DevSecOps as an Integrated Architecture for Modern Software Engineering: Automation, Continuous Security, and Organizational Resilience

Abstract

DevSecOps has emerged as a foundational paradigm in contemporary software engineering, integrating development, operations, and security practices into a continuous and automated workflow. This article presents a conceptual and documentary review of the theoretical and practical evolution of DevSecOps as an integrated architecture for organizations seeking resilience, scalability, and protection against increasingly sophisticated threats. The study examines core principles of the model, including continuous integration, continuous delivery, automated testing, infrastructure as code, and intelligent monitoring. It also analyzes the incorporation of security controls from the earliest stages of the software development lifecycle, contrasting this approach with traditional models in which security was added at the end of the process. The methodology combines a systematic documentary review with a comparative analysis of DevOps, SecOps, and DevSecOps models, enabling the identification of structural, operational, and cultural differences. Findings indicate that DevSecOps not only reduces vulnerabilities but also enhances organizational efficiency through automated pipelines and collaborative practices. Practical applications are highlighted in sectors such as banking, healthcare, and government services, where security is critical. The study also discusses limitations related to organizational culture, adoption costs, and shortages of specialized talent. The analysis concludes that DevSecOps constitutes an essential approach for organizations aiming to develop secure, agile, and sustainable software in highly dynamic environments.
