Accurics GitHub Action

Description

The Accurics GitHub action runs an Accurics scan against the IaC (Infrastructure-as-Code) files found within the applied repository. This action can be used to fail a pipeline build when violations or errors are found. The scan results can be viewed in the pipeline results or in the Accurics Console itself at https://cloud.tenable.com/cns depending on url configured. See examples below.

Setup

    steps:
      - name: Accurics
        uses: tenable/accurics-action@v2.0.2
        id: accurics
        with:
          app-id: ${{ secrets.ACCURICS_APP_ID }}
          env-id: ${{ secrets.ACCURICS_ENV_ID }}

Create GitHub secrets to store the Environment ID and Application Token. Open your Repository Settings->Secrets tab->New Secret. Create two secrets called "ACCURICS_APP_ID" and "ACCURICS_ENV_ID" filled with the "app" and "env" values copied from the config file downloaded from the Accurics UI environment tab.
Add "app-id" and "env-id" parameters referencing the respective GitHub secrets. See the examples below for more info.
Add a "repo" parameter that contains the remote repo location.
If not using the latest Terraform version, specify the "terraform-version" parameter within the build step.
If variables are used, add them in the "plan-args" parameter, along with any other command line parameters that should be passed when running "terraform plan" (see the example below)

Cost

The Accurics GitHub action runs as a Linux container, which means it accumulates minutes while running at the same rate Linux containers are charged by GitHub. Please refer to the GitHub action billing page for more detailed information.

Examples

Example 1:

This example configures an Accurics Scan with a custom Terraform version and variables. It will also fail the build on any violations or errors found.

    steps:
      # Required to checkout the files in the current repository
      - name: Checkout
        uses: actions/checkout@v2
      - name: Accurics
        uses: tenable/accurics-action@v2.0.2
        id: accurics
        env: 
          # Required by Terraform
          AWS_ACCESS_KEY_ID: ${{ secrets.AWS_ACCESS_KEY_ID }}
          AWS_SECRET_ACCESS_KEY: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
          REPO_URL: ${{ github.repositoryUrl }}
          GIT_BRANCH:  ${{ github.ref_name }}
          GIT_COMMIT:  ${{ github.sha }}
        with:
          # Required by Accurics
          app-id: ${{ secrets.ACCURICS_APP_ID }}
          env-id: ${{ secrets.ACCURICS_ENV_ID }}
          # Optional args
          terraform-version: 0.14.7
          plan-args: '-var myvar1=val1 -var myvar2=val2'
          url: "https://cloud.tenable.com/cns"

Example 2:

This example configures an Accurics Scan using the latest Terraform version, custom variables, and instructs the action not to fail when any violations are found. This is helpful when first introducing the action into a new codebase and working through a large number of violations. Once the number of violations is manageable, the option can be set back to true (or removed).

    steps:
      - name: Checkout
        uses: actions/checkout@v2
      - name: Accurics
        uses: tenable/accurics-action@v2.0.2
        id: accurics
        env:
          # Required by Terraform
          AWS_ACCESS_KEY_ID: ${{ secrets.AWS_ACCESS_KEY_ID }}
          AWS_SECRET_ACCESS_KEY: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
          REPO_URL: ${{ github.repositoryUrl }}
          GIT_BRANCH:  ${{ github.ref_name }}
          GIT_COMMIT:  ${{ github.sha }}
        with:
          # Required by Accurics
          app-id: ${{ secrets.ACCURICS_APP_ID }}
          env-id: ${{ secrets.ACCURICS_ENV_ID }}
          repo: "https://bitbucket.org/myrepo/reponame.git"
          # Optional args
          plan-args: '-var myvar1=val1 -var myvar2=val2'
          fail-on-violations: false
          url: "https://cloud.tenable.com/cns"
          scan-mode: "plan"
          pipeline: true

Example 3:

This is the same configuration as before, but it now includes an extra build step to display the output scan status, also sets scan mode to terrascan scan.

    steps:
      - name: Checkout
        uses: actions/checkout@v2
      - name: Accurics
        uses: tenable/accurics-action@v2.0.2
        id: accurics
        env:

          fail-on-violations: false
          url: "https://cloud.tenable.com/cns"
          scan-mode: "scan"
          pipeline: true

            echo "Violation Count            : ${{ steps.accurics.outputs.num-violations }}";
            echo "Resource Count             : ${{ steps.accurics.outputs.num-resources }}";

            echo "Inherited Resources        : ${{ steps.accurics.outputs.inherited }}";
            echo ""
            echo "High-Severity Violations   : ${{ steps.accurics.outputs.high }}";
            echo "Medium-Severity Violations : ${{ steps.accurics.outputs.medium }}";
            echo "Low-Severity Violations    : ${{ steps.accurics.outputs.low }}";
            echo ""
            echo "Drift                      : ${{ steps.accurics.outputs.drift }}";
            echo "IaC Drift                  : ${{ steps.accurics.outputs.iacdrift }}";
            echo "Cloud Drift                : ${{ steps.accurics.outputs.clouddrift }}";
            echo ""
          '
