A Comprehensive Investigation into Integrating Artificial Intelligence and Machine Learning for Enhanced Cybersecurity

People, businesses, and vital infrastructure are at serious danger from the sophisticated and persistent cyberthreats that have emerged as a result of the quickly changing digital world. Modern attack vectors including ransomware, polymorphic malware, advanced persistent threats (APTs), and zero-day vulnerabilities are outperforming traditional cybersecurity systems, which mostly depend on predetermined rules and signature-based detection. As a result, machine learning (ML) and artificial intelligence (AI) have become game-changing technologies that may improve cyber defences via predictive analytics, intelligent automation, and flexibility. The integration of AI and ML into cybersecurity frameworks is examined in this paper, with a focus on how these technologies might improve threat prevention, detection, and response capabilities. Predictive threat modelling, which uses historical and real-time data to predict possible breaches; behavior-based anomaly detection, which spots suspicious activity outside of known attack patterns; automated incident response, which allows for quick threat containment and remediation; and proactive risk assessment, which aids in well-informed security policy decisions, are some of the main application areas. In addition to discussing cutting-edge techniques and technologies now in use, the article offers a systematic analysis of current issues, including model explainability, data quality issues, and adversarial assaults on AI systems.
