Packet analysis is a primary traceback technique in network forensics, which, providing that the packet details captured are sufficiently detailed, can play back even the entire network traffic for a particular point in time. This solution achieves high accuracy that reaches 99.7% for some botnet types. The size of the packets exchanged between two hosts, details of the systems communicating, time and duration of communication are some of the valuable information to an attacker. 3 Thursday, 1 March 2012.
