Traditional intrusion detection and logfile analysis are no longer enough to protect todayβs complex networks. In this practical guide, security researcher Michael Collins shows you several techniques and tools for collecting and analyzing network traffic datasets. Youβll understand how your network is used, and what actions are necessary to protect and improve it.
Divided into three sections, this book examines the process of collecting and organizing data, various tools for analysis, and several different analytic scenarios and techniques. Itβs ideal for network administrators and operational security analysts familiar with scripting.
