Build Process Description:

The build process for OpenProject is assumed to be automated using a CI/CD system like GitHub Actions, triggered by code changes pushed to the Git repository.

Build Process Steps:

Source Code Checkout: The CI/CD system checks out the latest source code from the Git repository.
Dependency Resolution: Dependencies are resolved and downloaded (e.g., Ruby gems, Node.js modules).
Compilation/Build: The application code is compiled and built into executable artifacts.
Unit Tests: Automated unit tests are executed to verify code functionality.
SAST Scanning: Static Application Security Testing (SAST) tools are used to scan the source code for potential security vulnerabilities.
Dependency Scanning: Dependency scanning tools are used to identify known vulnerabilities in third-party dependencies.
Container Image Build: Container images (e.g., Docker images) are built for the Web Application, API Application, and Background Workers.
DAST Scanning (Optional): Dynamic Application Security Testing (DAST) tools may be used to scan a deployed instance of the application for vulnerabilities (this step might be part of a separate deployment pipeline).
Build Artifacts: Build artifacts, including container images and packages, are generated.
Push Images: Container images are pushed to a container registry.

Build Process Security Controls:

security control: Automated build process to ensure consistency and repeatability.
security control: Source code repository access control to protect code integrity.
security control: SAST scanning to identify and remediate code-level vulnerabilities early in the development cycle.
security control: Dependency scanning to identify and update vulnerable dependencies.
security control: Container image scanning for vulnerabilities before deployment.
security control: Secure storage of build artifacts and container images in the container registry.
security control: Code signing and image signing to ensure artifact integrity and authenticity.
security control: Access control to the CI/CD system and build pipelines.
