Applied Network Security Monitoring is the essential guide to becoming an NSM analyst from the ground up. This book takes a fundamental approach to NSM, complete with dozens of real-world examples that teach you the key concepts of NSM.

Network security monitoring is based on the principle that prevention eventually fails. In the current threat landscape, no matter how much you try, motivated attackers will eventually find their way into your network. At that point, it is your ability to detect and respond to that intrusion that can be the difference between a small incident and a major disaster.

The book follows the three stages of the NSM cycle: collection, detection, and analysis. As you progress through each section, you will have access to insights from seasoned NSM professionals while being introduced to relevant, practical scenarios complete with sample data.

If you've never performed NSM analysis, Applied Network Security Monitoring will give you an adequate grasp on the core concepts needed to become an effective analyst. If you are already a practicing analyst, this book will allow you to grow your analytic technique to make you more effective at your job.

Discusses the proper methods for data collection, and teaches you how to become a skilled NSM analyst Provides thorough hands-on coverage of Snort, Suricata, Bro-IDS, SiLK, and Argus Loaded with practical examples containing real PCAP files you can replay, and uses Security Onion for all its lab examples Companion website includes up-to-date blogs from the authors about the latest developments in NSM

The proposed book will assemble a selection of essays that quantify the theories of Pierre Bourdieu. Our purpose is simply to provide a collection of academic pieces that demonstrate how quantitative methodological procedures are used to test the validity of existing social theory, focusing on the prominent sociologist, Pierre Bourdieu. We have chosen Bourdieu due to his international popularity in the sociology discipline, and the extensive range of his theoretical contributions. Demonstrating the importance of quantifying, or testing, theory is frequently overlooked in university courses. Too often the sole focus is either an exploration social theory or a routine of performing quantitative methodological procedures. Students seldom receive exposure to practical applications that clearly illustrate the use of the latter to test the former. The unfortunate consequence is that students often fail to grasp the vital relationship between theory and methods, which is the basis of future sociological research. The majority of single author sociological methods books exist in the form of undergraduate texts.Because sociologists are versed in the basics of quantitative and qualitative methodology, solo academics can reasonably author introductory texts that glean the necessary basics of both quantitative and qualitative methods.However, the same is not true of providing adequate intermediate and advanced level methodological instruction. There is a considerable market for edited volumes of qualitative methodology. The practical benefit of such collections--both for instructors and students--is a selection of diverse topics in which researchers devote considerable attention to specific qualitative procedures. In short, an assortment of contributors can better provide intensive applications of different qualitative procedures that address unique research questions, and in a variety of settings. The end product typically incorporates a useful breadth of sociological topics, but with the requisite methodological depth (i.e. attention to procedure and depth of analysis) that is otherwise difficult for any single author to accomplish. To date, edited volumes of qualitative research are abundant, while similar quantitative compilations are rare.

It s easy to capture packets with Wireshark, the world s most popular network sniffer, whether off the wire or from the air. But how do you use those packets to understand what s happening on your network? Updated to cover Wireshark 2.x, the third edition of Practical Packet Analysis will teach you to make sense of your packet captures so that you can better troubleshoot network problems. You ll find added coverage of IPv6 and SMTP, a new chapter on the powerful command line packet analyzers tcpdump and TShark, and an appendix on how to read and reference packet values using a packet map. Practical Packet Analysis will show you how to: Monitor your network in real time and tap live network communications Build customized capture and display filters Use packet analysis to troubleshoot and resolve common network problems, like loss of connectivity, DNS issues, and slow speeds Explore modern exploits and malware at the packet level Extract files sent across a network from packet captures Graph traffic patterns to visualize the data flowing across your network Use advanced Wireshark features to understand confusing captures Build statistics and reports to help you better explain technical network information to non-techies No matter what your level of experience is, Practical Packet Analysis will show you how to use Wireshark to make sense of any network and get things done.
