An application layer DDoS attack is where attackers target the layer 7 OSI (Open Systems Interconnection) layer.

It was not so long time ago that it was cloned alongside as a complementary solution to the WAF, as the problem became more serious and demanding, while DDoS has always been viewed as an operational problem rather than an application problem. WAF and application layer (DDoS) attacksĪpplication DDoS is a major private case for the WAF. However, what was good enough for the on-premise environment cannot be buried now at the clouds fully automated environment. They are definitely not good to protect against attacks such as credential stuffing.īoth aspects of the problem demand manpower to customize and maintain WAF in any environment.

Moreover, WAFs were never flexible against dynamic threats made by advanced botnets as were mostly made to protect from simple “SQL injection” like attacks. It seems to have been accepted not because it's good, but because there is no alternative. As for that, they were remodeled, but scaling and automation was still an issue. That actually means that classic WAF’s were not built for cloud architecture. Although, you may generate instances the fact is that it was not designed for elasticity. We can play around with server load balancing and elastic services, but the scale is not something that was initially built into the WAF. Issues with the classic WAF and the cloud Undoubtedly, they are a must for the future and survival of cloud-based WAF environments. Zenedge (now Dyn since Oracle's purchase of it) offers a WAF, which shows signs of automation needed by Oracle cloud offering, although it is not enough to make a huge difference from traditional WAF functionality, as lack a significant technological advance in covering the essential spectrum of threats much better than existing technologies.ĪI and ML are the tools used for predictive analytics. This is evident by the fact that this year Oracle purchased Zenedge, a provider of cloud-based, ML-driven cybersecurity solutions. We are beginning to see movement in the use of ML for the WAF in the cloud. Such technology may also play a crucial role in the WAF solutions, as defending against the same multi-purpose botnets. However, more AI and ML solutions are beginning to surface as a major success against distributed denial-of-service (DDoS) attacks and more specifically against the application DDoS world, which was shown by L7 Defense with its unsupervised learning approach. There are not so many artificial intelligence/machine learning (AI/ML) solutions in the cyberdefense segment of the network and application defense. The functionality that the classic WAF offers have become a matter of discontent, while next-generation WAFs, which were born as AI systems that may address such a multi-dimensional threat complexity, are quite rare. These botnets are made now by an Artificial Intelligence (AI) functionality on top of the “old” Internet of things (IoT) botnets which are becoming more and more multi-purpose in its ability to attack with different vectors. Generally speaking, there is a major disappointment at the WAF customer end because of the lack of automation, scalability, and coverage of the emerging threats which become essential as modern botnets become more and more efficient and aggressive. However, some vendors are adopting the RASP technology. It seems to be a desperate solution to replace the WAFs, as no one really likes to mix its “security appliance” inside the application code, which is exactly what the RASP vendors are currently offering to their customers.

It is considered that the runtime application self-protection is a shortcut to securing software that is also compounded by performance problems.

There is now a trend to enter the mitigation/defense side into the application and compile it within the code. There have also been red flags raised from the use of the runtime application self-protection (RASP) technology. In reality, however, customers don’t buy it anymore and the WAF industry is under a major pressure as constantly failing on the customer quality perspective. It generally seems that vendors are trying to convince customers and themselves that everything is going smooth and that there is not a problem. The web application firewall (WAF) issue didn't seem to me as a big deal until I actually started to dig deeper into the ongoing discussion in this field.
