DDoS attacks are typically launched from a botnet, which is a network of compromised devices. This also increases the difficulty of attribution, as the true source of the attack is harder to identify. The goal of a DDoS attack is to overwhelm a system's resources or bandwidth, making it di...
What is a DDoS botnet? Common DDoS attacks Flood attacks DDoS attack tools Glossary theNET Learning Objectives After reading this article you will be able to: Learn how the OSI model works Understand what layer 7 is in the OSI Model Understand why layer 7 is called the "application layer" ...
Lower application levels of the OSI model are concerned with ensuring that data gets where it needs to go and is formatted appropriately. Layer 7 is where applications that interact with the user operate. For instance, when browsing the web, a user will be using the HTTPS web protocol to co...
A distributed denial-of-service (DDoS) attack targets websites and servers by disrupting network services. Learn about DDoS attacks and how to prevent them.
Application layer attacks The goal of the attack: Sometimes referred to as a layer 7 DDoS attack (in reference to the 7th layer of the OSI model), the goal of these attacks is to exhaust the target’s resources to create a denial-of-service. The attacks target the layer where web pages...

This type of DDoS attack is popular because the application layer require...
Some DDoS attacks use Layer 3 protocols, especially ICMP, to take down targeted servers or websites. Learn more about L3 DDoS attacks and how they work.
An HTTP flood is a type of application-layer attack and is similar to constantly refreshing a web browser on different computers all at once. In this manner, the excessive number of HTTP requests overwhelms the server, resulting in a DDoS. DDoS Attack Prevention Even if you know what is ...
The magnitude of Layer 7 attacks is measured in Requests per second (Rps). Mitigating DDoS attacks Dealing with DDoS attacks requires a number of different tactics, which include firewalls and other protection layers and should include strategic plans in the event of an attack. Some common ...
