Secure SDLC Frameworks: Leveraging DevSecOps to Enhance Software Security

Abstract

Software applications have become indispensable across sectors, necessitating robust security throughout their lifecycle. This chapter examines transforming the Software Development Life Cycle (SDLC) into a Secure SDLC by embedding security principles at every phase. Through DevSecOps—merging development, operations, and continuous security—organizations strengthen their cyber resilience. A well-structured Secure SDLC with DevSecOps principles mitigates risks while ensuring faster delivery cycles, regulatory compliance, and sustained user trust. The chapter provides methodologies for threat modeling, automation, collaboration, and monitoring, creating a clear pathway for businesses to incorporate security as an integral part of software engineering rather than an afterthought. Through theoretical frameworks and case studies, it demonstrates how security integration drives both protection and business value.
