SonarCloud vulnerability scanning
We use SonarCloud as a static analysis tool to analyse the code in the
sourcegraph/sourcegraph repository for security vulnerabilities.
For Security engineers
Changing the SonarCloud configuration
You can login to the SonarCloud website using your GitHub credentials, and should then be able to view the SonarCloud configuration.
SonarCloud is configured with a quality gate. This means that only code that SonarCloud determines has a ‘Security Grade’ of A is considered passing.
sourcegraph/sourcegraph has a branch merge protection defined: any code
which fails the quality gate will not be allowed into the
main branch. A GitHub
admin will be required to change this.
Changing the GitHub/SonarCloud integration
You will need to either be or have access to a GitHub Admin to change this.
The SonarCloud GitHub app runs a check against all branches/pull requests, as well as
against the main branch. It currently only scans the Sourcegraph product via
There isn’t much other configuration to set up or change for the GitHub app.
For Sourcegraph engineers
Any SonarCloud issues should be visible to you via the output of the SonarCloud Code Analysis GitHub check. If you’re not clear on how to resolve an issue raised by SonarCloud, please reach out to the Security team in #security.
If the offending commit has to be landed as part of resolving an incident, find an admin for the repository (for whom branch protection rules will not apply) to merge the code in for you.
