In general, information leakage exists on most web servers installed by default, one of which is PHP. PHP is one of the popular server-side html embedded languages ?). In today's challenging age, many attackers attempt to discover vulnerabilities on your server. Therefore, I will briefly describe how to hide PHP information on a Linux server.

Expose_php is enabled by default. Disable the "expose_php" parameter so that php can hide its version information.

[Root @ centos66 ~] # Vi/etc/php. ini

In your php. ini, locate the line containing expose_php and set On to Off:

Expose_php = Off

Before that, the web server header looks like this:

[Root @ centos66 ~] # Curl-I http://www.ehowstuff.com/HTTP/1.1 200 OK Server: nginx Content-Type: text/html; charset = UTF-8 Vary: Accept-Encoding X-Powered-By: PHP/5.3.3 X-Pingback: http://www.ehowstuff.com/xmlrpc.php Date: Wed, 11 Feb 2015 14:10:43 gmt x-Page-Speed: 1.9.32.2-4321 Cache-Control: max-age = 0, no-cache

After changing and restarting the Web service, php will not display the version in the web service header:

HTTP/1.1 200 OK Server: nginx Content-Type: text/html; charset = UTF-8 Vary: Accept-Encoding X-Powered-By: PHP/5.3.3 X-Pingback: http://www.ehowstuff.com/xmlrpc.php Date: wed, 11 Feb 2015 14:10:43 gmt x-Page-Speed: 1.9.32.2-4321 Cache-Control: max-age = 0, no-cache

In addition to the PHP version, the Web server also exposes the version number by default. If you are using an Apache server, refer to this article to disable Apache version Display. if you are using an Nginx server, add server_tokens off in the http segment. Please remember to restart related services for the above modifications.
