If you've never performed NSM analysis, Applied Network Security Monitoring will help you grasp the core concepts needed to become an effective analyst. If you are already working in an analysis role, this book will allow you to refine your analytic technique and increase your effectiveness.

In The Practice of Network Security Monitoring, Mandiant CSO Richard Bejtlich shows you how to use NSM to add a robust layer of protection around your networks no prior experience required. To help you avoid costly and inflexible solutions, he teaches you how to deploy, build, and run an NSM operation using open source software and vendor-neutral tools.

You'll learn how to:

• Determine where to deploy NSM platforms, and size them for the monitored networks
• Deploy stand-alone or distributed NSM installations
• Use command line and graphical packet analysis tools, and NSM consoles
• Interpret network evidence from server-side and client-side intrusions
• Integrate threat intelligence into NSM software to identify sophisticated adversaries

As the sophistication of cyber-attacks increases, understanding how to defend critical infrastructure systems energy production, water, gas, and other vital systems becomes more important, and heavily mandated. Industrial Network Security, Second Edition arms you with the knowledge you need to understand the vulnerabilities of these distributed supervisory and control systems.

The book examines the unique protocols and applications that are the foundation of industrial control systems, and provides clear guidelines for their protection. This how-to guide gives you thorough understanding of the unique challenges facing critical infrastructures, new guidelines and security measures for critical infrastructure protection, knowledge of new and evolving security tools, and pointers on SCADA protocols and security implementation.
