RootLogChain: Registering Log-Events in a Blockchain for Audit Issues from the Creation of the Root

Area of Science:

• Computer Science
• Cybersecurity
• Distributed Systems

Background:

• System logging is crucial for organizational credibility and requires protection from the root user to ensure data integrity.
• Securing logs from privileged users is essential for maintaining trust and auditability in computer systems.

Purpose of the Study:

• To introduce RootLogChain, a novel blockchain-based audit mechanism for securing system logs.
• To establish a robust security protocol for creating a unique root user and logging all root events immutably on a blockchain.

Main Methods:

• Developed a prototype of RootLogChain utilizing a microservice architecture.
• Validated the mechanism through stress tests in scenarios with compliant and non-compliant agents, simulating eavesdroppers.

Main Results:

• Guaranteed the creation of a single, unique root user.
• Ensured the integrity and authenticity of all blockchain transactions and stored root events.
• Demonstrated traceability of transaction logs for audit purposes.

Conclusions:

• RootLogChain effectively secures system logs in distributed and hostile environments.
• The blockchain-based approach ensures a single root user and provides tamper-proof audit trails.
• The mechanism is validated for its ability to maintain log integrity and authenticity.
