Setting up the CI/CD pipeline

Use Jenkins or GitLab CI/CD as your CI/CD tool. These are popular open source tools that can automate the process of building, testing, and deploying your applications. Here are the stages where these tools can help:

• Source code management: Git is the most commonly used open source tool. Platforms such as GitHub and GitLab provide added features such as pull requests, issues, and CI/CD integrations.
• Static Application Security Testing (SAST): Use tools such as Brakeman (Ruby on Rails), Bandit (Python), or SonarQube to detect vulnerabilities in your source code.
• Dynamic Application Security Testing (DAST): Tools such as OWASP ZAP or Arachni can identify vulnerabilities at runtime by scanning your running application.
• Container security: If you’re using Docker, tools such as Clair, Anchore, or Trivy can scan your containers for known vulnerabilities.
• Dependency scanning: Check for vulnerabilities in your project’s dependencies...
