Let us look into 6 Crucial Tips To Secure Your Website From Hackers In PHP:
1. Cross-Site Request Forgery (CSRF)
One of the most common issues with PHP securities is Cross-Site Request Forgery (CSRF). It is the scenario where complete access to your entire app rests in the hands of hackers. They get access to your website by transferring the infected coding to the website. The purpose of hacking a website is to perform malicious operations & CSRF eases this process. Your website becomes prone to data theft, functional modifications, and other attacks as the hackers can quickly transfer infected code to your website. To protect your website from these malicious attacks, you must start using the GET requests in your URL and ensure the non-GET requests only get generated from your client-side code.
2. Cross-Site Scripting (XSS)
One of the most dangerous external attacks is Cross-Site Scripting (XSS). It refers to the attack where a hacker injects malicious code or script into your website. Such attacks are highly infectious as they can affect the insider cores of any well-targeted app. If you are dealing with a website that accepts and submits user data, there is a higher probability of an XSS attack. Further, to protect yourself from XSS attacks, you must start using HTML special chars & ENT_QUOTES in your application codes.
3. Prevent SQL Injection Attacks
The main component for any website is its database & the hackers may try to go through the same with an SQL injection. The hackers make use of specific URL parameters to perform SQL injection attacks. The attackers can alter fields & queries of your application and get control over your database. Further, they might attempt to delete your entire database through these attacks. The best way to secure your application from such attacks is to run parameterized queries. Such queries replace the arguments before running the SQL query and act as an effective tool to prevent SQL injection attacks.
4. Session Hijacking
As its name suggests, Session Hijacking is an attack where the attacker intends to steal your session ID so that he may gain access to your account. The attacker may try to validate your session through this session ID by sending a request to the server, where a $_SESSION array validates its uptime. The user has no clue about these malicious attempts; being carried out by the hackers. You can prevent your application from session hijacking by binding your sessions to your actual IP address. By doing this, you can invalidate your sessions whenever an unknown violation occurs and get notified if someone tries to browse through your session ID.
5. Always use SSL Certificate
Using SSL certificates on your application provides additional security & ensures end-to-end secured data transmissions over the internet. You can use Hypertext Transfer Protocol Secure (HTTPS), a globally recognized standard protocol to transfer data between the servers without hindrance. The SSL certificates act as a shield for your certificate and make it impossible for hackers to interfere with the servers. Popular browsers such as Google Chrome, Safari, Firefox, Opera, and others recommend using an SSL certificate as it allows secured data transfer.
6. Hide files from the Browser
The prominent framework files like controllers, models, the configuration file (.yaml), and other files rest in a specific directory structure in the micro PHP frameworks. These files never get processed by the browsers; still, users store them in the browser. Such files build a security breach for the application. To prevent such attacks, you can store your files in a public folder rather than keeping them in the root directory.
Although PHP-powered websites provide ample benefits, you must ensure that your data is secure and safe from different attacks or breaches. You can follow the tips above to protect your PHP website from hackers. Also, Secure websites help you gain the trust of your clients.
