    Blockchain based configuration files backup system
    (Faculty of Engineering and Natural Science, 2024) Shakhnazar S.M.
    In today’s digital age, the need for robust data security and backup systems has become increasingly critical, especially in the face of rising cyber threats such as ransomware attacks. Traditional backup systems have shown vulnerabilities in safeguarding crucial data, prompting a search for innovative solutions to enhance data integrity and protection. This research presents a groundbreaking approach to address the challenges in data security and backup systems by leveraging blockchain technology. Blockchain technology, renowned for its decentralized and immutable nature, offers a secure and transparent platform for storing and safeguarding data. By harnessing the programmable and decentralized features of blockchain, this thesis proposes a novel blockchain-based configuration files backup system. The system aims to ensure the confidentiality and integrity of data backups in network environments, paving the way for enhanced network security measures. The research questions aim to explore how blockchain technology can be utilized to enhance the security of configuration files backup systems, the advantages of implementing a blockchain-based backup system over traditional methods, the impact of blockchain technology on cybersecurity innovation and data protection mechanisms, and how blockchain technology can contribute to the expansion of information security and improve overall data resilience in network environments. The methodology section delves into the fundamentals of blockchain technology, explaining different types of blockchain networks, consensus protocols, proof of work, and asymmetric encryption. The proposed system includes a detailed system architecture, data storage mechanisms, and blockchain algorithms for securing data and configuration files. Through experimentation and evaluation of the proposed system, the effectiveness of protecting data against vulnerabilities in real-world scenarios, including ransomware attacks, integration of blockchain, and evaluation of performance are analyzed. This thesis aims to make significant contributions to the field of information security by showcasing the transformative capabilities of blockchain technology in enhancing data security innovation, fostering data resilience in network environments, and advancing network security practices in the digital era.
