Cloud-Native Java Application Security through DevSecOps Practices

Abstract

Cloud-native architectures have revolutionized the development and deployment of Java applications by enabling scalability, agility, and faster delivery. These benefits come with significant security challenges due to the distributed, containerized, and dynamic nature of modern systems. Traditional security approaches are no longer sufficient to protect cloud-native Java applications. This paper explores how DevSecOps a methodology that integrates security practices within DevOps workflows addresses these challenges by shifting security left in the software development lifecycle. I examine specific vulnerabilities common in Java-based microservices, the risks introduced by container orchestration platforms, and the complexities of API exposure. The paper outlines how to implement automated security testing, policy enforcement, and compliance checks using tools such as SonarQube, Trivy, Snyk, and GitHub Actions. Case studies illustrate the impact of DevSecOps adoption on vulnerability reduction and operational resilience. I conclude that embedding security into CI/CD pipelines not only mitigates risks but also fosters a culture of shared responsibility and proactive defense, making it essential for securing cloud-native Java applications in today’s fast-evolving threat landscape.
