Cloud computing has become the new norm, especially during & post- pandemic world. With businesses moving online, cloud security is a major concern for cloud storage users & providers.  Insecure APIs, DDoS attacks, sensitive information breaches are the few major threats challenging industries including healthcare, e-commerce, government, finance, and even education.

Employees’ personal information to company’s confidential details, everything is just a click away for AI expert hackers. With advancements to security technology, cyber-attacks are also getting advanced and AI-enabled. Organizations these days have to be extra careful with selecting the most appropriate protection for their web security.  In many cases, minute mistakes like misconfiguration and inadequate change control can also lead to data leakage and exposure to cyber threats.

To curb all such cloud-related issues, Kubernetes WAF is one of the latest container orchestration systems that provide API protection and automation without breaking down cloud deployment. It is deployed as a micro service in addition to other applications, where the cloud traffic automatically passes through the Docker and Kubernetes ecosystem before actually entering the real cloud database. It works on container-based applications where if a container is overloaded or burdened, Kubernetes balances the flow by distributing the load. It has self-healing feature which enables it to remove and replace containers that do not respond or work properly. Hence, providing a resilient, agile and robust system.

A K8s web application firewall acts as the first line of defence between a company’s web applications and the internet, letting in only the authentic sources and filtering out the rest. Ultimately, protecting the company’s sensitive information over the cloud.

WAF for K8s is very useful for businesses that handle large amount of customers’ personal information and have employees database over the cloud.  The containerized web applications in such organizations are often attacked by bad actors, leaking & ruining not just the customers’ information & faith but also expose the company to various penalties from the regulatory.

Another way in which Kubernetes WAF comes into play is that, it facilitates organizations to avoid that rigorous regular web security testing conducted internally to ensure whether their data is secured and if they are safe from cyber attackers.

Moreover, WAFs are also useful in speeding up website traffic by mitigating DDoS attacks, facilitating a better user-friendly interface. As per the rules in ingress controller, Kubernetes allocates the traffic to the corresponding services making the information system safe, secure, and easy to float in order to reach its destination.
