You can monitor application security for Java apps running in Docker, Kubernetes, Amazon ECS, and AWS Fargate.

In general, setting up Application Security Management (ASM) involves:

1. Identifying services that are vulnerable or are under attack, which would most benefit from ASM. Find them on the Security tab of your Service Catalog.
2. Updating to the latest Datadog library (the most recent APM tracing library).
3. Enabling the library to collect the application security data from the services and send it to Datadog.
4. Triggering security signals in your application and seeing how Datadog displays the resulting information.

Prerequisites

• The Datadog Agent is installed and configured for your application’s operating system or container, cloud, or virtual environment.
• Datadog APM is configured for your application or service, and traces are being received by Datadog.
• 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 code security vulnerability detection

If your service runs a tracing library version that supports code security vulnerability detection, enable the capability by setting the DD_IAST_ENABLED=true environment variable and restarting your service.

To detect code security vulnerabilities for your service:

1. Update your Datadog Agent to at least version 7.41.1.

2. Update your tracing library to at least the minimum version needed to turn on code security vulnerability detection. For details, see ASM capabilities support.

3. Add the DD_IAST_ENABLED=true environment variable to your application configuration.

   From the command line:

   java -javaagent:/path/to/dd-java-agent.jar -Ddd.iast.enabled=true -Ddd.service=<MY SERVICE> -Ddd.env=<MY_ENV> -jar path/to/app.jar
   

   Or one of the following methods, depending on where your application runs:

   Note: Read-only file systems are not supported. The application must have access to a writable /tmp directory.

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

   docker run [...] -e DD_IAST_ENABLED=true [...]
   

   Add the following environment variable value to your container Dockerfile:

   DD_IAST_ENABLED=true
   

   Update your deployment configuration file for APM and add the IAST environment variable:

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

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

   "environment": [
     ...,
     {
       "name": "DD_IAST_ENABLED",
       "value": "true"
     }
   ]
   

4. Restart your service.

5. To see Software Composition Analysis for code security vulnerabilities in action, browse your service and the code security vulnerabilities appear in the Vulnerability Explorer. The SOURCE column shows the Code value.
