Firewalls are a staple of almost every network in the world. The firewall protects nearly every network-based transaction that occurs, and even the end user understands its metaphoric name, meant to imply keeping out the bad stuff. But firewalls have had to change. Whether it’s the growth of networks or the growth of network usage, they have had to move beyond the simple devices that only req…

After you’ve spent some time in the networking field, you tend to notice that there is rarely a single way to do things, and in many cases, rarely a single, precise definition for terms. After all, often a network engineer’s best answer is “it depends.” Such is the case with enterprise routing, so let’s start off with a definition question: what is an enterprise network? Is it a large…
This book describes the jobs that I and other networking engineers have performed on client networks over the past few years. We are considered network warriors because of the way that we attack networking challenges and solve issues for our clients. Network warriors come from different backgrounds, including service provider routing, security, and the enterprise. They are experts on many diffe…
Behavioral activation theory indicates that much clinically relevant human behavior is a function of positive reinforcement, and that when positive reinforcement is reduced, lost, or chronically low depression results. Behavioral activation encourages clients to obtain and nurture the skills that allow them to establish and maintain contact with diverse, stable sources of positive reinforcement…
In the last 10 years, network programming has stopped being the province of a few specialists and become a core part of every developer’s toolbox. Today, more pro- grams are network aware than aren’t. Besides classic applications like email, web browsers, and Telnet clients, most major applications have some level of networking built in. For example: • Text editors like BBEdit save and o…
The Windows 8 operating system is the newest member of the Microsoft Windows family. It differs from earlier Windows releases as much for what it does not change as for what it does change. That is, the features that IT pros loved about Windows 7 are still there in Windows 8—just better. The same keyboard shortcuts, management tools, security features, and deployment options are available in …
Financial services companies in the United States are a major industry group, providing five to six million full-time jobs.

Albert Gelpi’s American Poetry after Modernism is a study of major poets of the postwar period from Robert Lowell and Adrienne Rich through the Language poets. He argues that what distinguishes American poetry from the British tradition is, paradoxically, the lack of a tradition; as a result, each poet has to ask fundamental questions about the role of the poet and the nature of the medium, h…
When asking about Information Security (InfoSec), most people immediately think about stolen credit cards, defaced web sites, and teenage hackers with names like B@D@pple. An InfoSec professional might extend the list to items like firewalls, Vir- tual Private Networks (VPN)s, penetration testing, and risk analysis. What is almost never listed is router security—network security, yes, but nev…
We have sometimes joked that there is no good reason to collect new data, given the wealth of existing data sets that can be used to answer important research questions. These existing resources are often longitudinal and usually have sample sizes that are larger than most samples typically found in psychological research. Unfortunately, our enthusiasm for the analysis of secondary data sets su…
If you are to believe the U.S. government, Microsoft Corporation controls a monopoly share of the computer operating system market and possibly many other related software markets as well (web browsers, office productivity software, and so on). And despite continued jeers from its adversaries in the media and the marketplace, Microsoft manages to hold on to this “monopoly” year after year, …
Way back in 1999, the first edition of Hacking Exposed introduced many people to the ease with which computer networks and systems are broken into. Although there are still many today who are not enlightened to this reality, large numbers are beginning to understand the necessity for firewalls, secure operating system configuration, vendor patch maintenance, and many other previously arcane fun…
GNU-Linux is the ultimate hacker’s playground. It’s a toy for the imagination, not unlike a box of blocks or a bag of clay. Whether someone is an artist or a scientist, the possibilities are endless. Anything that you want to try to do and build and make with a computer is subject only to your creativity. This is why so many people are interested in Linux. Many call it Linux instead of GNU-…

In this book, we'll build several projects that will get progressively more challenging. You should be able to build the first few projects in an afternoon. A finished product may take you a while longer, depending on how professional you want it to look. In order to build the first few projects in this book, you will need a few basic assembly skills and tools described as follows. The RF proje…
T he information security (InfoSec) profession got its start decades ago, but it consisted of few people, mostly in military and other secret orga- nizations. With the appearance of the Internet in the 1990s, organizations started to put information online, and the InfoSec profession became a little more popular. Fast‐forward to the mid 2010s, with its big security breaches as well as new law…

n times of crisis, we are forcefully reminded of the links between politics and international economic law.1 Indeed, the meltdown in world markets has refocused attention on how the fingerprints of the “visible hand” can be seen all over the institutions that underpin the rules of globalization. From trade and investment to finance, governments are under pressure to enforce, resist, and rew…
Software that drives the operations of sensors and communication among sensors is basic to any meaningful application of sensor networks. The goal of this book is to provide an understanding of how this software functions; how it allows the sensors to gather information, process it, and interact with each other in networks; and how these networks interact with the physical world. One aim of thi…
