The Issue of PHP Security

Tight security needs to be applied in every area of web hosting. Hackers can come at you from many different angles, starting with the scripts used to create your web pages.

Over the years, PHP has established a strong presence on the internet. Its capability as one of the first server-side scripting languages has been embraced by most web hosting platforms and PHP continues to grow. At the same time this popular language has come under attack of many online hackers. Even though PHP was designed to be a secure script, users must be totally aware of the vulnerability that comes along with it. The sole purpose of this next section is to provide you with factual details of the many security related issues that the PHP language is susceptible to.

There are a number of things that lead to corruption and the violation of PHP scripts. These issues have the power to ultimately damage the server your website is running on and the operating system as well. Keep in mind that this advice is meant to reduce the risk of security issues that relate to the PHP language. While you may find these methods of resolution helpful, they should not be used as the only means of protecting your content.

PHP was designed to be web language that makes scripting web pages an easy task. Novice programmers will find an abundance of tutorials that teach the aspects of PHP. With a little research, users have the ability to create web applications in no time. The bad part of this is that many of these tutorials and training articles fail to stress the security measures that need to be applied to PHP. They will give the basics which more often than not lead users to create web pages that are full of database errors and several other security defections.

Since PHP thrives on a being an open-source, easy to use language, programmers have made things worse by adding features that initiate security problems on many levels. One of the worst additions of all is the “register_globals” feature. This will automatically execute a PHP script from a CGI variable that is passed in POST or GET. This makes it a bit easier for developers to access these values but also grants permission to experienced hackers. A hacker will then have the power to adjust the value for variables in that PHP script. The dynamics of PHP does not call for variables to be initialized in order to be used, a feature that many applications rely on. When the register_globals command comes into play, it makes PHP much easier to control by intruders.

For the most part, the register_globals command has been disabled in the updated versions of PHP. On the other hand, many of today’s frequently used web applications still depend on it. A few web hosts have enabled the feature by the popular demand of their customers.

Many efforts have been made to improve the quality of PHP scripts, indicating that security issues do exist. A few of the original PHP developers have taken the liberty of blaming the free-roaming users while refusing to accept the flaws that came along with the script and its evolution.
