Step 1: Identify the types of denial-of-service attacks.
A denial-of-service (DoS) attack is a type of cyber attack where the attacker seeks to make a machine, network, or service unavailable to its intended users by temporarily or indefinitely disrupting services. There are two common types of DoS attacks: Smurf Attack and Syn Flood.
Step 2: Define Smurf Attack.
A Smurf Attack is a form of DoS attack that exploits the Internet Protocol (IP) and ICMP (Internet Control Message Protocol) to flood a network with traffic. The attacker sends a ping request to a broadcast address, with the source address spoofed as the victim's IP address. As a result, all hosts on the network respond to the broadcast address, overwhelming the victim's network with traffic.
Final Answer
The two common denial-of-service attacks are Smurf Attack and Syn Flood. A Smurf Attack exploits the IP and ICMP to flood a network with traffic, while a Syn Flood exploits the TCP three-way handshake process to overwhelm a server with half-open connections. Rootkits and botnets are not types of DoS attacks but rather tools used by attackers to carry out such attacks.
