Sie können noch so viel in Hardware, Software und Abwehrmechanismen investieren, absolute Sicherheit für Ihre IT-Infrastruktur wird es nicht geben. Wenn Hacker sich wirklich anstrengen, werden sie auch in Ihr System gelangen. Sollte das geschehen, müssen Sie sowohl technisch als auch organisatorisch so aufgestellt sein, dass Sie die Gegenwart eines Hackers erkennen und darauf reagieren können. Sie müssen in der Lage sein, einen Zwischenfall zu deklarieren und die Angreifer aus Ihrem Netzwerk zu vertreiben, bevor sie erheblichen Schaden anrichten. Das ist Network Security Monitoring (NSM). Lernen Sie von dem leitenden Sicherheitsanalytiker Sanders die Feinheiten des Network Security Monitoring kennen. Konzepte verstehen und Network Security Monitoring mit Open-Source-Tools durchführen: Lernen Sie die drei NSM-Phasen kennen, um diese in der Praxis anzuwenden.

Kein Unternehmen kann heute noch komplexe IT-Services marktgerecht aus eigener Kraft bereitstellen. Anwenderunternehmen bedienen sich spezialisierter IT-Dienstleister und letztere greifen auf Komponenten und Dienste aus einem weit gefächerten Zuliefernetzwerk zurück. Dies ist Folge einer zunehmenden Industrialisierung der IT-Produktion, die durch eine starke Arbeitsteilung gekennzeichnet ist. Damit dabei die Sicherheit nicht auf der Strecke bleibt, wird ein unternehmensübergreifendes Sicherheitsmanagement benötigt. Das Buch zeigt, wie Anwenderunternehmen und Lieferanten in einem solchen „Joint Security Management“ organisationsübergreifend kompetent zusammenarbeiten, um sicherzustellen, dass die mit der Nutzung von IT verbundenen Geschäftsrisiken beherrschbar bleiben. Die Autoren erläutern an einem durchgängigen Konzept und einer konkreten, direkt umsetzbaren Gebrauchsanweisung nicht nur das „Was“, sondern auch das „Wie“.

This book examines different aspects of network security metrics and their application to enterprise networks. One of the most pertinent issues in securing mission-critical computing networks is the lack of effective security metrics which this book discusses in detail. Since “you cannot improve what you cannot measure”, a network security metric is essential to evaluating the relative effectiveness of potential network security solutions. The authors start by examining the limitations of existing solutions and standards on security metrics, such as CVSS and attack surface, which typically focus on known vulnerabilities in individual software products or systems. The first few chapters of this book describe different approaches to fusing individual metric values obtained from CVSS scores into an overall measure of network security using attack graphs. Since CVSS scores are only available for previously known vulnerabilities, such approaches do not consider the threat of unknown attacks exploiting the so-called zero day vulnerabilities. Therefore, several chapters of this book are dedicated to develop network security metrics especially designed for dealing with zero day attacks where the challenge is that little or no prior knowledge is available about the exploited vulnerabilities, and thus most existing methodologies for designing security metrics are no longer effective. Finally, the authors examine several issues on the application of network security metrics at the enterprise level. Specifically, a chapter presents a suite of security metrics organized along several dimensions for measuring and visualizing different aspects of the enterprise cyber security risk, and the last chapter presents a novel metric for measuring the operational effectiveness of the cyber security operations center (CSOC). Security researchers who work on network security or security analytics related areas seeking new research topics, as well as security practitioners including network administrators and security architects who are looking for state of the art approaches to hardening their networks, will find this book helpful as a reference. Advanced-level students studying computer science and engineering will find this book useful as a secondary text.
