Tip: How PHP versions are hidden in Linux servers

Typically, most of the default settings for installing Web server Software are information leaks, one of which is PHP. PHP is one of the most popular service-side HTML embedded languages today. And in today's challenging era, there are many hackers who try to discover vulnerabilities on your server. As a result, an article on the Ehowstuff Web site briefly describes how to hide PHP information from Linux servers.

　　

By default, expose_php is on by default, and the "expose_php" parameter is turned off to allow PHP to hide its version information.

[Email protected] ~]# Vi/etc/php.ini

On the php.ini, locate the line containing the expose_php and set the on to OFF:

expose_php = Off

Before changing the settings, the Web server header looks like this:

[Email protected] ~]# curl-i http://www.ehowstuff.com/

http/1.1 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, 14:10:43 GMT x-page-speed:1.9.32.2-4321 cache-control:max-age=0, No-cache

After you change and restart the Web service, PHP does not display the version in the Web Service header:

http/1.1 OK Server:nginx date:wed, one 15:38:14 GMT content-type:text/html; 　　Charset=utf-8 vary:accept-encoding x-pingback:http://www.ehowstuff.com/xmlrpc.php date:wed, 14:10:43 GMT x-page-speed:1.9.32.2-4321 cache-control:max-age=0, No-cache

Although there is a certain information risk, but PHP as one of the powerful language of web development, with open source code, cross-platform strong, fast development, high efficiency, object-oriented, professional focus and many other advantages, so that the PHP development framework also makes the program development simple and effective.
