Prisma Cloud Scan

Prisma Cloud Scan Action

IMPORTANT: Please see SUPPORT.md for the official support policy for the contents of this repository.

This GitHub Action will scan container images for vulnerabilities and compliance issues using Prisma Cloud by Palo Alto Networks. With it, you can receive immediate feedback about image vulnerabilities and compliance violations both in GitHub and in the Prisma Cloud Console as well as block builds that do not meet your compliance requirements, such as high or critical vulnerabilities.

This action is a wrapper around twistcli which connects to the specified Prisma Cloud Console for vulnerability and compliance policy and metadata.

Usage

Example of container image scanning

on: [ push, workflow_dispatch ]

env:
  IMAGE_NAME: ${{ github.repository }}:${{ github.sha }}

jobs:
  build-and-scan:
    name: Build and scan image
    runs-on: ubuntu-latest

    steps:
      - name: Check out the repository
        uses: actions/checkout@v2

      - name: Build the image
        run: docker build -t $IMAGE_NAME .

      - name: Prisma Cloud image scan
        id: scan
        uses: PaloAltoNetworks/prisma-cloud-scan@v1.5
        with:
          pcc_console_url: ${{ secrets.PCC_CONSOLE_URL }}
          pcc_user: ${{ secrets.PCC_USER }}
          pcc_pass: ${{ secrets.PCC_PASS }}
          image_name: ${{ env.IMAGE_NAME }}

      # (Optional) for compatibility with GitHub's code scanning alerts
      - name: Upload SARIF file
        if: ${{ always() }} # necessary if using failure thresholds in the image scan
        uses: github/codeql-action/upload-sarif@v2
        with:
          sarif_file: ${{ steps.scan.outputs.sarif_file }}

Properties

Environment variables

Variable	Description	Required?	Default
`DOCKER_ADDRESS`	Address of the Docker daemon (e.g. tcp://localhost:2375)	No
`DOCKER_HOST`	Address of the Docker daemon (e.g. tcp://localhost:2375). `DOCKER_ADDRESS` takes priority.	No

Inputs

Input	Description	Required?	Default
`pcc_console_url`	URL of your Prisma Cloud Compute Console	Yes
`pcc_user`	Username of a user with the CI user role	Yes
`pcc_pass`	Password of a user with the CI user role	Yes
`image_name`	Name (or ID) of the image to be scanned	Yes
`project`	Tenant project context for the command	No
`results_file`	File to which scan results are written in JSON	No	`pcc_scan_results.json`
`sarif_file`	File to which scan results are written in SARIF	No	`pcc_scan_results.sarif.json`
`docker_address`	Address of the Docker daemon (e.g. tcp://localhost:2375)	No
`docker_tlscacert`	Path to the Docker CA certificate	No
`docker_tlscert`	Path to the Docker client certificate	No
`docker_tlskey`	Path to the Docker client private key	No
`twistcli_debug`	Activate the debug flag for prisma cli (by default deactivated)	No
`twistcli_publish`	Publish the results to Prisma Cloud. Default is true.	No

Outputs

Output	Description
`results_file`	File to which scan results are written in JSON
`sarif_file`	File to which scan results are written in SARIF

Control alerting and fail thresholds

You can set the level for alerting and failing builds in the Prisma Cloud UI. For example, setting the alert threshold to Medium will not alert for Low severity vulnerabilities.

Results output

The table of discovered vulnerabilities and compliance violations shows up in the GitHub workflow log and in the Prisma Cloud Console in the Monitor section. If you upload the outputted SARIF file to GitHub, you will also populate the code scanning alerts section in your repository. While the code-scan-to-image-scan mapping isn't perfect, it does provide all available information of each vulnerability and compliance issue. The alerts will automatically close once the issues are fixed and the workflow is ran again.
