nginx
A widely used web server and reverse proxy. Its own security depends heavily on manual configuration choices such as TLS settings, security headers and disabling directory listing.
Why nginx-specific hardening matters
nginx handles TLS termination and often sits directly in front of the application, which makes its own configuration, not just the application behind it, a meaningful part of a server's overall attack surface.
A commonly overlooked setting
server_tokens, which by default reveals the exact nginx version in every HTTP response, gives attackers a head start on identifying which known vulnerabilities might apply, for essentially no operational benefit.
Frequently asked questions
Is nginx inherently more or less secure than other web servers?
Security depends far more on configuration than on the choice of web server itself; nginx is widely used and well documented, which makes secure configuration comparatively easy to get right.
Does nginx handle TLS/SSL directly?
Yes, nginx is commonly configured to terminate TLS itself, handling encryption and certificate validation before passing plain traffic to the application behind it.
What is one quick win for hardening a default nginx install?
Disabling server_tokens and adding the standard security headers, both of which take minutes to configure and meaningfully reduce the information exposed to an attacker.
