Traffic analysis is the process of monitoring and evaluating data traffic within a network. It helps identify patterns, trends, and potential issues by examining the flow of data packets. This analysis can be used to optimize network performance, enhance security, and ensure efficient data transmission. In the context of cybersecurity, traffic analysis can reveal suspicious activities or unauthorized access attempts. By analyzing the behavior of data traffic, organizations can detect anomalies and respond to potential threats. Tools and techniques used in traffic analysis include packet sniffers, firewalls, and intrusion detection systems.
