End-to-End Software Security Strategies for Enterprise Applications

Abstract

This paper presents a comprehensive end-to-end software security strategy designed specifically for large-scale enterprise applications. Building upon the robust quality assurance framework introduced by Banik and Kothamali (2019), the strategy embeds security validation checkpoints across every phase of the software development lifecycle (SDLC)including planning, coding, integration, testing, deployment, and post-production monitoring. Emphasizing proactive threat mitigation and continuous security reinforcement, this approach ensures that vulnerabilities are identified and addressed early and consistently. The proposed framework was implemented and assessed in two critical enterprise systems: a banking transaction engine and a healthcare analytics suite. Evaluation results revealed significant enhancements in early risk detection, alignment with industry-standard security compliance measures, and overall efficiency in managing vulnerabilities. These findings affirm the adaptability, relevance, and lasting impact of the Banik-Kothamali QA model in securing modern, complex enterprise-grade software environments.
