DDoS attacks are becoming more prolific, powerful, vicious, and highly expensive. And traditional DDoS protection solutions that depend on traditional WAFs, network firewalls, signature analysis, and rate-limiting are simply failing to protect against these latest versions of DDoS attacks.
Today, advanced, multi-layered cloud DDoS protection services that use futuristic technologies such as AI, ML, automation, predictive analytics, and so on are necessary for effective, ongoing, and holistic protection against the latest attacks.
Why is it so? What features and capabilities should the DDoS protection solution provide? Read on to know the answers.
While the idea behind DDoS attacks is to disrupt services and prevent legitimate users from accessing the targeted website/ network/ application, it is often also used as a smokescreen for other malicious activities. In the recent past, especially since the onset of the global pandemic, this trend of blended attacks saw a sharp rise. Ransom-motivated DDoS attacks increased by 29% in 2021 as opposed to 2020.
A few years back, attackers would use a single attack vector to orchestrate DDoS attacks. However, the number of complex attacks using four or more vectors has increased, amplifying the complexity of DDoS attacks. Several attacks in the last year used 27-31 vectors in a single attack. The challenge in protecting against such denial-of-service attacks is that even when one of the vectors is shut down or disrupted, the others will keep sending requests to the server to overwhelm it. So, multi-vector attacks become harder to disrupt without the right DDoS protection solution.
Several newer, nastier attacks have emerged in the past few years. Attacks are not just volumetric; there is strong growth in sneaky application-layer attacks, network attacks, and slow-and-low attacks. Attacks could last just a few minutes, but the impact on the organization can be long-lasting, financially and reputationally. The highly targeted carpet-bombing attacks against ISPs, cloud service providers, hosting providers, carriers, VPN services, etc., have grown too. Attackers also use several evasion techniques to avoid detection by anti-DDoS solutions. Advanced, managed DDoS protection solutions are necessary to effectively detect and stop these attacks.
While botnets continued to play a central role in orchestrating DDoS attacks, new and lethal botnets such as Meris have emerged. With a botnet size of 250,000 compromised devices, Meris was used to orchestrate massive application-layer attacks in H2 2021. One of the attacks was against a US-based financial institution wherein a high of 17.2 million requests per second (RPS) was reached. In another attack, Meris botnet achieved 21 million RPS against a Russian bank through its cloud-hosting service.
Without next-gen, intelligent, and cloud DDoS protection solutions, it is close to impossible to detect such botnet activities and stop them before they spiral into severe attacks.
Today, source codes, botnets, DDoS toolkits, etc., are readily available to attackers for hire. So, it is much easier and seamless to orchestrate DDoS attacks now.
The best DDoS protection and mitigation solutions swiftly swing into action since the attacks may last for a much shorter duration and can cause severe damage. To achieve this, these solutions use a combination of AI with self-learning capabilities, intelligent automation, predictive analytics, and other advanced technologies to find unusual and potentially-damaging activities faster than any traditional solution.
The DDoS protection solution must secure the application against volumetric, network, and application-layer attacks and provide comprehensive coverage against all kinds of DDoS attacks. It must be instantaneous and always-on.
The solution must monitor all incoming traffic and requests while allowing only legitimate users to access the application/ network/ systems. Instead of simply using signature-based detection, the solution must use advanced techniques such as behavioral analysis, granular traffic inspection, heuristic analysis, etc.
The Bottomline
If your DDoS protection solution does not have the above-discussed capabilities, it will be ineffective against the latest breed of DDoS attacks. And your IT infrastructure will be left open to highly damaging attacks!
