Continuous Container Vulnerability Testing with Trivy

This tutorial emphasizes the importance of integrating security into every stage of a CI/CD workflow by using both proactive and reactive security measures. It introduces Trivy, an open-source security scanner that checks for vulnerabilities and misconfigurations across various components such as code repositories, container images, configuration files, and Infrastructure as Code (IaC). The guide highlights the difference between reactive security, which identifies vulnerabilities in live systems, and proactive security, which aims to prevent vulnerabilities before deployment. The tutorial provides detailed instructions on using Trivy to conduct security checks at multiple stages in the CI/CD pipeline, including scanning dependencies, Docker images, and Kubernetes manifests. It also suggests extending Trivy with plugins and custom policies to better integrate with tools like Kubectl and enforce organizational security rules. While acknowledging that a completely secure system is unattainable, the tutorial advocates for leveraging available tools to minimize security risks.
