Overview

Datadog Code Analysis allows you to identify and resolve code quality issues and security vulnerabilities before deploying to production, ensuring safe and clean code throughout the software development lifecycle.

Code Analysis offers a comprehensive suite of tools, including Static Analysis and Software Composition Analysis, to improve overall software delivery.

• Static Analysis (SAST) scans your repositories for quality and security issues in first-party code, and suggests fixes to prevent these issues from impacting production.
• Software Composition Analysis (SCA) scans your codebase for imported open source libraries, helping you manage your dependencies and secure your applications from external threats.

By using datadog-ci, you can integrate analyses from other providers into your development workflow, allowing you to send Static Analysis and SCA results directly to Datadog. You can access the latest scan results for each repository on the Repositories page to effectively monitor and enhance code health across all branches.

Set up Code Analysis

You can configure Code Analysis to run scans on code directly in Datadog or on code running in your CI pipelines. To get started, navigate to Software Delivery > Code Analysis > Repositories and click + Add a Repository.

With Datadog-hosted scans, your code is scanned within Datadog’s infrastructure as opposed to within your CI pipeline. Datadog reads your code, runs the static analyzer to perform Static Analysis and/or Software Composition Analysis, and uploads the results.

Using Datadog-hosted scans eliminates the need for you to configure a CI pipeline so you can use Code Analysis.

Enable Code Analysis on your GitHub repositories for each GitHub Account you’ve added by setting up the GitHub integration.

You can either enable Software Composition Analysis (SCA) to scan for vulnerabilities, licensing issues, and supply chain risks in your open source libraries for all repositories, or you can enable SCA for individual repositories in the Repositories side panel.

Select from the following types of scans you want to run in your repository.

• Static Analysis: Examine your code for poor practices and vulnerabilities.
• Software Composition Analysis: Check your third-party libraries for vulnerabilities.

Select a source code management (SCM) provider such as GitHub or another provider.

GitHub

If you are using a GitHub repository, you can set up the GitHub integration and connect your repository to enable Static Analysis and Software Composition Analysis scans.

Comments in GitHub pull requests are enabled by default. Click Connect Repositories on the Code Analysis Setup page and hover over the Missing flag on the PR Permissions column to see which permissions you need to update for your account.

To disable this feature, navigate to the Code Analysis Settings page and click the toggle in the GitHub Comments column.

Other providers

For other providers, you can run the Datadog CLI directly in your CI pipeline platform. For more information, see Generic CI Providers for Static Analysis and Generic CI Providers for Software Composition Analysis.

You must run an analysis of your repository on the default branch for results to start appearing on the Repositories page.

Run Code Analysis in your CI provider

To upload results to Datadog, ensure you have a Datadog API key and application key.

Specify a name for the service or library in the dd_service field such as shopist.

GitHub Action

You can configure a GitHub Action to run Static Analysis and Software Composition Analysis scans as part of your CI workflows.

Create a .github/workflows/datadog-static-analysis.yml file in your repository with the following content:

on: [push]

name: Datadog Static Analysis

jobs:
  static-analysis:
    runs-on: ubuntu-latest
    name: Datadog Static Analyzer
    steps:
    - name: Checkout
      uses: actions/checkout@v3
    - name: Check code meets quality and security standards
      id: datadog-static-analysis
      uses: DataDog/datadog-static-analyzer-github-action@v1
      with:
        dd_api_key: ${{ secrets.DD_API_KEY }}
        dd_app_key: ${{ secrets.DD_APP_KEY }}
        dd_service: shopist
        dd_env: ci
        dd_site: datadoghq.com
        cpu_count: 2

Then, create a .github/workflows/datadog-sca.yml file in your repository with the following content:

on: [push]

name: Datadog Software Composition Analysis

jobs:
  software-composition-analysis:
    runs-on: ubuntu-latest
    name: Datadog SBOM Generation and Upload
    steps:
    - name: Checkout
      uses: actions/checkout@v3
    - name: Check imported libraries are secure and compliant
      id: datadog-software-composition-analysis
      uses: DataDog/datadog-sca-github-action@main
      with:
        dd_api_key: ${{ secrets.DD_API_KEY }}
        dd_app_key: ${{ secrets.DD_APP_KEY }}
        dd_service: shopist
        dd_env: ci
        dd_site: datadoghq.com

Customizable script

You can upload a SARIF report with Static Analysis results or an SBOM report with Software Composition Analysis results to Datadog using the datadog-ci NPM package.

Static Analysis

To upload Static Analysis reports to Datadog, you must install Unzip and Node.js version 14 or later.

Add the following content to your CI pipeline configuration:

# Set the Datadog site to send information to
export DD_SITE="datadoghq.com"

# Install dependencies
npm install -g @datadog/datadog-ci 
                
# Download the latest Datadog static analyzer:
# https://github.com/DataDog/datadog-static-analyzer/releases
DATADOG_STATIC_ANALYZER_URL=https://github.com/DataDog/datadog-static-analyzer/releases/latest/download/datadog-static-analyzer-x86_64-unknown-linux-gnu.zip

curl -L $DATADOG_STATIC_ANALYZER_URL > /tmp/ddog-static-analyzer.zip
unzip /tmp/ddog-static-analyzer.zip -d /tmp
mv /tmp/datadog-static-analyzer /usr/local/datadog-static-analyzer
                
# Run Static Analysis
/usr/local/datadog-static-analyzer -i . -o /tmp/report.sarif -f sarif
                
# Upload results
datadog-ci sarif upload /tmp/report.sarif --service "shopist" --env "ci"

Software Composition Analysis

To upload Software Composition Analysis results to Datadog, you must install Trivy and Node.js version 14 or later.

