Web Application Firewall (WAF) package for Laravel

Originally published at https://github.com/akaunting

This package intends to protect your Laravel app from different type of attacks such as XSS, SQLi, RFI, LFI, User Agent, and a lot more. It will also block repeated attacks and send notification via email and/or slack when attack is detected. Furthermore, it will log failed logins and block the IP after a number of attempts.

Note: Some middleware classes (i.e. Xss) are empty as the Base class that they extend does all of the job, dynamically. In short, they all works ;)

Getting Started

1. Install

Run the following command:

composer require akaunting/firewall

2. Register (for Laravel < 5.5)

Register the service provider in config/app.php

Akaunting\Firewall\Provider::class,

3. Publish

Publish configuration, language, and migrations

php artisan vendor:publish --tag=firewall

4. Database

Create db tables

php artisan migrate

5. Configure

You can change the firewall settings of your app from config/firewall.php file

Usage

Middlewares are already defined so should just add them to routes. The firewall.all middleware applies all the middlewares available in the all_middleware array of config file.

Route::group(['middleware' => 'firewall.all'], function () {
    Route::get('/', 'HomeController@index');
});

You can apply each middleware per route. For example, you can allow only whitelisted IPs to access admin:

Route::group(['middleware' => 'firewall.whitelist'], function () {
    Route::get('/admin', 'AdminController@index');
});

Or you can get notified when anyone NOT in whitelist access admin, by adding it to the inspections config:

Route::group(['middleware' => 'firewall.url'], function () {
    Route::get('/admin', 'AdminController@index');
});

Available middlewares applicable to routes:

firewall.all
firewall.agent

firewall.geo

firewall.ip

firewall.lfi

firewall.php

firewall.referrer

firewall.rfi

firewall.session

firewall.sqli

firewall.swear

firewall.url

firewall.whitelist

firewall.xss

You may also define routes for each middleware in config/firewall.php and apply that middleware or firewall.all at the top of all routes.

Notifications

Firewall will send a notification as soon as an attack has been detected. Emails entered in notifications.email.to config must be valid Laravel users in order to send notifications. Check out the Notifications documentation of Laravel for further information.
