Network Attacks and Security

1. ARP poisoning is a technique used to:

• a. Overwhelm a target server with ICMP ping packers causing a DOS attack.

• b. Install malware on victim machines transforming them into zombie agents.

• c. Overwhelm a target server with ACK packers exploiting the nature of the 3 way handshake.

• d. Alter the MAC address of a computer’s ARP cache so that traffic is directed to a man-in-the-middle instead of the intended destination such as an internet router.

Which of the following is TRUE with regards to the SMURF Flood attack

• a. The attacker utilizes large volumes of SYN packets in order to flood the server.

• b. The attacker sends an ARP broadcast packet in order to flood the server with ACK packets.

• c. With the help of other computers, the attacker floods the server with ping requests.

• d. With the help of other computers, the attacker floods the server with ping replies
