What is network traffic analysis?

Network traffic analysis is the process of capturing, monitoring, and analyzing the data packets that flow through a computer network. It involves examining the network traffic patterns, protocols, and behaviors to gain insights into the network's performance, security, and usage.

Network traffic analysis helps in identifying and troubleshooting network issues, detecting and preventing security threats, optimizing network performance, and understanding user behavior. It involves collecting and analyzing various network data, such as packet headers, payload, flow data, and logs, using specialized tools and techniques.

By analyzing network traffic, administrators can identify abnormal or suspicious activities, such as unauthorized access attempts, malware infections, or data breaches. It also helps in monitoring network bandwidth usage, identifying bottlenecks, and optimizing network resources.

Network traffic analysis plays a crucial role in network security, as it enables the detection of network intrusions, malware infections, and other cyber threats. It helps in identifying patterns and signatures of known attacks, as well as detecting anomalies that may indicate new or unknown threats.

Overall, network traffic analysis provides valuable insights into the functioning and security of a computer network, helping administrators make informed decisions, improve network performance, and ensure the overall integrity and reliability of the network.
