Motivation for This Book The OPC Foundation provides specifications for data exchange in industrial au- mation. There is a long history of COM/DCOM-based specifications, most pro- nent OPC Data Access (DA), OPC Alarms and Events (A&E), and OPC Historical Data Access (HDA), which are widely accepted in the industry and implemented by almost every system targeting industrial automation. Now the OPC Foundation has released a new generation of OPC specifications called OPC Unified Architecture (OPC UA). With OPC UA, the OPC Foundation fulfills a technology shift from the retiring COM/DCOM technology to a servi- oriented architecture providing data in a platform-independent manner via Web Services or its own optimized TCP-based protocol. OPC UA unifies the previous specifications into one single address space capable of dealing with current data, alarms and events and the history of current data as well as the event history. A remarkable enhancement of OPC UA is the Address Space Model by which v- dors can expose a rich and extensible information model using object-oriented techniques. OPC UA scales well from intelligent devices, controllers, DCS, and SCADA systems up to MES and ERP systems. It also scales well in its ability to provide information; on the lower end, a model similar to Classic OPC can be used, providing only base information, while at the upper end, highly sophisticated models can be described, providing a large amount of metadata including complex type hierarchies.

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

“What a di?erence a year makes – 52 little weeks” This variation of the ?rst line from Dinah Washington’s famous song, which originally reads, “What a di?erence a day makes - 24 little hours,” brings it to the point: Accordingtoallexperts,thepress,andmostpeople’simpressionwearetoday in a serious economic recession. Less than one year ago, we practically lived on the “island of the blessed” (namely, at Networking 2008 that was held on the island of Singapore), or in the famous country where “milk and honey ?ow” (or “where wine and liquor ?ow”). This convenient situation has changed abruptly within less than 52 weeks. It looks like the same kind of problems has emerged in all areas – and the “Networking” area has, of course, been a?ected, too. Looking into the 2009 proceedings, however, you will immediately notice that the manuscripts are largely una?ected by any aspect of the economic c- sis (which should be a bit of a consolation). Apparently, research directions are dictated by a process that is all too sluggish in order to be quickly and radically changed by a “tsunami.” Likewise, the conference itself was prepared in spite of such a crisis.

From the acclaimed novelist and screenwriter of The Theory of Everything comes a revelatory look at the period immediately following Winston Churchill’s ascendancy to Prime Minister—soon to be a major motion picture starring Gary Oldman. “He was speaking to the nation, the world, and indeed to history...” May, 1940. Britain is at war. The horrors of blitzkrieg have seen one western European democracy after another fall in rapid succession to Nazi boot and shell. Invasion seems mere hours away. Just days after becoming Prime Minister, Winston Churchill must deal with this horror—as well as a skeptical King, a party plotting against him, and an unprepared public. Pen in hand and typist-secretary at the ready, how could he change the mood and shore up the will of a nervous people? In this gripping day-by-day, often hour-by-hour account of how an often uncertain Churchill turned Britain around, the celebrated Bafta-winning writer Anthony McCarten exposes sides of the great man never seen before. He reveals how he practiced and re-wrote his key speeches, from ‘Blood, toil, tears and sweat’ to ‘We shall fight on the beaches’; his consideration of a peace treaty with Nazi Germany, and his underappreciated role in the Dunkirk evacuation; and, above all, how 25 days helped make one man an icon. Using new archive material, McCarten reveals the crucial behind-the-scenes moments that changed the course of history. It’s a scarier—and more human—story than has ever been told. “McCarten's pulse-pounding narrative transports the reader to those springtime weeks in 1940 when the fate of the world rested on the shoulders of Winston Churchill. A true story thrillingly told. Thoroughly researched and compulsively readable.”—Michael F. Bishop, Executive Director of the International Churchill Society
