Built in security features in Laravel and best practices to make Laravel based web applications more secure.

By Sameer Thakur

Laravel is considered as one of the best PHP based framework because of its builtin features like Authorisation, Object Oriented Libraries, Artisan, MVC support, Security etc. In this blog post we will discuss about the security features Laravel provides and best practices which we can use to make the laravel based applications more secure.

Builtin Security Features in Laravel

  • Authentication
  • CSRF Protection
  • XSS Protection
  • Avoiding SQL Injection

 

Authentication

Laravel provides its own Authentication system which uses Providers and Guides for authentication process. Providers allows the data retrival from Database while Guards defines how users are authenticated for each request user makes.

If you are developer you need not to do any special to activate this feature, you just need to setup laravel on your system and it will work perfectly.

 

CSRF Protection

CSRF stands for Cross Site Request Forgery. This feature is used to avoid any third party malicious requests. To detect and stop any malicious requests, Laravel uses a token in every request it recieves from authenticated users. In case any request which doesn’t have this token it consider it as invalid request.

 

XSS

XSS stands for Cross Site Scripting. XSS attacks are those where hacker uses input fields to add malicious scripts in the web application. So when a new user visit the web application this script will also execute with thier request. To avoid this scenario Laravel XSS protection feature stops the system to process the harmful script and output as html.

 

Avoiding SQL Injection

In Laravel Eloquent ORM uses PDO binding to protect the web application from SQL Injections. It ensures that user request variables are not directly used in SQL queries.

 

Although Laravel provides many security features these features can’t assure 100% security from malicious attacks. Here are some other techniques which you can use to make your web app more secure.

  • HTTPS: Laravel is basically used to devleop custom web application where a lot of sensitive information is exchanged with user and application so if you are making a custom web application in Laravel you should use HTTPS instead on HTTP. It will encrypt the data exchanged between the user and application and prevents from malicious attacks.
  • Prevention from SQL Injection: You should avoid writing raw queries and should use eloquent ORM becuase raw queries makes your web application vunerable for SQL Injection attacks.
  • Prevention from XSS: To prevent your web application from XSS attacks you should use double brace syntax in the blade templates.

These are existing security features laravel provides and some other techniques to make your web application more secure. I hope this post will be helpful for you in understanding laravel security features and enhancing its security.
