Emerging Trends and AI-Driven Defense Mechanisms in Cybersecurity: A Novel Framework for Threat Prediction and Prevention

Abstract

Rapid digital ecosystem growth has made cybersecurity a major issue nowadays. As gadgets, cloud platforms, and critical infrastructures become more interconnected, fraudsters may exploit weaknesses with unparalleled sophistication. Advanced threats including ransomware, deepfake-driven phishing, supply-chain breaches, and AI-powered assaults are beyond firewalls and intrusion detection systems. This paper presents a hybrid cybersecurity system that uses AI, blockchain, and Zero Trust to anticipate, prevent, and mitigate intrusions in real time. Our system uses machine learning to identify anomalies and decentralized, blockchain-based trust management to safeguard data and authentication. A proactive strategy improves detection accuracy, decreases false positives, and builds resistance to emerging threats. Trials utilizing benchmark intrusion detection datasets show that the framework outperforms standard systems. Its use in high-risk industries including banking, healthcare, and industrial IoT is shown by the results. For a safer digital future, our study develops adaptable, intelligent, and scalable cyber protection methods.
