Network Security Through Data Analysis

Traditional intrusion detection and logfile analysis are no longer enough to protect today’s complex networks. In this practical guide, security researcher Michael Collins shows you several techniques and tools for collecting and analyzing network traffic datasets. You’ll 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. It’s ideal for network administrators and operational security analysts familiar with scripting.Explore network, host, and service sensors for capturing security dataStore data traffic with relational databases, graph databases, Redis, and HadoopUse SiLK, the R language, and other tools for analysis and visualizationDetect unusual phenomena through Exploratory Data Analysis (EDA)Identify significant structures in networks with graph analysisDetermine the traffic that’s crossing service ports in a networkExamine traffic volume and behavior to spot DDoS and database raidsGet a step-by-step process for network mapping and inventory
