As technology advances, the transition to cloud enables faster deployments, it is essential that security is embedded at every stage of the software development lifecycle (SDLC). Making security an integral part of the development and deployment process makes security everybody’s responsibility, meaning that vulnerabilities are identified early, product quality is improved, and security does not become a bottleneck to the software delivery process. The integration of security into DevOps results in DevSecOps, and to make that transition successful calls for well-established processes and practices, supported by tools designed for modern technologies and working practices.
A DevSecOps maturity model enables organizations to establish where they are on their journey to DevSecOps, assess their progress toward the ultimate goal, and identify next steps to achieve their objectives.
A maturity model for DevSecOps should address three key areas:
We explore how the DevSecOps maturity model can help deliver business value, as well as the levels of the model and the advantages of each.
The DevSecOps approach enables organizations to produce applications that are secure by design, and deploy them to reliable production environments with all vulnerabilities addressed. This improves business outcomes in terms of productivity and collaboration, as well as building a reputation for products customers can trust. Advancing through the levels of the DevSecOps maturity model brings increasing benefits in terms of:
The DevSecOps maturity model has four levels, the first representing the characteristics of an organization just beginning its DevSecOps journey, the last representing the characteristics of an organization that has embraced DevSecOps fully. The levels should be considered a guide, as the process is more of a continuum than a rigid set of entrance and exit criteria. Importantly, an organization must complete the journey through all levels – it is not possible to achieve and sustain level 4 without completing those which precede it.
Level 1 is the beginning of an organization’s DevSecOps journey, where teams work individually, risk and security are not adequately considered, the majority of tasks are completed manually, and remediation works are typically undertaken post-launch as well as being time-consuming. Little if any regard is given to reviewing what went well, or what could be improved. A change in mindset is required here, emphasizing the importance of collaboration to improve outcomes.
Level 2 marks the true beginning of the DevSecOps journey, where traditional team boundaries begin to blur, and innovation is celebrated. Risk assessments are undertaken frequently and openly, and common tasks are partially automated. Remediation timescales improve, both as a result of earlier detection and some scanning for vulnerabilities and misconfiguration. Platform availability improves with provisioning automation and scaling, as well as basic DR planning. Bottlenecks are reduced, but much security work is still undertaken at the end of the lifecycle.
Level 3 sees productivity and efficiency improve with high quality software products released regularly to reliable platforms. Continuous collaboration and a blameless culture prevail, with comprehensive risk assessment, threat modeling, and security embedded throughout the lifecycle. High levels of automation are present throughout development, testing, and operations, as well as dynamic vulnerability and misconfiguration scanning supporting a weekly release schedule.
Level 4 of the model sees the most advanced organizations build on the three levels above to achieve multiple daily code releases to multiple reliable production environments. Security is no longer a specific domain or team, and its processes and tools are embedded throughout the lifecycle. Very high levels of automation are the hallmark of full adoption of DevSecOps, with threat modeling and assessment, code validation, testing, code scanning, and deployment all highly automated. Infrastructure as code is the expectation, and platforms scale automatically utilizing multiple cloud service providers. The user journey is entirely visible, and informs a highly evolved and innovative development methodology, which consistently delivers high quality and security software products.
