What is ICMP Smurf attack?

An ICMP for smurf attack is a form of DDoS attack that overloads network resources by broadcasting ICMP echo requests to devices across the network. Devices that receive the request respond with echo replies, which creates a botnet situation that generates a high ICMP traffic rate.

What protocol is used for a Smurf attack?

The smurf attack is a form of brute force attack that uses the same method as the ping flood, but directs the flood of Internet Control Message Protocol (ICMP) echo request packets at the network’s router.

Which two attack categories does the Smurf attack belong to?

There are two main types of smurf attacks: basic and advanced. Basic Smurf Attack: When the targeted network is flooded with a seemingly endless array of ICMP request packets, a basic smurf attack is successful.

What are the types of DDoS attacks?

Broadly speaking, DoS and DDoS attacks can be divided into three types:

  • Volume Based Attacks. Includes UDP floods, ICMP floods, and other spoofed-packet floods.
  • Protocol Attacks. Includes SYN floods, fragmented packet attacks, Ping of Death, Smurf DDoS and more.
  • Application Layer Attacks.

How do Smurf attacks work?

A smurf attack is a form of a DDoS attack that causes packet flood on the victim by exploiting/abusing ICMP protocol. When deployed, large packets are created using a technique called “spoofing”. The phony source address that is now attached to these packets becomes the victim, as their IP is flooded with traffic.

What are three types of access attacks choose three?

27. A port scan is classified as what type of attack?

  • access attack.
  • Denial of Service attack.
  • reconnaissance attack*
  • spoofing attack.

How does ICMP flood work?

Conclusion. Ping floods or ICMP flood attack is a denial-of-service attack that restricts legitimate access to devices on a network. Such an attack works by overwhelming the victim device with ICMP request (ping) commands over the network, making it impossible for the victim to send ICMP responses in time.

What are the most commonly employed ICMP message types?

Commonly used ICMP types are echo request and echo reply (used for ping) and time to live exceeded in transit (used for traceroute).
