How to hide the PHP version on a Linux Server

How to hide the PHP version on a Linux Server

In general, information leakage exists on most web Servers installed by default, one of which is PHP. PHP is now a popular server-side html embedded language ?). 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.

1. [root@CentOS66 ~]# vi /etc/php.ini

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

1. expose_php =Off

Before that, the web server header looks like this:

1. [root@centos66 ~]# curl -I http://www.ehowstuff.com/

1. HTTP/1.1200 OK
2. Server: nginx
3. Content-Type: text/html; charset=UTF-8
4. Vary:Accept-Encoding
5. X-Powered-By: PHP/5.3.3
6. X-Pingback: http://www.ehowstuff.com/xmlrpc.php
7. Date:Wed,11Feb201514:10:43 GMT
8. X-Page-Speed:1.9.32.2-4321
9. 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:

1. HTTP/1.1200 OK
2. Server: nginx
3. Content-Type: text/html; charset=UTF-8
4. Vary:Accept-Encoding
5. X-Powered-By: PHP/5.3.3
6. X-Pingback: http://www.ehowstuff.com/xmlrpc.php
7. Date:Wed,11Feb201514:10:43 GMT
8. X-Page-Speed:1.9.32.2-4321
9. 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 the Apache version display. If you are using an Nginx server, add it to the http segment.server_tokens off;Configuration. Please remember to restart related services for the above modifications.
