Abstract
In modern software development, the rapid adoption of practices such as DevOps, Agile, and Continuous Integration/Continuous Deployment (CI/CD) pipelines has introduced significant privacy vulnerabilities. This study investigates these vulnerabilities, particularly in areas such as API security, insider threats, and weak access control, which have become prevalent as organizations prioritize speed and efficiency over comprehensive security checks. The study also evaluates the effectiveness of key cybersecurity solutions, including the Secure Software Development Life Cycle (SSDLC), DevSecOps, and end-to-end encryption, in mitigating these risks. By analyzing real-world case studies, interviews, and surveys, the research identifies best practices such as secure coding guidelines, role-based access control (RBAC), and continuous security testing as critical measures for safeguarding user privacy. The statistical analysis reveals a strong correlation between the adoption of these solutions and a reduction in privacy breaches. The findings emphasize the need for integrating security into every phase of the software development lifecycle to protect sensitive data and ensure privacy compliance.
