Security/Application Security Pipeline

Purpose
This document provides guidance on how to implement security into the CI/CD pipeline, leveraging both GitLab's integrated tools and custom tools provided and developed by the Security Team.

In an effort to improve application security testing, our goal has been to “shift left” to remove more vulnerabilities earlier. The idea is to empower developers to find and fix vulnerabilities earlier in the software development lifecycle, when changes are less costly and more timely.

With security embedded into the development workflow, developers can get feedback on the security of their code as they are working, they can remediate in real time, and free up the security team’s time to focus on monitoring issues, assessing risk, and solving vulnerabilities that can’t be fixed by the developer. By continuously testing even small, incremental code changes, an avalanche of work is avoided at the end of the SDLC.

Note: The Security Team strongly recommends including security scanning tools into either migrated or new repository pipelines. These features have to be triggered both for new Merge Requests and for Continuous Development/Delivery.

Use Cases

 * Allows security flaws to be fixed early, when less expensive, removes context-switching, and minimizes risk by preventing vulnerabilities from reaching production.
 * Reduces security and compliance risks.

Templates Provided by the Security Team
The Security Team strongly suggest to use the relevant templates located at this GitLab repository. In order to include these templates, please see the documentation.

Custom Templates
Even though the Security Team strongly advises against the use of custom templates, there is the possibility to implement your own custom ones.

GitLab Default Templates
For all of the remaining Languages/Frameworks not supported by the Security Team, there is the possibility to use the GitLab default one. It features automatic language detection which works even for mixed-language projects. If any supported language is detected in the project source code it automatically runs the appropriate SAST analyzers.

Even though the results may not be the greatest, it could still provide some value. Here is the list of GitLab supported languages.

How to configure GitLab default SAST templates
To enable and configure SAST with default settings:
 * 1) On the top bar, select Menu > Projects and find your project.
 * 2) On the left sidebar, select Security & Compliance > Configuration.
 * 3) In the SAST section, select.
 * 4) Review the draft MR that enables SAST with the default recommended settings in the   file.
 * 5) Merge the MR to enable SAST. You should see SAST jobs run in that MR’s pipeline.

Results
Security automation is far from perfect. Even though our goal is to have straight-forward scan results and fully automated remediations, unfortunately that is not always possible. Results may be polluted by False Positives, and remediations may appear unclear. When these scenarios occur, please get in touch with the Security Team to work on possible solutions.

Note: Repository owners are implicitly accepting the risk of the findings. It is your own responsibility to fix issues or to accept potential threats. Please contact the Security Team to get help on how to address the issues.

How to check results
Usually security tools emit a report that is in the form of a JSON result file.

The JSON report file can be downloaded from the CI pipelines page, or the pipelines tab on merge requests by setting  to. For more information see the documentation.

E.g.:

For phpcs-security-tool add this to the  file:
