INTEGRATING SECURITY INTO THE SOFTWARE DEVELOPMENT LIFECYCLE: A DEVSECOPS PERSPECTIVE

Abstract

 DevSecOps is an emerging paradigm that incorporates security practices into DevOps

and agile software development methodologies. By automating security tasks and integrating tools

at every stage of the continuous integration and continuous delivery (CI/CD) pipeline, DevSecOps

helps organizations detect and remediate vulnerabilities early in the development lifecycle. This

paper reviews key DevSecOps principles, including “shift-left” security and shared responsibility

for security among development, operations, and security teams[1]. We discuss common tools and

methods such as static and dynamic code analysis, dependency (software composition) scanning,

and compliance-as-code that support a secure development pipeline[2][7]. The integration of

security into automated CI/CD processes is examined, with examples of how vulnerability scanning

and testing can be embedded at build and test stages[2][7]. Finally, we consider organizational and

cultural factors, such as training and cross-team collaboration, that are critical to successful

DevSecOps adoption[4][6].
