It is not good to expose your server information. Follow the steps given to disable Apache header information.

Edit your main Apache configuration file, and you can find the following directives.

vim /etc/httpd/conf/httpd.conf
ServerSignature On
ServerTokens OS


Please change it to as shown below.

ServerSignature off
ServerTokens Prod


You can find some information about the ServerSignature and ServerTokens directives below.


ServerSignature: This directive allows the configuration of a trailing footer line under server-generated documents ( error messages, mod_proxy ftp directory listings, mod_info output, …etc.). The Off setting will suppress the footer line.


ServerTokens: This directive controls whether the Server response header field sent back to clients includes a description of the generic OS-type of the server as well as information about compiled-in modules.


ServerTokens Prod[uctOnly]
Server sends (e.g.): Server: Apache
ServerTokens Major
Server sends (e.g.): Server: Apache/2
ServerTokens Minor
Server sends (e.g.): Server: Apache/2.0
ServerTokens Min[imal]
Server sends (e.g.): Server: Apache/2.0.41
ServerTokens OS
Server sends (e.g.): Server: Apache/2.0.41 (Unix)
ServerTokens Full (or not specified)
Server sends (e.g.): Server: Apache/2.0.41 (Unix) PHP/4.2.2 MyMod/1.2


This setting applies to the entire server and cannot be enabled or disabled on a virtualhost-by-virtualhost basis.

Add the below entries to disable Apache Last Modified header.

<filesMatch ".*$">
Header unset Last-Modified


Restart Apache.

/etc/init.d/httpd restart


That’s it!! You have disabled Apache header information.
