Which of the following are examples of DDoS attacks?

Some common examples of DDoS attacks are UDP flooding, SYN flooding and DNS amplification.

How many types of DDoS attacks are there?

There are three basic categories of attack: volume-based attacks, which use high traffic to inundate the network bandwidth. protocol attacks, which focus on exploiting server resources. application attacks, which focus on web applications and are considered the most sophisticated and serious type of attacks.

How do DDoS attacks work quizlet?

DDoS attacks use compromised systems as intermediaries; reflector and amplifier attacks use normally-functioning network systems as intermediaries. attacker sends packets to a known service on the intermediary network with a spoofed source address that matches the actual target system.

What is the purpose of DDoS attacks?

Distributed denial-of-service attacks target websites and online services. The aim is to overwhelm them with more traffic than the server or network can accommodate. The goal is to render the website or service inoperable. The traffic can consist of incoming messages, requests for connections, or fake packets.

What are the most common types of DDoS attacks?

Volumetric attacks are by far the most common type of DDoS attacks. According to Arbor Networks, 65\% of DDoS attacks are volumetric in nature. Although volumetric attacks are characterized by an enormous amount of traffic (sometimes in excess of 100 Gbps), they do not mandate large amount of traffic to be generated by the hackers themselves.

What is a denial-of-service (DoS) attack?

As the name suggests, a Denial-of-Service (DoS) attack is intended to render any type of service in-accessible. For example, shutting down access to an external-facing online asset like an ecommerce site constitutes a denial-of-service.

What is an example of a protocol based attack?

Protocol-based attacks primarily focus on exploiting a weakness in Layer 3 or Layer 4 of the OSI layer. The most common example of a protocol-based DDoS attack is the TCP Syn Flood, wherein a succession of TCP SYN requests directed towards a target can overwhelm the target and make it unresponsive.
