README

Catch the policy violations your users generate and store them somewhere

Install

Via Composer

$ composer require zae/csp-reporting

Usage

Configure your csp reports to go to /csp-report.

Laravel

Publish the config file using artisan vendor:publish

#config/csp-report.php

return [
    'persist' => [
        'class' =>  LogCspPersister::class,
        'properties' => [
            'loglevel' => Psr\Log\LogLevel::INFO
        ]
    ],
    'limiter' => [
        'class' => CspCacheLimiter::class,
        'properties' => [
            'key' => 'csp-rate-limiter',
            'maxAttempts' => 1,
            'decay' => 60
        ]
    ],
];

By default the plugin will store the violations in the log, but there is also a BugsnagPersister that will send the violation to bugsnag.

Craft 3

Configure your application to use the Module with the right limiter and persister.

use Zae\ContentSecurityPolicyReporting\Contracts\CspLimiter;
use Zae\ContentSecurityPolicyReporting\Contracts\CspPersistable;
use Zae\ContentSecurityPolicyReporting\Limiters\CspLotteryLimiter;
use Zae\ContentSecurityPolicyReporting\Persisters\BugsnagCspPersister;

return [
    'bootstrap' => [
        'csp-reporting'
    ],
    'components' => [
        'csp-reporting' => [
            'class' => \Zae\ContentSecurityPolicyReporting\Craft\Module::class,
            'components' => [
                CspPersistable::class => static function () {
                    return new BugsnagCspPersister(
                        \Bugsnag\Client::make(getenv('BUGSNAG_API_KEY'))
                    );
                },
                CspLimiter::class => static function () {
                    return new CspLotteryLimiter(5);
                }
            ]
        ],
    ]
]

On high traffic sites the violations might occur often and probably they will all be the same, so the limiter will make sure only a part of the violations will actually be stored.

The properties array will allow you to configurate the handlers.

You can also provide your own classes as long as they implement the right interfaces.
