Securing Logs and Metrics in DevOps Using Blockchain: Enhancing Trust and Integrity in Continuous Deployment

In today's constantly evolving DevOps environment, log and metric security is critical to maintaining the trust and integrity of continuous deployment pipelines. When it comes to protecting against tampering and unauthorized access of logs and metrics, traditional methods often fall short. However, traditional approaches frequently encounter challenges related to security, transparency, and reliability. Within this framework, blockchain technology presents itself as an effective way of improving the security and integrity of log and metric data within DevOps processes. This paper explores how to secure logs and metrics in DevOps using blockchain technology, specifically Ethereum with Solidity programming, to improve trust and integrity in continuous deployment processes. We talk about the planning and execution of a blockchain-based system that monitors and logs DevOps pipeline activity. Our method ensures tamper-proof storage, transparent auditing, and precise access control for log and metric data by utilizing smart contracts and decentralized ledger technology. We demonstrate a prototype implementation and evaluate how well it improves accountability, integrity, and security of data. Our research shows how blockchain technology can be used to solve important issues with DevOps logging and monitoring, creating the way to more secure and reliable continuous deployment processes.
