Preface

Just like the motto of the Olympic Games—Faster, Higher, Stronger—networks today are faster, wider, and greater. For widespread high-speed networks, carrying greater volumes of data has become a norm rather than the exception. All of these characteristics come with great exposure to a huge variety of threats to the data carried by the networks. The current threat landscape necessitates an increased understanding of the data on our networks, the way we secure it and the tell-tale signs left behind after an incident. This book aims at introducing the subject of network forensics to further help in understanding how data flows across the networks as well as introduce the ability to investigate forensic artifacts or clues to gather more information related to an incident.
