IDP Application-Level DDoS Attack Overview
The intent of an application-level DDoS attack is to overwhelm the targeted server, such as a DNS or HTTP server, so it cannot perform its intended services. This is done by making a tremendous number of application requests from malicious bot clients that often use spoofed IP addresses.
Application-level DDoS attacks are different from traditional Layer 3 and Layer 4 DDoS attacks, such as a SYN flood. From a Layer 3 and Layer 4 perspective, the attack can appear to be legitimate transactions. Traditional Layer 3 and Layer 4 DDoS solutions can only rate limit these attacks and begin the application transactions, instead of denying the attacks.
