Abstract
The rise in software development has intensified reliance on complex applications across sectors. However, this growth is paralleled by increased cybersecurity threats, revealing critical vulnerabilities within the Software Development Life Cycle (SDLC). Agile and DevOps methodologies, while offering speed and adaptability, often overlook vital security concerns, thus heightening exposure to cyber risks. This study addresses a novel research gap by examining how discrepancies in security integration across SDLC methodologies can lead to significant gaps in cybersecurity posture. Using a combination of case study scenarios, literature-informed analysis, and focus groups with subject matter experts, this research presents a comprehensive applied approach to cybersecurity in software development. Notably, the study engages participants with advanced expertise and real-world experience, whose insights enhance understanding of secure SDLC integration’s theoretical and practical aspects. This multi-method approach provides emerging cybersecurity professionals with actionable hands-on strategies to identify and mitigate vulnerabilities, aligning with current industry standards. The study’s findings underscore the urgency of standardized security practices within the SDLC, contributing to developing industry-wide best practices prioritizing security alongside speed and flexibility. By bridging theoretical frameworks with applied research, this study offers significant advancements for cybersecurity education and industry practice, preparing future professionals to address evolving cybersecurity challenges effectively.
