BACKGROUND

The increasing sophistication and frequency of cyber threats have rendered traditional cybersecurity measures insufficient. Cyberattacks such as phishing, ransomware, and advanced persistent threats (APTs) now exploit vulnerabilities in complex, interconnected systems, necessitating more robust and adaptive defenses. Artificial intelligence (AI), particularly neural network-based technologies, has emerged as a transformative force in this domain. Neural networks, inspired by the human brain's structure, excel in pattern recognition, anomaly detection, and predictive modeling, making them ideal for combating dynamic and unpredictable cyber threats. Over the past decade, advancements in deep learning have enabled the development of powerful architectures like convolutional neural networks (CNNs) for pattern recognition, recurrent neural networks (RNNs) for sequential data analysis, and generative adversarial networks (GANs) for simulating attack scenarios. These innovations have been integrated into cybersecurity systems to enhance real-time threat detection, automate incident response, and improve overall resilience. Despite their promise, challenges remain, including adversarial attacks that can deceive neural networks, computational overhead, and ethical concerns related to AI's deployment. This background sets the stage for exploring how neural network innovations are transforming cybersecurity by addressing these challenges and providing adaptive, intelligent defenses against evolving threats.
