN-ACK packet to the spoofed IP address and waits for a TCP ACK packet. Those responses never arrive. Eventually the target host is overwhelmed with half-open TCP connections and denies TCP services.
