Minimizing Microservice Vulnerabilities

Required knowledge for the CKS certification.

Microservices architecture in Kubernetes introduces unique security challenges. Securing microservices requires enforcing secure coding practices, container security, and API protection to reduce exposure to attacks.

This section covers best practices to harden microservices against common vulnerabilities and threats.

Topics Covered​

Secure Development Practices​

Required knowledge for the CKS certification.

  • Implement Static Application Security Testing (SAST) to identify vulnerabilities in code.
  • Enforce peer code reviews to detect security issues early in the development process.

Dependency Management​

Required knowledge for the CKS certification.

  • Regularly update dependencies to patch known vulnerabilities.
  • Use tools like OWASP Dependency-Check, Trivy, or Snyk to scan for outdated or insecure libraries.

Container Security​

Required knowledge for the CKS certification.

  • Scan container images for vulnerabilities before deployment.
  • Use distroless images or minimal base images to reduce the attack surface.

Secure Configuration Management​

  • Avoid hardcoded credentials in configuration files and source code.
  • Use Kubernetes Secrets or external secret management tools like Vault.
