Exploring Laravel Security Best Practices to Reduce Protection Risks in Apps

Table of Contents

Exploiting a loophole in an application or unprotected platform is not a difficult task today. Security is a primary concern for web applications. A developer must keep the vulnerabilities in mind and all the possible issues that may arise during the process. You need to cover various segments to ensure your app remains protected.

Fortunately, the Laravel framework offers many useful security features, tools, and practices. If you use this framework for development, rest assured that Laravel security tools will deliver the results you intended.

The text here will tell you how to secure Laravel apps and dive into the best practices to implement. 

Key Takeaways

  • Keeping security levels high for Laravel apps
  • Best practices any Laravel development company can follow
  • Useful security features to keep in mind

Built-In Security Laravel Security Tools

Inbuilt Laravel security features allow developers to gain access to multiple safety layers. Although no one can guarantee 100% security, these features secure Laravel applications for users and developers. Let us explore some of these features in detail.

  • Cross-Site Request Forgery or CSRF Protection

By default, Laravel uses Forum Token Method or CSRF token for development. These pre-defined CSRF tokens and filters area come embedded in the source code. 

CSRF protection ensures that the request comes for the application and not any third-party XSS attack. CSRF protection works by returning an HTTP 500 error and denying access if the filter detects any threatening or unauthorized request. 

  • Cookie Protection

Laravel also ensures that the cookies are safe, provided developers created them using an application or encryption key. Depending on the version of Laravel, for version 5 or above, developers have to add the key to the app.php file in the config folder. In lower versions, use application.php in the config directory.

  • Hashing Password

According to Laravel Hashing documentation, Laravel comes equipped with native hash mechanisms based on Bcrypt and Argon2. Argon2 has two further variants, Argon2i and Argon2id.

Developers can use Laravel’s own LoginController and RegisterController classes. Developers enable user password saving, authentication, and registration using Bcrypt as default. 

  • Encryptions

Another useful Laravel security tool is the encryption feature that allows Laravel website development services to leverage the OpenSSL library. The library provides AES-128 and AES-256 safety encryptions, and Laravel signs all the encrypted values using the Message Authentication Code (MAC) to ensure no unauthorized party may modify encrypted data.

  • Sessions Management

Laravel’s API allows developers access to an array of drivers and databases. The most prominent are config/session.php file, array, Redis, Memcached, cookies, and APC.

Laravel applies a file driver by default, a versatile option fitting many web applications. Memcached and Redis boost session performance, and professional web development companies in Houston recommend them for a wide production environment.  

Best Practices to Overcome Security Issues with Laravel Apps

Laravel completes much of the security work upfront, especially if a developer decides to run default options and does not focus much on customization. 

Since we have an idea about the features available, let us look at some of the best practices and steps to secure Laravel apps.

  • Updating Laravel Installation

The first practice that every developer should follow is to keep the firmware updated. It includes all the third-party libraries and the default framework installed via composer. New security threats always arise, and updated software helps reduce Laravel vulnerabilities with new patches.

  • Cookie Protection and Password Hashing

Laravel automatically generates an encryption key for users whenever they access the config directory. However, a secure practice is to change that key into a difficult and random password of about 25-35 characters. The simple step doubles the protection and minimizes the possibility of unauthorized breaches. 

As mentioned above, Laravel has a native hash mechanism with a general rule of “slow hashes = best hashes.” Since Bcrypt and Argon2 are the best mechanisms, do not use weak password hashing functions such as MD5 and SHA1 to keep security high at all levels.

  • Reducing Laravel Vulnerabilities from CSRF

CSRF happens when an attacker tricks any user into taking action on a web application already authenticated for them. The goal is to make the users send actions and enable attackers to gain access instead of the authenticated user. 

For instance, a common practice by attackers is an email or messaging platform that enables image that supports image embedding containing hidden form data made on JavaScript. Users do not even realize what happened, and the attacker gains access. 

Enabling CSRF protection immediately follows with an HTTP 500 error when it detects unauthorized or outside entry.

  • Protection against XSS (Cross Site Scripting)

XSS is a vulnerability that allows attackers to run a script in the context of a targeted application. It occurs when input from a user is on an HTML page without any validation or encoding. The move causes session hijacking, phishing, and other attacks 

The best method of prevention is to use Laravel Blade templates: {{{ }}} introduced back in Laravel 4 and is still considered a standard for XSS protection.

  • Protection against SQL Injection

SQL injection is a vulnerability that allows attackers to run SQL commands and statements in the application leading to the loss or theft of data. Preparing statements in advance is the best method to avoid SQL injection, while Laravel also offers Object Relational Mapper (ORM), termed Eloquent, for the purpose.

Reducing Laravel Vulnerabilities – More Recommendations

Besides the methods mentioned above, Laravel developers can utilize recommended approaches to keep the application and development process under strict scrutiny. Some of the more common Laravel security best practices are as follows:

  • Validate everything, whether the server, any request (POST or GET), or data that comes through any other route. Laravel validation rules and instructions guide a developer to create a safety feature. 
  • Following Laravel’s built-in security tools for encryption is the best way to keep the applications safe from unauthorized access.
  • Destroy HTTP sessions after a significant state change to an app. 
  • Keep SSL/TLS sessions up to date
  • Limit requests to Prevent DDoS attacks
  • Set a Content Security Policy for everyone to follow
  • Constant security monitoring and tracking

Conclusion

In conclusion, developers can follow numerous best practices for reducing Laravel vulnerabilities to secure their applications. They need to keep their firmware up to date with authentications, data filtering, and routine reviews, and following these best practices improves the security of the application data. As a professional web development company in Houston, our experts recommend these steps to ensure the safety of the application from unknown access or attacks.
