Secure SDLC: Incorporating Blockchain for Enhanced Security

Abstract

In the rapidly evolving landscape of software development, security has emerged as a critical concern, particularly as the frequency and sophistication of cyber threats continue to rise. The Software Development Life Cycle (SDLC) traditionally emphasizes security at various stages; however, the integration of cutting-edge technologies such as blockchain has the potential to revolutionize this process. This research explores the incorporation of blockchain technology into the Secure SDLC to enhance security measures throughout the software development process. Blockchain, characterized by its decentralized, transparent, and immutable nature, offers a robust framework for mitigating risks associated with software vulnerabilities, data breaches, and unauthorized access. The study delves into how blockchain can be seamlessly integrated into each phase of the SDLC—requirements analysis, design, implementation, testing, deployment, and maintenance. By embedding blockchain protocols within these stages, the SDLC can achieve a higher level of security assurance. For instance, during the requirements analysis and design phases, smart contracts can be utilized to enforce security policies and validate the integrity of design documents. The implementation phase can benefit from blockchain's version control capabilities, ensuring that code changes are tracked, verified, and secure. During testing and deployment, blockchain can facilitate the creation of an immutable audit trail, recording all test results, configurations, and deployments, thereby preventing tampering and ensuring transparency.
