Set Up Policy Guardrails (CI/CD)

You can use the Tenable Cloud Security CLI to scan code in your CI/CD pipeline and fail the builds if Tenable Cloud Security finds severe vulnerabilities in the code. After installing Tenable Cloud Security CLI on the build machine, you must add the necessary instructions to the pipeline script to run the tool against the files present in the repository.

Following are some examples:

Azure DevOps (on MAC)

Add the following commands to the YAML file:

Copy 
trigger:
-master 

pool:
vmImage: ‘macOS-latest’

steps

task: 
 inputs:
   script: |
     brew install terraform
     brew install accurics
     export ARM_SUBSCRIPTION_ID= subscription id
     export ARM_TENANT_ID= tenant id
     export ARM_CLIENT_ID= client id
     export ARM_CLIENT_SECRET= client secret
     accurics init
     accurics plan

See Integration with Azure DevOps Pipeline.

AWS Code Pipeline (On Linux)

Add the following commands to the buildspec.YAML file:

Copy 
version: 0.2

phases:
 install:
   commands:
curl -s -qL -o terraform_install.zip https://releases.hashicorp.com/terraform/0.13.5/terraform_0.13.5_linux_amd64.zip
unzip terraform_install.zip -d /usr/bin/

chmod +x /usr/bin/terraform

   finally:
terraform --version

 build:
   commands:
export ARM_SUBSCRIPTION_ID=subscription ID
export ARM_TENANT_ID=tenant ID
export ARM_CLIENT_ID=client ID
export ARM_CLIENT_SECRET=client secret
./accurics init
./accurics plan

Bamboo (on Linux)

Add the following commands in the Script body of a Script Configuration in a Bamboo Task.

Copy 
cp /home/user/AccuricsCLI/* ./
export ARM_SUBSCRIPTION_ID=<SUBSCRIPTION ID>
export ARM_TENANT_ID=<TENANT ID>
export ARM_CLIENT_ID=<CLIENT ID>
export ARM_CLIENT_SECRET=<CLIENT SECRET>
./accurics init
./accurics plan
if [ $? -eq 0 ]; then exit 0; else exit 1; fi
Note: Make sure to replace the Azure credential placeholder values with valid Azure credentials (required for Terraform):
  • SUBSCRIPTION ID
  • TENANT ID
  • CLIENT ID
  • CLIENT SECRET

GitLab

The following example shows a GitLab pipeline.

Copy 
variables:
  awsAccessKey: 5XXXXXXXXXYYYYYYYYY5
  awsSecretAccessKey: 5XXXXXXXXXXXXXXXXXXYYYYYYYYYYYYYYYYY5
  tcsCLIVersion: latest
  tfVersion: 1.0.11

  GIT_BRANCH: $CI_COMMIT_BRANCH

  script: |
    if [ $do_plan_or_scan == plan ]; then
        export AWS_ACCESS_KEY=$awsAccessKey

      echo ~~~~~RUNNING Tenable CS non plan based assessment..
      ./tcs-iac-scanner scan -mode=pipeline -project=$tcsProjectID -appurl=$tcsURL -token=$apiToken
    fi
Note: Add the following command in your pipeline before running the accurics init command to specify the commit branch:
export GIT_BRANCH=${CI_COMMIT_BRANCH}
Caution: If the IaC scan fails with the "panic: runtime error: invalid memory address or nil pointer dereference" error, add the following command to the variables section of the pipeline:
GIT_BRANCH: $CI_COMMIT_BRANCH
