(). {% /alert %} {% /callout %} {% alert level="info" %} You can enable App and API Protection for .NET services with the following setup options: 1. If your .NET service already has APM tracing set up and running, then skip to service configuration. 1. If your .NET service doesn't have APM tracing set up, you can easily enable App and API Protection with Datadog's [Automatic Installation](https://docs.datadoghq.com/tracing/trace_collection/automatic_instrumentation/single-step-apm/kubernetes.md). 1. Otherwise, continue reading the manual setup instructions below. {% /alert %} ## Overview{% #overview %} App and API Protection leverages the [Datadog .NET library](https://github.com/DataDog/dd-trace-dotnet/) to monitor and secure your .NET service. The library integrates seamlessly with your existing application without requiring code changes. For detailed compatibility information, including supported .NET versions, frameworks, and deployment environments, see [.NET Compatibility Requirements](https://docs.datadoghq.com/security/application_security/setup/dotnet/compatibility.md). This guide explains how to set up App and API Protection (AAP) for .NET applications. The setup involves: 1. Installing the Datadog Agent. 1. Enabling App and API Protection monitoring. 1. Running your .NET application with the Datadog Agent. 1. Verifying the setup. ## Prerequisites{% #prerequisites %} - Kubernetes cluster - .NET application containerized with Docker - kubectl configured to access your cluster - Helm (recommended for Agent installation) - Your Datadog API key - Datadog .NET tracing library (see [version requirements](https://docs.datadoghq.com/security/application_security/setup/dotnet/compatibility.md)) ## 1. Installing the Datadog Agent Install the Datadog Agent by following the [setup instructions for Kubernetes](https://docs.datadoghq.com/agent.md?tab=cloud_and_container). ## 2. Enabling App and API Protection monitoring If your .NET service already has APM tracing set up and running, you can automatically enable App and API Protection through Remote ConfigurationIf not, enable App and API Protection with the manual configuration instructions.navigation-menu{background:#f8f9fa;border:1px solid #e9ecef;border-radius:8px;padding:20px;margin:20px 0}.nav-container h3{margin-top:0;margin-bottom:15px;color:#333;font-size:1.1em}.nav-list{list-style:none;padding:0;margin:0}.nav-list li{margin-bottom:8px}.nav-list a{color:#06c;text-decoration:none;font-weight:500}.nav-list a:hover{text-decoration:underline;color:#049} ### Automatically enabling App and API Protection through Remote Configuration{% #automatically-enabling-app-and-api-protection-through-remote-configuration %} You can enable services with remote configuration on your [services dashboard](https://app.datadoghq.com/security/configuration/asm/setup?services=recommended). Check the box for the service you want to enable App and API Protection for under Activate on your APM services. ### Manually enabling App and API Protection monitoring{% #manually-enabling-app-and-api-protection-monitoring %} Ensure your Dockerfile includes the Datadog .NET library: ```dockerfile # Download and install Datadog .NET Tracer ENV DD_TRACE_VERSION=3.20.0 RUN curl -sSL https://github.com/DataDog/dd-trace-dotnet/releases/download/v${DD_TRACE_VERSION}/datadog-dotnet-apm-${DD_TRACE_VERSION}.linux-x64.tar.gz \ | tar -xz -C /opt/datadog # Set environment variables for Datadog automatic instrumentation ENV CORECLR_ENABLE_PROFILING=1 \ CORECLR_PROFILER="{846F5F1C-F9AE-4B07-969E-05C26BC060D8}" \ CORECLR_PROFILER_PATH=/opt/datadog/Datadog.Trace.ClrProfiler.Native.so \ DD_DOTNET_TRACER_HOME=/opt/datadog \ ``` {% collapsible-section %} #### APM Tracing Enabled Update your Kubernetes deployment to include the required environment variables: ```yaml apiVersion: apps/v1 kind: Deployment metadata: name: your-dotnet-app spec: template: spec: containers: - name: your-dotnet-app image: your-dotnet-app-image env: - name: DD_APPSEC_ENABLED value: "true" - name: DD_SERVICE value: "" - name: DD_ENV value: "" ``` {% /collapsible-section %} {% collapsible-section %} #### APM Tracing Disabled To disable APM tracing while keeping App and API Protection enabled, you must set the APM tracing variable to false. Update your Kubernetes deployment to include the required environment variables: ```yaml apiVersion: apps/v1 kind: Deployment metadata: name: your-dotnet-app spec: template: spec: containers: - name: your-dotnet-app image: your-dotnet-app-image env: - name: DD_APPSEC_ENABLED value: "true" - name: DD_APM_TRACING_ENABLED value: "false" - name: DD_SERVICE value: "" - name: DD_ENV value: "" ``` {% /collapsible-section %} ## 3. Run your application Apply your updated deployment: ```bash kubectl apply -f your-deployment.yaml ``` ## 4. Verify setup To verify that App and API Protection is working correctly: 1. Send some traffic to your application 1. Check the [Application Signals Explorer](https://app.datadoghq.com/security/appsec) in Datadog 1. Look for security signals and vulnerabilities ## Troubleshooting{% #troubleshooting %} If you encounter issues while setting up App and API Protection for your .NET application, see the [.NET App and API Protection troubleshooting guide](https://docs.datadoghq.com/security/application_security/setup/dotnet/troubleshooting.md). ## Further Reading{% #further-reading %} - [How App and API Protection Works](https://docs.datadoghq.com/security/application_security/how-it-works.md) - [OOTB App and API Protection Rules](https://docs.datadoghq.com/security/default_rules.md?category=cat-application-security) - [Troubleshooting App and API Protection](https://docs.datadoghq.com/security/application_security/troubleshooting.md)
