Checklist Summary:

The F5 NGINX Security Technical Implementation Guide (STIG) is published as a tool to improve the security of Department of Defense (DOD) information systems. This document is meant for use in conjunction with other STIGs, such as the Web Server SRG and appropriate operating system STIGs. NGINX is a powerful open-source software used for web serving, reverse proxying, caching, load balancing, media streaming, and more. It is known for its high performance, stability, and ability to handle many concurrent connections efficiently. NGINX was initially designed as a web server to maximize performance and stability. NGINX has evolved from a web server to a comprehensive platform for app delivery, optimization, and security in Kubernetes environments. This STIG was developed for the F5 NGINX Plus enterprise offering but still applies to the open-source NGINX application.
