Traffic Analysis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Traffic analysis is the process of intercepting and examining messages in order to deduce information from patterns in communication. It can be performed even when the messages are encrypted and cannot be decrypted. In general, the greater the number of messages observed, or even intercepted and stored, the more can be inferred from the traffic. Traffic analysis can be performed in the context of military intelligence or counter-intelligence, and is a concern in computer security. Traffic analysis tasks may be supported by dedicated computer software programs, including commercially available programs such as those offered by i2, Visual Analytics, Memex, Orion Scientific, Pacific Northwest National Labs, Genesis EW's GenCOM Suite and others. Advanced traffic analysis techniques may include various forms of social network analysis.
