Estrategia de trazabilidad de elementos de seguridad a través del ciclo de vida del software usando el modelo cascada
(Universidad EAFIT, 2025) Zuluaga Ossa, David Ricardo; Vallejo Correa, Paola Andrea; Correa Botero, Daniel
Security in software development is a critical concern that must be addressed throughout the entire software development lifecycle (SDLC). Effective integration of security practices is essential to ensure system integrity, confidentiality, and availability. Existing frameworks such as Secure SDLC, OWASP, and ISO/IEC 27034 promote the incorporation of security from the early stages of development. However, these methodologies often overlook the continuous traceability of security requirements, particularly within sequential models like the waterfall model, where the lack of iterative feedback limits visibility and adaptability across phases. This work proposes a traceability strategy tailored to the waterfall model as described by Sommerville, focusing on linking security requirements from their initial specification through design, implementation, and testing. The proposed approach facilitates early detection of omissions and deviations, enhances consistency and quality in deliverables, supports auditing and compliance verification, and reduces the costs associated with late-stage security fixes. Furthermore, it fosters stakeholder confidence by providing transparent evidence of secure and structured development practices across the project lifecycle.
