Ethereal is the #2 most popular open source security tool used by system administrators and security professionals. This all new book builds on the success of Syngress' best-selling book Ethereal Packet Sniffing.
This book provides complete information and step-by-step Instructions for analyzing protocols and network traffic on Windows, Unix or Mac OS X networks. First, readers will learn about the types of sniffers available today and see the benefits of using Ethereal. Readers will then learn to install Ethereal in multiple environments including Windows, Unix and Mac OS X as well as building Ethereal from source and will also be guided through Ethereal's graphical user interface. The following sections will teach readers to use command-line options of Ethereal as well as using Tethereal to capture live packets from the wire or to read saved capture files. This section also details how to import and export files between Ethereal and WinDump, Snort, Snoop, Microsoft Network Monitor, and EtherPeek. The book then teaches the reader to master advanced tasks such as creating sub-trees, displaying bitfields in a graphical view, tracking requests and reply packet pairs as well as exclusive coverage of MATE, Ethereal's brand new configurable upper level analysis engine. The final section to the book teaches readers to enable Ethereal to read new Data sources, program their own protocol dissectors, and to create and customize Ethereal reports.
Ethereal is the #2 most popular open source security tool, according to a recent study conducted by insecure.org
Syngress' first Ethereal book has consistently been one of the best selling security books for the past 2 years
The companion Web site for the book provides readers with dozens of open source security tools and working scripts
It's easy enough to install Wireshark and begin capturing packets off the wire–or from the air. But how do you interpret those packets once you've captured them? And how can those packets help you to better understand what's going on under the hood of your network? Practical Packet Analysis shows how to use Wireshark to capture and then analyze packets as you take an indepth look at real-world packet analysis and network troubleshooting. The way the pros do it.
Wireshark (derived from the Ethereal project), has become the world's most popular network sniffing application. But while Wireshark comes with documentation, there's not a whole lot of information to show you how to use it in real-world scenarios. Practical Packet Analysis shows you how to:
Use packet analysis to tackle common network problems, such as loss of connectivity, slow networks, malware infections, and more
Build customized capture and display filters
Tap into live network communication
Graph traffic patterns to visualize the data flowing across your network
Use advanced Wireshark features to understand confusing packets
Build statistics and reports to help you better explain technical network information to non-technical users
Because net-centric computing requires a deep understanding of network communication at the packet level, Practical Packet Analysis is a must have for any network technician, administrator, or engineer troubleshooting network problems of any kind.

As recent events demonstrate, the manifestations of Islamist extremism in Europe are manifold. They range from youngsters who reject both government and academic attempts at multiculturalism to radical imams who influence their congregations against their host countries to fundamentalist converts who believe the West is on a crusade to destroy Islam. Chat rooms on the Internet are used with powerful effect to proselytize, recruit, radicalize, fund raise, train, and plot acts of terrorism. In part to counter violent Islamist extremism, the U.S. National Intelligence Strategy seeks to: (1) develop innovative ways to penetrate and analyze the most difficult targets ; and (2) strengthen analytic expertise, methods, and practices; tap expertise wherever it resides; and explore alternative analytic views. Consequently, the director of national intelligence has given top priority to enhancing outreach to the myriad sources of expertise and open source information that can play a decisive role in countering threats such as terrorism. Over the past year, the CSIS Transnational Threats Project operated and tested a global Trusted Information Network (TIN) devoted to critical threat issues demonstrating that structured interaction with nongovernmental experts on the periphery can provide innovative, alternative analysis and perspectives. Islamist extremism in Europe was explored by the TIN s internationally recognized experts, even as daily events in Europe illustrated that al Qaeda inspired terrorists continue to proliferate among Muslim communities there. TIN members, in a collaborative online setting, contributed fresh information and perceptions about the extremists route to violence and their aspirations. This report reviews the workings of the CSIS network and demonstrates the contribution such a TIN can make as a force multiplier for intelligence in the information age.
Technology is an essential part of society in the Information Age. Warfare has always had a technological dimension. In the era of information and the interconnected world, the critical infrastructure of nations has become increasingly reliant upon computer networks: by using the methods of computer network attacks many critical functions of a State could be damaged. This has raised a discussion related to States' national and economic security concerning a new battlefield, warfare in cyberspace.
This report surveys one new facet of technology: computer network attacks, from the framework of the law of armed conflict by asking if the existing law of armed conflict, the main parts of which have their origins in the legacies of two World Wars, applies to computer network attacks. Moreover, the report addresses the questions of the perpetrators of the computer network attacks in the context of the law of armed conflict, what targets can be attacked with the means and methods of computer network attacks and how these attacks should be conducted under the laws of armed conflict.
