Network Intrusion Detection System

Abstract

Network intrusion detection systems (NIDS) play a crucial role in safeguarding network infrastructures against unauthorized access and malicious activities. This abstract explores the fundamental concepts, methodologies, and challenges associated with NIDS. It delves into the various techniques employed by NIDS, ranging from signature-based detection to anomaly detection, and highlights the importance of real-time monitoring and analysis for timely threat detection and response. Additionally, the abstract discusses the evolving landscape of cyber threats and the need for continuous adaptation and enhancement of NIDS to mitigate emerging risks effectively. Furthermore, it addresses the trade-offs between detection accuracy, resource utilization, and scalability, emphasizing the significance of striking a balance to ensure optimal NIDS performance in diverse network environments. Overall, this abstract provides a comprehensive overview of NIDS, underscoring its indispensable role in fortifying network security posture in the face of evolving cyber threats.
