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 data Store data traffic with relational databases, graph databases, Redis, and Hadoop Use SiLK, the R language, and other tools for analysis and visualization Detect unusual phenomena through Exploratory Data Analysis (EDA) Identify significant structures in networks with graph analysis Determine the traffic that’s crossing service ports in a network Examine traffic volume and behavior to spot DDoS and database raids Get a step-by-step process for network mapping and inventory

Das Thema Cybersecurity ist so aktuell wie nie, denn im Cyberspace lassen sich nur schwer Grenzen in Bezug auf den Zugang zu Informationen, Daten und Redefreiheit setzen. Kriminelle nutzen die Lücken oft zu ihrem Vorteil aus. Die Vielzahl der IT-Systeme, ihre unterschiedlichen Nutzungsarten und ihre Innovations- und Lebenszyklen haben zu hohen Sicherheitsrisiken für Unternehmen und staatliche Einrichtungen geführt. Diese Risiken werden sich auch langfristig nicht so einfach aus der Welt schaffen lassen. Daher müssen Institutionen Strategien und Lösungen zu ihrem Selbstschutz entwickeln. Dieses Buch beschreibt Lösungsansätze und Best Practices aus den unterschiedlichsten Bereichen, die nachweislich zu einer höheren Resilienz gegenüber Cyberangriffen führen. Weltweit renommierte IT-Sicherheitsexperten berichten in 40 Beiträgen, wie sich staatliche Institutionen, unter anderem das Militär (Cyber Defence), Behörden, internationale Organisationen und Unternehmen besser gegen Cyberangriffe schützen und nachhaltige Schutzstrategien entwickeln können. Die Autoren widmen sich den Gründen und Zielen, die ihren jeweiligen Strategien zugrunde liegen, sie berichten, wie Unternehmen auf konkrete Cyberattacken reagiert haben und wie einzelne staatliche Institutionen angesichts nationaler Cyberstrategien agieren. In weiteren Kapiteln zeigen Wissenschaftler auf, was bei der Abwehr von Cyber-Attacken bereits heute möglich ist, welche Entwicklungen in Arbeit sind und wie diese in Zukunft eingesetzt werden können, um die Cyber-Sicherheit zu erhöhen. Im letzten Kapitel berichten Hersteller, Anwenderunternehmen und Dienstleister welche Best Practices sie in ihren Unternehmen eingeführt haben und wie andere Unternehmen ihrem Beispiel folgen können. Das Buch richtet sich an IT-Verantwortliche und -Sicherheitsbeauftragte in Unternehmen und anderen Organisationen, aber auch an Studierende in den verschiedenen IT-Studiengängen.

Networked computers are ubiquitous, and are subject to attack, misuse, and abuse. One method to counteracting this cyber threat is to provide security analysts with better tools to discover patterns, detect anomalies, identify correlations, and communicate their findings. Visualization for computer security (VizSec) researchers and developers are doing just that. VizSec is about putting robust information visualization tools into the hands of human analysts to take advantage of the power of the human perceptual and cognitive processes in solving computer security problems. This volume collects the papers presented at the 4th International Workshop on Computer Security - VizSec 2007.
