DevSecOps Pipeline: CI/CD Security Best Practices Quiz Quiz

Enhance your understanding of DevSecOps pipeline security with this quiz focused on essential CI/CD security best practices, risk management, and secure automation techniques. Ideal for professionals seeking to strengthen their knowledge of secure software delivery processes and threat mitigation in automated pipelines.

1. Source Code Scanning Responsibility

   Within a DevSecOps CI/CD pipeline, who is primarily responsible for ensuring that source code is scanned for vulnerabilities before deployment?

   1. End-users involved in acceptance testing
   2. A single automated build agent
   3. The entire development team, including security engineers
   4. Only the operations staff

   Explanation: The responsibility for scanning source code in a DevSecOps pipeline is shared between the development team and security engineers, embodying the shift-left mentality where security is integrated early and continuously. It is not solely up to operations staff, as they typically focus on deployment and infrastructure. A single automated build agent can perform scans but cannot ensure comprehensive oversight or accountability. End-users do not handle code scanning, as this is a technical responsibility of the development and security teams.

2. Least Privilege Principle

   Why is implementing the principle of least privilege in CI/CD pipeline service accounts a critical security best practice?

   1. It reduces the potential impact if an account is compromised
   2. It makes the pipeline faster by running more processes in parallel
   3. It allows developers to bypass authentication more easily
   4. It is only necessary when using cloud infrastructure

   Explanation: Applying the principle of least privilege restricts accounts to only the permissions they need, limiting damage if those credentials are leaked or abused. Faster pipeline execution is unrelated, so the first option is not correct. This best practice is important for all environments, not just cloud. Allowing developers to bypass authentication undermines security and is not a benefit of least privilege.

3. Secrets Management Example

   A team stores API keys in environment variables managed by a secure vault and injects them during pipeline runs. Which CI/CD security best practice does this scenario represent?

   1. Manual password distribution
   2. Hardcoding secrets in source code
   3. Automated secrets management
   4. Using version control for credential storage

   Explanation: Managing secrets with a vault and automated injection into the pipeline reflects automated secrets management, a key security practice to protect sensitive data. Hardcoding secrets is insecure and strongly discouraged. Storing credentials directly in version control exposes them to unnecessary risk. Manual password distribution is inefficient and less secure than automated solutions.

4. Supply Chain Threat Defense

   What is the primary reason for verifying the integrity and authenticity of third-party dependencies in a CI/CD pipeline?

   1. To comply with user interface design guidelines
   2. To automate rollback procedures
   3. To ensure maximum pipeline speed
   4. To detect and prevent supply chain attacks

   Explanation: Validating third-party dependencies helps prevent supply chain attacks by ensuring that external code has not been tampered with. User interface design guidelines are unrelated to dependency management. Pipeline speed, while important, is not the focus here. Automating rollback is useful, but it does not directly address dependency integrity.

5. Container Image Security

   Which practice best minimizes the security risks associated with using container images in a DevSecOps pipeline?

   1. Disabling all image signature verification steps
   2. Scanning images for vulnerabilities before use
   3. Using only the latest image tags available
   4. Copying images directly from unverified sources

   Explanation: Scanning container images before deploying them enables early detection of known security vulnerabilities and reduces exposure in production. Using only the latest tags does not guarantee security or stability. Downloading images from unverified sources can introduce malicious code. Disabling image signature verification increases risk by making it easier for harmful images to be used unnoticed.
