Easy learning curve and developer-friendly nature, necessities such as the primary reason why PHP is a favorite one of many developers. But, like every other software or programming language, while some of the features make developing a website very easy by using PHP, others may lead developers to formulate applications with security loopholes.   It is possible to build up robust and secure web applications as soon as you identify and know some of the most basic types of security holes that can ruin your PHP web development venture.

However, in this post, we will discuss probably the most common mistakes developers often manufactured in PHP web design that afterward results in security blunders.

1. Not so properly validated input error –   This is one of the most common security blunders developers often commit in PHP Web Application Development. It is not in any respect safe to accept the person’s input without verifying or validating them. Not so validated user input could possibly be the biggest cause of a security breach of one’s website or web application.   Avoid using JavaScript for several types of input as it could often be manipulated through attackers. It is very crucial for you to be as strict and prohibitive while validating any user input and be sure which you don’t allow invalid user inputs whatsoever.

2. Access Control Vulnerabilities –   This sort of security blunder typically takes place as soon as your website or application has certain restricted sections or pages that need users to have certain rights to gain access to those pages or information.   To avoid such issues or security blunders, make sure you make necessary security checks on each of the restricted pages of your respective website or web application so that you can identify the authenticity with the end-user. Also, it is possible to track the IP in the users to validate their identity to gain access to specific pages.

3. XSS or Cross Scripting issues –   Cross-Site Scripting or XSS are few things but security attacks in which malicious or notorious users include JavaScript commands inside the data executed by various other users. To get rid of such a form of security vulnerabilities, make sure you become more attentive and careful while displaying contents or information executed or submitted by other users.

4. Not so properly protected Session IDs –   Exploiting session-id is one of the biggest security issues in PHP web content management. Session tracking & management in PHP language utilize unique session-id of each and every user, in case your id is known to a few other users then who use can certainly explore various critical user information.   Always want to use Secure Socket Layer (SSL) certificates for the website if it deals with critical and sensitive user details. It will help you minimize the risk of vulnerabilities in connection with the session id.

5. Unfiltered characters that can cause SQL injection attacks –   This is one of the very well-known security attacks that comes about when your site doesn’t verify or check any in the data and also doesn’t even filter the characters used in the SQL string. This leads to inappropriate behavior and outcomes from SQL queries used inside the application.   The appropriate way of design & develop web applications could help you develop better, reliable, and secure PHP web applications. So, if you’re planning to jump into PHP website development, make sure you are going through these security blunders to produce secure and effective applications.
