Chapter 9: Image Scanning in DevOps Pipelines
It is a good practice to find defects and vulnerabilities in the early stages of the development life cycle. Identifying issues and fixing them in the early stages helps improve the robustness and stability of an application. It also helps to reduce the attack surface in the production environment.

Similar to hardening container images and restricting powerful security attributes in the workload manifest, image scanning can help improve the security posture on the development side. However, image scanning can definitely go beyond that.
In this chapter, first, we will introduce the concept of image scanning and vulnerabilities, then we'll talk about a popular open source image scanning tool called Anchore Engine and show you how you can use it to do image scanning. Last but not least, we will show you how image scanning can be integrated into CI/CD pipelines.
