This book looks at network security in a new and refreshing way. It guides readers step-by-step through the "stack" -- the seven layers of a network. Each chapter focuses on one layer of the stack along with the attacks, vulnerabilities, and exploits that can be found at that layer. The book even includes a chapter on the mythical eighth layer: The people layer. This book is designed to offer readers a deeper understanding of many common vulnerabilities and the ways in which attacker''s exploit, manipulate, misuse, and abuse protocols and applications. The authors guide the readers through this process by using tools such as Ethereal (sniffer) and Snort (IDS). The sniffer is used to help readers understand how the protocols should work and what the various attacks are doing to break them. IDS is used to demonstrate the format of specific signatures and provide the reader with the skills needed to recognize and detect attacks when they occur. What makes this book unique is that it presents the material in a layer by layer approach which offers the readers a way to learn about exploits in a manner similar to which they most likely originally learned networking. This methodology makes this book a useful tool to not only security professionals but also for networking professionals, application programmers, and others. All of the primary protocols such as IP, ICMP, TCP are discussed but each from a security perspective. The authors convey the mindset of the attacker by examining how seemingly small flaws are often the catalyst of potential threats. The book considers the general kinds of things that may be monitored that would have alerted users of an attack.* Remember being a child and wanting to take something apart, like a phone, to see how it worked? This book is for you then as it details how specific hacker tools and techniques accomplish the things they do. * This book will not only give you knowledge of security tools but will provide you the ability to design more robust security solutions * Anyone can tell you what a tool does but this book shows you how the tool works

The Perfect Reference for the Multitasked SysAdminThis is the perfect guide if network security tools is not your specialty. It is the perfect introduction to managing an infrastructure with freely available, and powerful, Open Source tools. Learn how to test and audit your systems using products like Snort and Wireshark and some of the add-ons available for both. In addition, learn handy techniques for network troubleshooting and protecting the perimeter.* Take InventorySee how taking an inventory of the devices on your network must be repeated regularly to ensure that the inventory remains accurate.* Use NmapLearn how Nmap has more features and options than any other free scanner.* Implement FirewallsUse netfilter to perform firewall logic and see how SmoothWall can turn a PC into a dedicated firewall appliance that is completely configurable.* Perform Basic HardeningPut an IT security policy in place so that you have a concrete set of standards against which to measure. * Install and Configure Snort and WiresharkExplore the feature set of these powerful tools, as well as their pitfalls and other security considerations.* Explore Snort Add-OnsUse tools like Oinkmaster to automatically keep Snort signature files current.* Troubleshoot Network ProblemsSee how to reporting on bandwidth usage and other metrics and to use data collection methods like sniffing, NetFlow, and SNMP.* Learn Defensive Monitoring ConsiderationsSee how to define your wireless network boundaries, and monitor to know if they''re being exceeded and watch for unauthorized traffic on your network.- Covers the top 10 most popular open source security tools including Snort, Nessus, Wireshark, Nmap, and Kismet- Follows Syngress'' proven "How to Cheat" pedagogy providing readers with everything they need and nothing they don''t

An all-star cast of authors analyze the top IT security threats for 2008 as selected by the editors and readers of Infosecurity Magazine. This book, compiled from the Syngress Security Library, is an essential reference for any IT professional managing enterprise security. It serves as an early warning system, allowing readers to assess vulnerabilities, design protection schemes and plan for disaster recovery should an attack occur. Topics include Botnets, Cross Site Scripting Attacks, Social Engineering, Physical and Logical Convergence, Payment Card Industry (PCI) Data Security Standards (DSS), Voice over IP (VoIP), and Asterisk Hacking. Each threat is fully defined, likely vulnerabilities are identified, and detection and prevention strategies are considered. Wherever possible, real-world examples are used to illustrate the threats and tools for specific solutions.* Provides IT Security Professionals with a first look at likely new threats to their enterprise * Includes real-world examples of system intrusions and compromised data * Provides techniques and strategies to detect, prevent, and recover * Includes coverage of PCI, VoIP, XSS, Asterisk, Social Engineering, Botnets, and Convergence

This book is the definitive guide to field epidemiology - the application of epidemiologic methods to unexpected health problems (e.g. bioterrorist attacks, natural disasters, industrial accidents) where rapid, on-site investigation is necessary. The third edition includes new chapters on environmental investigations and immunization strategies and evaluation. Existing chapters on bioterrorism, surveillance, and operations have been completely rewritten. The rest of the chapters have been revised and updated with new case studies and examples.

This book is the definitive guide to field epidemiology- the application of epidemiologic methods to unexpected health problems when a rapid, on-site investigation is necessary. As such, it is an indispensable resource for state and local health agencies and healthcare professionals. This third edition includes a chapter on environmental investigations and one on immunization strategies and evaluation. Chapters have been revised and updated with new cases and examples.
