Traffic analysis - Wikipedia Network traffic analysis is an essential way to monitor network availability and activity to identify anomalies, maximize performance, and keep an eye out for attacks. Luckily, Loggly has a tool for anomaly detection. By studying the timing of the messages going through the mixes it is possible for the attacker to determine the mixes that form a communication path. Network traffic analysis also leverages entity tracking to understand the source and destination assets better, thus providing more detailed reports to users. An active attack involves using information gathered during a passive attack to compromise a user or network. Protecting against them requires solutions that can translate this intelligence into actions that prevent the attack from succeeding. Types of Passive attacks are as follows: The release of message content; Traffic analysis; The release of message content - Telephonic conversation, an electronic mail message, or a transferred file may contain sensitive or confidential information.
