Security from Design, Bridging Model-Driven Architecture and DevSecOps Using Zynerator
We propose an extension to Zynerator, a Model-Driven Architecture framework for automated microservice generation, that embeds DevSecOps principles directly at the modeling stage through semantic decorators. These decorators enable the automated synthesis of secure back-end and front-end components together with operational artifacts, including authentication and authorization modules, audit trails, monitoring dashboards, and DevSecOps pipelines covering SAST, DAST, testing, and deployment. The approach addresses a key limitation of the original Zynerator framework, namely the absence of explicit DevSecOps integration, and supports a security-by-design methodology that reduces reliance on specialized DevSecOps expertise. Through a detailed e-commerce case study and empirical evaluation against manual development and existing Model-Driven Architecture tools, we show that the enhanced framework reduces development effort, strengthens security posture, and accelerates DevSecOps adoption. These findings indicate that DevSecOps-aware model-driven engineering offers a viable pathway toward secure, auto-mated software delivery.
