Security system for Yii2

Yii2 Guard

Security system for Yii2. The extension is able to detect and repel Overdrive attack, XSS attack, LFI / RFI / RCE attack, PHP / SQL injection attacks, and block by over rate limit. As well as block the user by IP and network (possible to add blocking client manually).

This module is an integral part of the Butterfly.СMS content management system, but can also be used as an standalone extension.

Routing

Use the Module::dashboardNavItems() method of the module to generate a navigation items list for NavBar, like this:

<?php
    echo Nav::widget([
    'options' => ['class' => 'navbar-nav navbar-right'],
        'label' => 'Modules',
        'items' => [
            Yii::$app->getModule('guard')->dashboardNavItems(),
            ...
        ]
    ]);
?>
