Expose is an Intrusion Detection System for PHP loosely based on the PHPIDS project (and using its ruleset for detecting potential threats).

ALL CREDIT for the rule set for Expose goes to the PHPIDS project. Expose literally uses the same JSON configuration for its execution. I am not claiming any kind of ownership or authorship of these rules. Please see the PHPIDS github README for names of those who have contributed.

NOTE: An IDS system should not be relied upon for sole protection in your environment! It should only be used in the first level of threat identification. Please read up on "Defense in Depth" for more information on a layered security approach.

Quick Install

  1. Install Composer:

    curl -s https://getcomposer.org/installer | php
  2. Require Expose as a dependency using Composer:

    php composer.phar require enygma/expose
  3. Install Expose:

    php composer.phar install

Example Usage

require 'vendor/autoload.php';

$data = array(
    'POST' => array(
        'test' => 'foo',
        'bar' => array(
            'baz' => 'quux',
            'testing' => '<script>test</script>'

$filters = new \Expose\FilterCollection();

//instantiate a PSR-3 compatible logger
$logger = new \Expose\Log\Mongo();

$manager = new \Expose\Manager($filters, $logger);

echo 'impact: '.$manager->getImpact()."\n"; // should return 8

// get all matching filter reports
$reports = $manager->getReports();

// export out the report in the given format ("text" is default)
echo $manager->export();
echo "\n\n";
