What is the difference between Layer4 and Layer7?
Layer 4 DDoS attacks refer to attacking the real network. It requires a lot of bandwidth. Imagine a store and its customers entering/exiting. We'll say the store is the host you want to attack and people are the packages you're sending to the host. What a DDoS does is literally get everyone quickly, quickly. This makes everything slower and eventually the store will be unavailable because no one will be able to enter. Layer 7 DDoS attacks refer to attacking the application layer of a server. When we say Layer 7, we are not attacking the network itself, but the real applications hosted on the network. Generally, when we talk about Layer 7 attacks, we usually talk about HTTP DDoS attacks. In the XML-RPC scenario.