Add the following content to your CI pipeline configuration:

# Set the Datadog site to send information to
export DD_SITE="datadoghq.com"
                        
# Install dependencies
npm install -g @datadog/datadog-ci

# Download the latest Datadog OSV Scanner:

# Upload results
datadog-ci sbom upload --service "shopist" --env "ci" /tmp/sbom.json

Once you’ve configured these scripts, run an analysis of your repository on the default branch. Then, results will start appearing on the Repositories page.

Run Static Analysis in an IDE

Install the Datadog IDE plugins to run Static Analysis scans locally and see results directly in your code editor. You can detect and fix problems such as maintainability issues, bugs, or security vulnerabilities in your code before you commit your changes.

To start running Static Analysis scans in your IDE, see the respective documentation for your code editor of choice.

Enable Code Analysis comments in GitHub pull requests

You can integrate Code Analysis with GitHub pull requests to automatically flag code violations and enhance code quality in the review process.

When configured, Code Analysis directly comments on the PR, indicating violations with details such as the name, ID, severity, and suggested fixes, which you can directly apply from the GitHub UI.

After adding the appropriate configuration files to your repository, create a GitHub App in Datadog (a new app or an update to an existing one). Ensure it has the proper read and write access to pull requests.

Once you’ve configured your app, navigate to the Code Analysis Settings page and click the toggle in the GitHub Comments column for each repository.

For more information, see GitHub Pull Requests.

Search and manage repositories

Click on a repository on the Repositories page to access a more detailed view where you can customize the search query by branch (with the default branch appearing first) and by commit (starting with the latest).

You can use the following out-of-the-box facets to create a search query for identifying and resolving poor coding practices in the Code Quality tab or security risks in the Code Vulnerabilities tab.

Facet Name	Description
Result Status	Filters results based on the completion status of the analysis.
Rule ID	Specific rules that triggered the findings.
Tool Name	Determines which tools contributed to the analysis.
CWE (Common Weakness Enumeration)	Filters findings by recognized vulnerability categories.
Has Fixes	Filters issues for which suggested fixes are available.
Result Message	Contains concise descriptions or messages associated with the findings.
Rule Description	Contains the rationale behind each rule.
Source File	Contains the files where issues were detected.
Tool Version	Filters results by the version of the tools used.

You can access suggested fixes directly from the results to improve code quality practices and address security vulnerabilities.

You can use the following out-of-the-box facets to create a search query for identifying and addressing security risks in third-party libraries in the Library Vulnerabilities tab or reviewing your library inventory in the Library Catalog tab.

Facet Name	Description
Dependency Name	Identifies the libraries by name.
Dependency Version	Filters by specific versions of libraries.
Language	Sorts libraries by the programming language.
Score	Sorts the risk or quality score of the dependencies.
Severity	Filters vulnerabilities based on their severity rating.
Platform	Distinguishes libraries by the platform they are intended for.

You can access vulnerability reports and locate the source files where the vulnerability was discovered in your projects, along with information about the file’s code owners.

Explore results in the Service Catalog

Investigate code violations associated with your services and code violations identified from Static Analysis to troubleshoot slowdowns and failures. Navigate to Service Management > Services > Service Catalog and click on the Delivery view to analyze the pre-production status of your services.

Click on a service to access information about CI pipelines from Pipeline Visibility, in addition to security vulnerabilities and code quality issues from Code Analysis on the Delivery tab of the side panel.

Linking services to code violations and libraries

Datadog associates code violations or libraries with relevant services by using the following mechanisms:

1. Identifying the code location associated with a service using the Service Catalog.
2. Detecting usage patterns of files within additional Datadog products.
3. Searching for the service name in the file path or repository.

If one method succeeds, no further mapping attempts are made. Each mapping method is detailed below.

Identifying the code location in the Service Catalog

The schema version v3 and later of the Service Catalog allows you to add the mapping of your code location for your service. The codeLocations section specifies the location of the repository containing the code and its associated paths.

The paths attribute is a list of globs that should match paths in the repository.

apiVersion: v3
kind: service
metadata:
  name: my-service
datadog:
  codeLocations:
    - repositoryURL: https://github.com/myorganization/myrepo.git
      paths:
        - path/to/service/code/**

Detecting file usage patterns

Datadog detects file usage in additional products such as Error Tracking and associate files with the runtime service. For example, if a service called foo has a log entry or a stack trace containing a file with a path /modules/foo/bar.py, it associates files /modules/foo/bar.py to service foo.

Detecting service name in paths and repository names

Datadog detects service names in paths and repository names, and associates the file with the service if a match is found.

For a repository match, if there is a service called myservice and the repository URL is https://github.com/myorganization/myservice.git, then, it associates myservice to all files in the repository.

If no repository match is found, Datadog attempts to find a match in the path of the file. If there is a service named myservice, and the path is /path/to/myservice/foo.py, the file is associated with myservice because the service name is part of the path. If two services are present in the path, the service name the closest to the filename is selected.

Linking teams to code violations and libraries

Datadog automatically associates the team attached to a service when a code violation or library issue is detected. For example, if the file domains/ecommerce/apps/myservice/foo.py is associated with myservice, then the team myservice will be associated to any violation detected in this file.

If no services or teams are found, Datadog uses the CODEOWNERS file in your repository. The CODEOWNERS file determines which team owns a file in your Git provider.

Note: You must accurately map your Git provider teams to your Datadog teams for this feature to function properly.
