• Why Web Application Firewalls Can’t Stop DDoS Attacks

    Learn the three major reasons why web application firewalls and intrusion prevention systems can’t stop DDoS attacks in organizations today.

  •  
  • Firewalls, intrusion prevention systems and web application firewalls are one of the major reasons of outages within companies. According to Radware’s ERT report, security devices like IPS firewalls and web application firewalls represented 33 percent or 1/3 of all outages from all internet born DDoS attacks. There are three major reasons why web application firewalls and intrusion prevention systems can’t stop DDoS attacks.

    1. These Devices Don’t Focus on Themselves -The major reason is that devices like web application firewalls and intrusion prevention systems can’t stop DDoS attacks because their focus isn’t centered around device itself being attacked. They’re focused at inspecting throughput traffic. The idea is that they would be placed in a way, so that they would get in front of that traffic, inspect that traffic, and then pass good traffic on.
    2. These Devices Are  Stateful  - Web application firewalls and intrusion preventions systems are designed to be stateful. What we call the idea of being stateful in the technology space means being in front of that traffic. Stateful devices have don’t have a mathematical formula to be able to stop DDoS attacks. Essentially, most vendors will tell you that if there’s a DDoS problem to just get a bigger box. It’s as if you have a cruise ship as an answer to a boat that has a leak. It’s not a DDoS solution; it’s just delaying the problem.
    3. These Devices Don’t Have Resident  - The third major reason is that web application firewalls and intrusion prevention systems can’t stop DDoS attacks is because they themselves actually do not have resident. This is a very effective technology, essentially in many cases the most effective technology that you need to deploy against DDoS attacks and other cyber attacks. These are behavioral technologies, challenge and response technologies and deployment options that include something that will allow traffic to pass through that won’t allow the web application firewall, intrusion prevention system or other hardware device to be taken over. Essentially, the hardware device can be attacked and it’s hardened from an attack.

    These three elements are missing in what we call legacy DDoS security systems and are resident in next generation DDoS mitigation systems.
