Book excerpt: This quick read book defines the DevSecOps Transformation Control Framework. Providing security control checklists for every phase of DevSecOps. Detailing a multidisciplinary transformation effort calling to action the Governance, Risk, and Compliance teams, along with security, auditors, and developers. The uniqueness of these checklists lies in their phase-specific design and focus on aligning security with the team's existing way of working. They align the skills required to execute security mechanisms with those of the team executing each phase. Asserting that a close alignment, is less disruptive to the team's way of working, and consequently more conducive to maintaining the delivery speed of DevSecOps. The checklists encapsulate alignment initiatives that first enhance tried and tested security processes, like data risk assessments, threat analysis and audits, keeping their effectiveness but adapting them to the speed of DevSecOps. Secondly, it uses container technologies as catalysts to streamline the integration of security controls, piggy-backing off the automated progression of containers through the pipeline, to automate the execution and testing of security controls. Providing a blueprint for organisations seeking to secure their system development approach while maintaining its speed.
