Network Analysis

Network analysis is the systematic process of capturing, logging, and interpreting network traffic data to troubleshoot problems, optimize performance, and enhance security. By examining data packets and traffic flows at a granular level, administrators and security professionals can diagnose connectivity issues, identify performance bottlenecks, detect unauthorized or malicious activity, and ensure quality of service (QoS) for critical applications. This deep inspection provides the essential insights needed to maintain a healthy, efficient, and secure computer network infrastructure.
