Sysdig Secure Container Image Scanner

Sysdig Secure Jenkins Plugin

Jenkins Plugins Jenkins Plugin installs

Sysdig Secure is a container security platform that brings together Docker image scanning and run-time protection to identify vulnerabilities, block threats, enforce compliance, and audit activity across your microservices. The Sysdig Secure Jenkins plugin can be used in a Pipeline job, or added as a build step to a Freestyle job to automate the process of running an image analysis, evaluating custom policies against images, and performing security scans.

Getting Started

Pre-requisites

Requires a valid Sysdig Secure API token

Jenkins workers need to have access to the image storage, either to the local storage where the image was created or to the registry where it is stored.

Installation

The Sysdig Secure plugin is published as a Jenkins plugin and is available for installation on any Jenkins server using the Plugin Manager in the web UI through the Manage Jenkins > Manage Plugins view, available to administrators of a Jenkins environment.

See https://www.jenkins.io/doc/book/managing/plugins/

Global configuration

Required Config

To configure the Sysdig Secure plugin:

  1. Complete these steps after installing the plugin.

  2. From the main Jenkins menu, select Manage Jenkins.

  3. Click the Configure System link.

    Confgure Jenkins

  4. Scroll down to the Sysdig Secure Plugin section.

  5. In the Sysdig Secure API Credentials drop-down, click Add button to create a new credential containing the Sysdig Secure API Token that you can find in Sysdig Secure -> Settings -> User Profile. You only need to fill the password field and keep the user blank. Oncre created, select the new credential in the Sysdig Secure API Credentials drop-down.

Sysdig Token Configuration

  1. Enter the Sysdig Secure API endpoint in the Sysdig Secure Engine URL field. For On-Prem installations, this is the URL where your Secure API is exposed. For SaaS service:

    • Default region US East (North Virginia): https://secure.sysdig.com
    • US West (Oregon): https://us2.app.sysdig.com
    • European Union: https://eu1.app.sysdig.com

    Check SaaS Regions and IP Ranges for a complete list of regions

Sysdig Plugin Configuration

  1. If you are connecting to an On-Prem instance using an invalid TLS certificate, then you need to either configure Jenkins to trust the certificate, or uncheck the Verify SSL checkbox.

  2. Click Save.

Usage

Build Step

In order to use the plugin you need to include the Sysdig Image Scanning build step either on your freestyle projects or your pipelines. It is possible to globally enforce jobs configured with legacy build step to execute the redesigned engine by selecting the option force usage of new scanning engine in the global configuration.

Example 1: Integrate the Sysdig Secure Plugin with a Freestyle Project

  1. Using the Jenkins Docker plugin for this example, you could start by building the image and writing the image name to the sysdig_secure_images file

  2. Open the Add build step drop-down menu, and select Sysdig Image Scanning. This creates a new build step labeled Sysdig Image Scanning Build Options.

    Add step in Freestyle Job

  3. Configure the available options, and click Save.

Example 2: Executing the Sysdig plugin inside a pipeline

The following is a simplified example executing the Sysdig plugin as a stage inside a pipeline

stages {
    stage('Checkout') {
        steps {
            checkout scm
        }
    }
    stage('Build Image') {
        steps {
            sh "docker build -f Dockerfile -t ${params.DOCKER_REPOSITORY} ."
        }
    }
    stage('Scanning Image') {
        steps {
            sysdigImageScan engineCredentialsId: 'sysdig-secure-api-credentials', imageName: "${params.DOCKER_REPOSITORY}"
        }
    }
}

The table below describes each of the configuration options.

Execution options

Option Parameter Description Default
Image name ImageName The name of the image to scan sysdig_secure_images
Fail build on policy check STOP result bailOnFail If the Sysdig Secure policy evaluate returns a fail (STOP), then the Jenkins job should be failed. If this is not selected then a failed policy evaluation will allow the build to continue. true
Fail build on critical plugin error bailOnPluginFail If selected, and the Sysdig Secure Plugin experiences a critical error, the build will be failed. This is typically used to ensure that a fault with Sysdig Secure (eg. service not available) does not permit a failing image to be promoted to production. true
Identifiers of policies to apply policiesToApply List of policies to apply to the image in addition to those marked as always apply in the sysdig ui

The following is an example of executing the Sysdig Secure plugin as a Jenkinsfile step, modifying the default parameters

sysdigImageScan bailOnFail: false, bailOnPluginFail: false, engineCredentialsId: 'sysdig-secure-api-credentials', engineURL: 'https://secure.sysdig.com', engineVerify: false, imageName: 'ruby', policiesToApply: 'foo', scannerBinaryPath: '/bin/sysdig-cli-scanner'

Plugin outputs

Once the scanning and evaluation is complete, you will have the following build artifacts and reports in the workspace

sysdig_secure_gates.json Scanning results for the Sysdig policy evaluation.

sysdig_secure_security.json Detected vulnerability data

sysdig_secure_raw-vulns_report-.json Raw vulnerability data

Additionally, the plugin offers you an HTML formatted table output that you can directly display from the interface (Sysdig Secure Report (FAIL) in the image above)

Local development and installation

Use docker to build the sysdig-secure.hpi file:

docker run -it --rm --name maven-jenkins-builder -v "$(pwd)":/usr/src/app -w /usr/src/app maven:3.6.3-jdk-8 mvn package

You can then install the plugin via the Jenkins UI, or by copying it into $JENKINS_HOME/plugins.
