Exploring Laravel Security Best Practices to Reduce Protection Risks in Apps

Laravel Security

Last Updated on January 20, 2023 by Team Experts

Today, it does not take much effort to exploit a security weakness on an unprotected platform or software application. For this reason, web application security is of paramount importance. A developer must keep the vulnerabilities in mind and all the probable concerns that may occur throughout the procedure. The security of your app depends on your attention to several details.

Happily, Laravel has a number of helpful security features, tools, and practices built right in. Laravel’s security mechanisms will ensure that your code is safe if you utilize this framework. This article delves into the best practices for securing Laravel applications and provides guidance on how to do this.

Protection Already Implemented Security Tools for Laravel

As a developer, you have access to many different levels of protection thanks to Laravel’s built-in security capabilities. There is no way to ensure complete safety for users and developers of Laravel apps, but these measures should help. Let’s take a closer look at a few of these characteristics.

  • Security Against Cross-Site Request Forgery (CSRF)

Laravel’s default development setup makes use of the Forum Token Method or a CSRF token. Included in the source code are CSRF tokens and filters that have already been created.

The application, and not a malicious third party attempting an XSS attack, will get the request thanks to CSRF safeguards. If a CSRF filter identifies an unsafe or unwelcome request, it will respond with an HTTP 500 error and block the user’s access to the resource in question.

  • Protecting Cookies

As long as the cookies were generated by an application or encryption key, Laravel will also guarantee their security. For Laravel 5 and later, the key should be added to the app.php file in the config folder. Earlier releases should utilize the application.php file found in the config folder.

  • Encryptions

Laravel’s encryption functionality, which enables Laravel development services to utilize the OpenSSL library, is another helpful security tool. Laravel signs all encrypted information using the Message Authentication Code (MAC) to prevent tampering, and the library supports the more secure AES-128 and AES-256 ciphers.

  • Password Hashing

The Laravel Hashing documentation states that Laravel ships with Bcrypt and Argon2 based native hash algorithms. In addition to the original Argon2, there are two further forms, Argon2i and Argon2id.

To facilitate authentication, Laravel provides its own LoginController and RegisterController classes for developers. By default, Bcrypt is used by developers for user password storage, authentication, and registration.

  • Administration of Meetings

Developers may connect too many drivers and databases using Laravel’s application programming interface. The most well-known ones include the config/session.php file, array, Redis, Memcached, cookies, and APC.

Laravel’s default implementation of a file driver is a flexible choice that can be used with a wide variety of websites. Web designers agree that using Memcached and Redis in a large-scale production environment improves session speed.

The Most Effective Methods for Securing Laravel Applications

Laravel handles a lot of the heavy lifting in terms of security up front, particularly if the developer chooses to use the default configuration and not do much in the way of customization.

Since we have an understanding of the features available, let us look at some of the Laravel security best practices and measures to protect Laravel projects.

  • Changing to the Latest Laravel Release

The first practice that any developer should follow is to keep the firmware updated. All dependencies, including composer’s default framework and external libraries, are bundled together. Always-evolving security concerns need constant software updates, which repair Laravel’s known flaws.

  • Safeguarding Cookies and Hashing Passwords

Any time a user navigates to the config directory, Laravel creates a unique encryption key for that user. Instead of using that key, it’s safer to replace it with a complex, randomly generated password of at least 25 characters. Taking this one easy action effectively doubles security and significantly reduces the likelihood of a compromise.

As was previously established, Laravel’s built-in hash mechanism operates on the principle “slow hashes = better hashes.” Password hashing methods like MD5 and SHA1 are insecure and should be avoided in favor of Bcrypt and Argon2.

  • Safeguarding Laravel Against Cross-Site Request Forgery

Any user may fall victim to CSRF if they are duped into performing an activity inside an authorized web application while the attacker is still posing as the authenticated user. The purpose is to trick users into sending activities so that attackers may get access in place of the authorized user.

An example of an attack technique is the use of a message or email platform that allows images to be embedded, with the form data concealed in an image using JavaScript. Without the victim’s knowledge, the attacker is able to get access. When CSRF protection is activated and illegal access is discovered, an instant HTTP 500 error is generated.

  • Safety from XSS Exploitation (Cross Site Scripting)

XSS is a vulnerability that enables attackers to execute a script in the context of a targeted application. It happens when a user enters data on an HTML page without the page being validated or the data being encoded. This change opens the door to phishing and other forms of assault. Laravel Blade templates, first introduced in Laravel 4, remain the gold standard for cross-site scripting (XSS) avoidance.

  • Defense against SQL Injection

Data loss or theft may occur as a result of SQL injection vulnerabilities because they enable attackers to execute SQL commands and statements inside the program. The easiest way to prevent SQL injection is to prepare statements ahead of time, and Laravel provides an Object Relational Mapper (ORM) called Eloquent for just that reason.

Further Suggestions for Securing Laravel

Not only may Laravel developers use the above-mentioned techniques, but they can also use suggested measures to maintain rigorous monitoring of the application and development process. What follows are examples of some of the most widespread recommended procedures for ensuring the safety of your Laravel application:

It’s important to double-check everything before using it, including the server, the request (GET or POST), and the data it contains. A developer may easily implement a security measure with the help of Laravel’s validation rules and tutorials.

  • The easiest approach to prevent unwanted access to the apps is to use the encryption technologies that come standard with Laravel.
  • Destroy HTTP sessions following a large state change to an app.
  • Secure communications must always use the most recent versions of SSL/TLS.
  • Limit requests to Prevent DDoS attacks
  • Make everyone abide by a strict Content Security Policy.
  • Tracking and monitoring systems that run constantly for security


In conclusion, there are several guidelines that developers may follow to make their apps more resistant to Laravel’s security flaws. The safety of the application’s data may be enhanced by adhering to best practices such keeping the firmware up to date with authentications, data filtering, and frequent reviews.
