What is Nginx Server Signature?
The Nginx server signature refers to the information about the server software and its version that is included in the HTTP response headers when a client requests an Nginx server. This signature typically reveals details like the Nginx version number, which can be useful for attackers seeking to exploit known vulnerabilities associated with specific versions. To enhance security, administrators often choose to hide or change the server signature to minimize the information exposed to potential attackers. This is done by configuring the “server_tokens” directive in the Nginx configuration file, setting it to “off” to prevent the server from disclosing its version in the response headers. This practice adds a layer of security and helps reduce the risk of targeted attacks based on known vulnerabilities.
How to Change or Hide the Nginx Server Signature?
In Linux, changing or hiding the Nginx server signature consists of modifying the server tokens that are sent in the HTTP response headers. The server signature has information about the server software and its version, which can be a security perspective risk. In this article, we will see how we can change or hide the Nginx Server Signature on the Kali Linux system.
