Chapter 1, Introducing DevSecOps, discusses the basics of DevSecOps and the different maturity levels involved in the current state and future attainable state of the practices involved in DevSecOps. It helps organizations understand where they are and where things can be taken next. People are the most important element in any technology and process. You can use the best of technology and processes, but without people, goals can’t be achieved. In this chapter, we will learn about the involvement of different teams and what key performance indicators are.
Chapter 2, DevSecOps Principles, explores the DevSecOps principles, which are the key concepts to pick up a program at any point of the development cycle and take it to the maturity stage.
Chapter 3, Understanding the Security Posture, covers the understanding your security posture of DevSecOps pipeline within an organization. We will also be covering what measures are we taking to secure the environment and why, what measures can we take to monitor an environment?, and where does security stand in the whole development process?
Chapter 4, Understanding Observability, examines what observability is and how it is different from monitoring. Also, we will look at how observability helps DevSecOps.
Chapter 5, Understanding Chaos Engineering, covers the aspects of chaos engineering and how data is fed to a system, well as understanding how the system fails.
Chapter 6, Continuous Integration and Continuous Deployment, discusses what is CI/CD, the benefits of CI/CD, how we can automate the CI/CD pipeline, and the importance of the CI/CD pipeline.
Chapter 7, Threat Modeling, dives into threat modeling, which involves examining applications through the eyes of an attacker in order to identify and highlight security flaws that could be exploited. This makes security a part of the organizational culture, laying the groundwork for a DevSecOps workplace. Threat modeling also helps teams better understand and learn each other’s roles, objectives, and pain points, resulting in a more collaborative and understanding organization. The chapter also covers the free and open source tools for threat modeling.
Chapter 8, Software Composition Analysis (SCA), explores third-party dependencies, which are one of the biggest concerns when we deal with code. Some 80–90 percent of software code contains third-party dependencies or libraries. These dependencies come with their own issues and benefits. In this chapter, we will discuss software composition analysis and its uses. We also cover the free and open source tools for SCA.
Chapter 9, Static Application Security Testing (SAST), examines SAST, which happens early in the Software Development Life Cycle (SDLC) because it does not require a working application and can be performed without executing any code. The chapter also covers the free and open source tools for SAST.
Chapter 10, Infrastructure-as-Code (IaC) Scanning, discusses Infrastructure-as-Code (IaC) scanning, which looks for known vulnerabilities in your IaC configuration files. IaC improves usability and functionality while also assisting developers with infrastructure deployment. The chapter will share the aspects of IaC scanning and usability testing. The chapter also covers the free and open source tools for IaC.
Chapter 11, Dynamic Application Security Testing (DAST), delves into DAST, which is the process of analyzing a web application from the frontend to find vulnerabilities. A DAST scanner looks for results that aren’t part of the expected result set and detects security flaws. The chapter also covers the free and open source tools for DAST.
Chapter 12, Setting Up a DevSecOps Program with Open Source Tools, covers the tools and tips to set up an effective DevSecOps program, covering it from 360 degrees.
Chapter 13, Licenses Compliance, Code Coverage, and Baseline Policies, explores license compliance, which ensures we manage licenses and policies and keep them up to date.
Chapter 14, Setting Up a Security Champions Program, talks about who security champions are and how we can set up a security champions program.
Chapter 15, Case Studies, discusses case studies from organizations that have set up DevSecOps programs. What were the initial setbacks that eventually contributed to the DevSecOps program's success ? We look at the lessons learned along the way.
Chapter 16, Conclusion, concludes the book, focusing on what we have learned from the different chapters and offering a call to action on the way forward.
