Network Security System Optimization Using Blockchain Technology for Data Protection
Keywords:
Blockchain, Network Security, Blockchain, Data Protection, Network SecurityAbstract
Data protection in digital network systems currently faces serious challenges due to the increasing complexity of cyberattacks and the vulnerabilities of conventional security systems that still rely on centralized authority. This study aims to analyze the weaknesses of conventional network security, explore the potential of blockchain technology implementation, develop an optimized blockchain-based network security model, and assess its effectiveness through field trials. A qualitative method was employed using a multi-source data triangulation strategy, including literature review, in-depth interviews with network security and blockchain experts, institutional network system observation, and system documentation analysis. The findings reveal that blockchain holds significant potential in enhancing integrity, transparency, and resilience of network security systems, particularly through decentralization and smart contract features that minimize reliance on single-point authority. The developed model is capable of real-time anomaly detection and data manipulation prevention, and it demonstrated higher effectiveness compared to conventional systems in limited trials. This study concludes that integrating blockchain into network security systems is not merely an alternative solution, but a strategic step toward a more autonomous, decentralized, and adaptive cybersecurity paradigm in response to today’s evolving digital threats
