Laravel Surveillance

Laravel Surveillance is a package to put malicious users, IP addresses and anonymous browser fingerprints under surveillance, write surveillance logs and block malicious ones from accessing the app.

Please read the IMPORTANT INFORMATION below before using this package

This package collects and processes various attributes that may be Personal Identifiable Information and this should therefore be disclosed and screened before adopting this package. This packages author does not take responsibility for any compliance issues users may face. Please consult legal expertise to use responsibly.

This package provides:

1. A middleware to be used on routes.

2. A command line interface to enable/disable surveillance and block/unblock access.

3. A fluent API to programmatically enable/disable surveillance, block/unblock access and log the requests at runtime.

4. By default the package used MySQL database as storage but the package can be extended to use virtually any storage technology.

NOTE: This package does not provide a client side library for browser fingerprinting. FingerprintJS Open Source is a good library to use for client side browser fingerprinting.

Important Announcement !

Introducing Laravel Surveillance UI : A package which provides Graphical UI for Laravel Surveillance and integrates within your existing application.

Minimum Requirements

1. Laravel 6.0

2. PHP 7.2

Installation

1. Install the package via composer:

composer require neelkanthk/laravel-surveillance

2.1. Publish the migration files:

php artisan vendor:publish --provider="Neelkanth\Laravel\Surveillance\Providers\SurveillanceServiceProvider" --tag="migrations"

2.2. Publish language files:

php artisan vendor:publish --provider="Neelkanth\Laravel\Surveillance\Providers\SurveillanceServiceProvider" --tag="lang"

3. Run the migrations

php artisan migrate

4. After migrations have been run two tables will be created in the database namely surveillance_managers and surveillance_logs

5. You can publish the config file with:

php artisan vendor:publish --provider="Neelkanth\Laravel\Surveillance\Providers\SurveillanceServiceProvider" --tag="config"

This is the contents of the file that will be published at config/surveillance.php:

return [

    /*
     * The name of the header to be used for browser fingerprint
     */
    "fingerprint-header-key" => "fingerprint",

    /*
     *  This class is responsible enabling, disabling, blocking and unblocking.
     *  To override the default functionality extend the below class and provide its name here.
     */
    "manager-repository" => 'Neelkanth\Laravel\Surveillance\Implementations\SurveillanceManagerRepository',

    /*
     *  This class is responsible for logging the surveillance enabled requests
     *  To override the default functionality extend the below class and provide its name here.
     */
    "log-repository" => 'Neelkanth\Laravel\Surveillance\Implementations\SurveillanceLogRepository',

    /*
     *  The types which are allowed currently.
     *  DO NOT MODIFY THESE
     */
    "allowed-types" => ["userid", "ip", "fingerprint"]
];

CLI Usage

Enable surveillance for an IP Address

php artisan surveillance:enable ip 192.1.2.4

Disable surveillance for an IP Address

php artisan surveillance:disable ip 192.1.2.4

Enable surveillance for a User ID

php artisan surveillance:enable userid 1234

Disable surveillance for a User ID

php artisan surveillance:disable userid 1234

Enable surveillance for Browser Fingerprint

php artisan surveillance:enable fingerprint hjP0tLyIUy7SXaSY6gyb

Disable surveillance for Browser Fingerprint

php artisan surveillance:disable fingerprint hjP0tLyIUy7SXaSY6gyb

Block an IP Address

php artisan surveillance:block ip 192.1.2.4

UnBlock an IP Address

php artisan surveillance:unblock ip 192.1.2.4

Block a User ID

php artisan surveillance:block userid 1234

UnBlock a User ID

php artisan surveillance:unblock userid 1234

Block a Browser Fingerprint

php artisan surveillance:block fingerprint hjP0tLyIUy7SXaSY6gyb

UnBlock a Browser Fingerprint

php artisan surveillance:unblock fingerprint hjP0tLyIUy7SXaSY6gyb

Remove a Surveillance record from Database

php artisan surveillance:remove ip 192.5.4.3

Middleware Usage

You can use the 'surveillance' middleware on any route or route group just like any other middleware.

NOTE: The middleware looks for the browser fingerprint in the header name as set in the fingerprint-header-key inside config/surveillance.php

Route::middleware(["surveillance"])->get('/', function () {
    
});

Programmatic Usage

Enable Surveillance

use Neelkanth\Laravel\Surveillance\Services\Surveillance;
Surveillance::manager()->type("ip")->value("192.5.4.1")->enableSurveillance();

Block Access

use Neelkanth\Laravel\Surveillance\Services\Surveillance;
Surveillance::manager()->type("userid")->value(2121)->blockAccess();

Logging a Request (Works when surveillance in enabled on User ID, IP Address or Browser Fingerprint)

use Neelkanth\Laravel\Surveillance\Services\Surveillance;
Surveillance::logger()->writeLog();

Allowed Types

Currently only userid, ip and fingerprint types are allowed.

Customizing and Overriding the defaults

To override the default surveillance management functionality

Step 1: Extend the SurveillanceManagerRepository Class and override all of its methods

//Example repository to use MongoDB instead of MySQL
namespace App;

use Neelkanth\Laravel\Surveillance\Implementations\SurveillanceManagerRepository;
use Illuminate\Support\Carbon;

class SurveillanceManagerMongoDbRepository extends SurveillanceManagerRepository
{
    public function enableSurveillance()
    {
        $surveillance = $this->getRecord();
        if (is_null($surveillance)) {
            $surveillance["type"] = $this->getType();
            $surveillance["value"] = $this->getValue();
        }
        $surveillance["surveillance_enabled"] = 1;
        $surveillance["surveillance_enabled_at"] = Carbon::now()->toDateTimeString();
        $collection = (new \MongoDB\Client)->surveillance->manager;
        $insertOneResult = $collection->insertOne($surveillance);
        return $insertOneResult;
    }
}

Step 2: Provide the custom class in the config/surveillance.php file's manager-repository key

/*
 *  This class is responsible enabling, disabling, blocking and unblocking.
 *  To override the default functionality extend the below class and provide its name here.
 */
"manager-repository" => 'App\SurveillanceManagerMongoDbRepository',

To override the default logging funtionality

Step 1: Extend the SurveillanceLogRepository Class and override all of its methods

//Example repository to write Logs in MongoDB instead of MySQL
namespace App;

use Neelkanth\Laravel\Surveillance\Implementations\SurveillanceLogRepository;

class SurveillanceLogMongoDbRepository extends SurveillanceLogRepository
{
    public function writeLog($dataToLog = null)
    {
        if (!is_null($dataToLog)) {
            $this->setLogToWrite($dataToLog);
        }
        $log = $this->getLogToWrite();
        if (!empty($log) && is_array($log)) {
            $collection = (new \MongoDB\Client)->surveillance->logs;
            $insertOneResult = $collection->insertOne($log);
        }
    }
}

Step 2: Provide the custom class in the config/surveillance.php file's log-repository key

/*
 *  This class is responsible for logging the surveillance enabled requests
 *  To override the default functionality extend the below class and provide its name here.
*/
"log-repository" => 'App\SurveillanceLogMongoDbRepository',
