The rapid digitization of modern infrastructures has significantly expanded the scale and complexity of cyber threats. Traditional security mechanisms, primarily dependent on rule-based detection and centralized monitoring, are increasingly inadequate against sophisticated attacks such as advanced persistent threats (APTs), zero-day exploits, ransomware variants, and AI-driven intrusions. In response to these evolving challenges, this study proposes an intelligent cybersecurity framework that integrates Artificial Intelligence (AI) and Blockchain technology to create a decentralized, adaptive, and resilient security architecture. Artificial Intelligence enhances cybersecurity by enabling real-time anomaly detection, predictive threat intelligence, and automated incident response through machine learning and deep learning models. However, AI-based systems often rely on centralized data repositories, making them vulnerable to manipulation and single points of failure. Blockchain technology addresses these limitations by offering decentralized trust management, tamper-proof logging, immutable audit trails, and smart contract- based policy enforcement. The proposed hybrid framework combines AI's analytical capabilities with blockchain's distributed integrity mechanisms. The architecture includes layered components comprising secure data acquisition, AI-driven intelligence processing, decentralized consensus validation, and administrative control interfaces. The system is evaluated using simulated cyberattack scenarios and benchmark intrusion datasets to assess detection accuracy, response latency, system reliability, and resistance to data tampering. Results indicate that the integrated AI-Blockchain model improves detection precision, reduces false positives, enhances log integrity, and minimizes centralized vulnerabilities compared to standalone AI or blockchain solutions. The research concludes that hybrid intelligent architectures represent a promising direction for next-generation cybersecurity systems capable of protecting critical digital ecosystems.
