How Does Xray Scan Your Builds?
There are three players in this process:
- Your CI Build
Currently supported for Jenkins, Azure DevOps, Bamboo, TeamCity and JFrog CLI.
The CI build sends a request to Xray, through JFrog Artifactory, for the build to be scanned. If the scan detects a vulnerability, the CI build can take appropriate action.
- JFrog Artifactory
JFrog Artifactory serves as a mediator between the CI server and Xray. It does nothing more than pass information between one and the other.
- JFrog Xray
Upon request, if Xray has defined watches with Actions to fail a build job, it will scan the build, and respond with a message that the build job should fail if a vulnerability is detected in the build artifact or one of its dependencies.
The diagram below illustrates how the process is implemented.
- The CI build runs.
Assuming the build is successful, the CI build publishes the build-info to Artifactory.
- New build artifacts and dependencies are automatically indexed by Xray.
- The CI build passes a request to Artifactory to scan the build.
- Artifactory passes a request to scan the build through Xray's scanBuild REST API endpoint.
Xray scans the build according to a defined Watch with a Fail Build Job Action action.
Note title Multiple watches or no watches?
You may define multiple Watches with a Fail Build Job Action, each with its own criteria (i.e. Artifact Filters and/or Issue Filters) that should trigger an alert. All of these Watches are applied each time a build is scanned.
If Xray receives a scanBuild request, and there are no Watches defined with a Fail Build Job Action, Xray will always respond with an indication to fail the build job, even if no vulnerabilities are found in the build artifacts or their dependencies.
- If a build artifact or dependency meets the conditions (filters) defined in the Watch, Xray triggers an alert and...
Xray responds to the scanBuild request indicating that the build job should fail.
Tip title All Alerts in one response
The response includes the details of all Alerts generated by all Watches that include a Fail Build Job Action.
- Artifactory passes on the response back to Jenkins.
- Jenkins fails the build job.
Setting Up Xray CI Integration
For Xray to scan builds upon request by a CI server, you need to configure a Watch with the right filters that specify which artifacts and vulnerabilities should trigger an alert, and set a Fail Build Job Action for that Watch.
Configuring your CI Server
Xray CI/CD integration is supported for Jenkins CI, TeamCity, and Bamboo.
To configure a build job to request a scan, with the Jenkins Artifactory Plug-in (v2.9.0 and above), you need to create a
scanConfig instance and and pass it to the
xrayScan method in the Jenkins Pipeline.
To scan build artifacts for vulnerabilities, with the Bamboo Artifactory Plug-in, you need to add the Artifactory Xray Scan task to your plan. The task should follow a previous task which publishes the build-info to Artifactory.
To scan build artifacts for vulnerabilities using JFrog CLI, you need to use the jfrog rt scan-build command.
While Artifactory does not play an active part in this integration, and there is no explicit configuration needed, Artifactory does play a passive role in passing information between your CI server and JFrog Xray.
This feature is supported in Artifactory from v4.16 and above.
Managing Scanned Builds
Xray's build integration allows you to manage your build jobs and configure them with appropriate actions if build artifacts or dependencies with vulnerabilities are found in your builds. While the default action (in Jenkins) is to simply stop the build, you can actually configure your pipeline to do other things like send email notifications or even run a different build job.
