I have utilized NGINX Ingress Controller SSL and TLS termination feature. We have done extensive SSL offloading on NGINX Ingress Controller and made the TLS configurations to match security requirements, allowing certain TLS versions while disabling others such as 1.0, 1.1, and 1.2, and allowing 1.3. The choice depends upon the application requirement. The reverse proxy capabilities of NGINX Ingress Controller in managing distributed applications is central to its main concept. We need to configure it to allow the server to access the outside world and the internet. That is achievable, and we can install and configure NGINX Ingress Controller as a reverse proxy. It can work as a load balancer, but the main part is NGINX Ingress Controller's role as a reverse proxy. If any applications need to be accessed through the proxy to the outside world, then NGINX Ingress Controller is a good product for you. I employ the IP whitelisting feature in NGINX Ingress Controller, which helps secure my application environment. In IP whitelisting, there are several options available. You can determine which IPs to block, for example, if you do not want to give access to specific regions. You can find the list of IP addresses registered in those regions and blacklist them. There is also the web application firewall (WAF) where you can create policies to identify the type of traffic trying to access the application.
