You can monitor application security for PHP apps running in host-based or container-based environments such as Docker, Kubernetes, AWS ECS, and AWS EKS.

Prerequisites

• The Datadog Agent is installed and configured for your application’s operating system or container, cloud, or virtual environment.
• If your service is running with an Agent with Remote Configuration enabled and a tracing library version that supports it, you can block attackers from the Datadog UI without additional configuration of the Agent or tracing libraries.

Enabling Application & API Protection

Get started

1. Install the latest Datadog PHP library by downloading and running the installer:

   wget https://github.com/DataDog/dd-trace-php/releases/latest/download/datadog-setup.php -O datadog-setup.php
   php datadog-setup.php --php-bin all --enable-appsec
   

   To check that your service’s language and framework versions are supported for Application & API Protection capabilities, see Compatibility.

2. Enable the library in your code by restarting PHP-FPM or Apache. In a containerized environment, if you previously installed the library without enabling Application & API Protection, you can optionally enable it after by setting the following environment variables:

   Update your configuration container for APM by adding the following arguments in your docker run command:

   docker run [...] -e DD_APPSEC_ENABLED=true -e DD_APM_TRACING_ENABLED=false [...]
   

   Add the following environment variable values to your container Dockerfile:

   ENV DD_APPSEC_ENABLED=true
   ENV DD_APM_TRACING_ENABLED=false
   

   Update your configuration yaml file container for APM and add the environment variables:

   spec:
     template:
       spec:
         containers:
           - name: <CONTAINER_NAME>
             image: <CONTAINER_IMAGE>/<TAG>
             env:
               - name: DD_APPSEC_ENABLED
                 value: "true"
               - name: DD_APM_TRACING_ENABLED
                 value: "false"
   

   Update your ECS task definition JSON file, by adding these in the environment section:

   "environment": [
     ...,
     {
       "name": "DD_APPSEC_ENABLED",
       "value": "true"
     },
     {
       "name": "DD_APM_TRACING_ENABLED",
       "value": "false"
     }
   ]
   

   La bibliothèque recueille des données de sécurité à partir de votre application et les envoie à l’Agent, qui les transmet à son tour à Datadog. Les règles de détection prêtes à l’emploi signalent alors les attaques et les problèmes potentiels de configuration, afin que vous puissiez agir en conséquence.

3. Pour tester la détection des menaces Application Security Management, envoyez des patterns d’attaque connus à votre application. Par exemple, exécutez un fichier contenant le script curl suivant afin de déclencher la règle de détection de scanner de sécurité :

   for ((i=1;i<=250;i++)); 
   do
   # Target existing service’s routes
   curl https://your-application-url/existing-route -A dd-test-scanner-log;
   # Target non existing service’s routes
   curl https://your-application-url/non-existing-route -A dd-test-scanner-log;
   done

   Remarque : la plupart des versions récentes prennent en charge la valeur dd-test-scanner-log.

   Quelques minutes après avoir activé votre application et envoyé les patterns d’attaque, des informations sur les menaces s’affichent dans l’Application Trace and Signals Explorer de Datadog.
