abstract = {The rapid expansion of high-speed networks and cloud-integrated systems has made Network Intrusion Detection Systems (NIDS) a cornerstone of modern cybersecurity. While traditional firewalls filter traffic based on predefined rules, NIDS provides an essential layer of "defense-in-depth" by monitoring internal and external traffic for sophisticated patterns of unauthorized access, data exfiltration, and lateral movement. This study presents an analytical overview of evolving NIDS technologies, comparing traditional signature-based methods with modern anomaly-based approaches powered by machine learning. We examine how these systems identify threats such as Distributed Denial of Service (DDoS), zero-day exploits, and insider threats while highlighting the challenges of reducing false-positive rates in high-velocity data environments.},
