Voice over IP Security Security best practices derived from deep analysis of the latest VoIP network threats Patrick Park VoIP security issues are becoming increasingly serious because voice networks and services cannot be protected from recent intelligent attacks and fraud by traditional systems such as firewalls and NAT alone. After analyzing threats and recent patterns of attacks and fraud, consideration needs to be given to the redesign of secure VoIP architectures with advanced protocols and intelligent products, such as Session Border Controller (SBC). Another type of security issue is how to implement lawful interception within complicated service architectures according to government requirements. Voice over IP Security focuses on the analysis of current and future threats, the evaluation of security products, the methodologies of protection, and best practices for architecture design and service deployment. This book not only covers technology concepts and issues, but also provides detailed design solutions featuring current products and protocols so that you can deploy a secure VoIP service in the real world with confidence. Voice over IP Security gives you everything you need to understand the latest security threats and design solutions to protect your VoIP network from fraud and security incidents. Patrick Park has been working on product design, network architecture design, testing, and consulting for more than 10 years. Currently Patrick works for Cisco® as a VoIP test engineer focusing on security and interoperability testing of rich media collaboration gateways. Before Patrick joined Cisco, he worked for Covad Communications as a VoIP security engineer focusing on the design and deployment of secure network architectures and lawful interception (CALEA).

Hyde Park, located on Westport's outskirts south of early Kansas City, was the first stop on the long trek down the Santa Fe Trail. Good pasture and a natural cave spring were early attributes. During the real estate boom of the 1880s, the area was platted, but the crash of 1888 intervened, and only a few houses were built. By 1900, with the recovery of the economy and the development of Janssen Place as a private street, the area became the preferred community for Kansas City's wealthy. The architectural style is Queen Anne, Prairie School, Neo-Georgian, Colonial Revival, Kansas City Shirtwaist, and Shingle. These homes glitter with original brass fixtures, lead and stained-glass windows, and oak, mahogany, and walnut interiors. Some of Kansas City's most famous and notorious have lived in Hyde Park, from wealthy businessmen and entertainment stars to serial killers.
A fast-growing frontier community transformed itself into a beautiful urban model of parks and boulevards. In 1893, East Coast newspapers were calling Kansas City the filthiest in the United States. The drainage of many houses emptied into gullies and cesspools. There was no garbage collection service, and herding livestock through the city was only recently prohibited. Through the diligent efforts of a handful of recently arrived citizens, political, financial, and botanical skills were successfully applied to a nascent parks system. Squirrel pastures, cliffs and bluffs, ugly ravines, and shanties and slums were turned into a gridiron of green, with chains of parks and boulevards extending in all directions. Wherever the system penetrated well-settled localities, the policy was to provide playgrounds, tennis courts, baseball diamonds, pools, and field houses. By the time the city fathers were finished, Kansas City could boast of 90 miles of boulevards and 2,500 acres of urban parks.
Before Lincoln Park cemented its trendy reputation, plenty of odd and unruly history managed to settle into its foundation. A Viking ship, mob henchmen and ladies of the evening all took up residence in the same part of town where Dwight L. Moody went from selling soles to saving souls. Thanks to a Confederate ferryboat crewman, many of Lincoln's personal effects belong to the neighborhood named after him. Patrick Butler uncovers Lincoln Park's forgotten contributions to Chicago's heritage, from the "Pleasure Wheel" on Navy Pier to the city's cycling craze.

America's national parks are full of timeless marvels that still rejuvenate the soul: the world's largest trees in Sequoia; its most spectacular geothermal site in Yellowstone; the grandest canyon. Perhaps the movement's most eloquent description that is still resonates came from national parks advocate John Muir: 'Thousands of tired, nerve-shaken, over-civilized people are beginning to find out that going to the mountains is going home; that wildness is a necessity...' Fortunately for the nerve-shaken, over-civilized people of then and now, President Woodrow Wilson created the National Parks Service (NPS) on August 25, 1916, though the drive to protect some of America's most remarkable wild spaces, to be 'used and preserved for the benefit of mankind', began in the 1860s. From Acadia to Zion, this beautiful introduction to America's preserved natural treasures is packed with landscape photography, original wildlife illustrations, and practical information. You will surely be inspired to rediscover these incredible spaces and find out why they're worth celebrating and you'll have all the tools to plan the first of many exciting trips. This book is intended to be a practical introduction to each of America's 59 national parks, distilled by Lonely Planet's expert authors. We highlight the best activities and trails, explain how to get there and where to stay, show you the wildlife to watch out for, and suggest ideal itineraries. Whether you're lucky enough to have a park on your doorstep or need to travel further, we hope that the following pages inspire you both the iconic and lesser-known gems that make up the USA's diversely breathtaking expanses.

The history of the Swiss National Park, from its creation in the years before the Great War to the present, is told for the first time in this book. Unlike Yellowstone Park, which embodied close cooperation between state-supported conservation and public recreation, the Swiss park put in place an extraordinarily strong conservation program derived from a close alliance between the state and scientific research. This deliberate reinterpretation of the American idea of the national park was innovative and radical, but its consequences were not limited to Switzerland. The Swiss park became the prime example of a “scientific national park,” thereby influencing the course of national parks worldwide.

Anna Fisher lives in the exciting City of Atlanta, Georgia, where darkness not only brings out those who prey on others but the young, fearless, adventurous residents and visitors from all walks of society who party all night. Anna's life exists in a very small section of the city where she works and lives. Her dreams are haunted by the man who fathered her child.

To Anna, the little girl is "my stolen child.
After a year of trading colorful barbs with the American president and significant achievements in North Korea's decades-long nuclear and missile development programs, North Korean leader Kim Jong Un declared mission accomplished in November 2017. Though Kim's pronouncement appears premature, North Korea is on the verge of being able to strike the United States with nuclear weapons. South Korea has long been in the North Korean crosshairs but worries whether the United States would defend it if North Korea holds the American homeland at risk. The largely ceremonial summit between US president Donald Trump and Kim Jong Un, and the unpredictability of both parties, has not quelled these concerns and leaves more questions than answers for the two sides' negotiators to work out. The Korean Peninsula's security situation is an intractable conflict, raising the question, "How did we get here?" In this book, former North Korea lead foreign service officer at the US embassy in Seoul Patrick McEachern unpacks the contentious and tangled relationship between the Koreas in an approachable question-and-answer format. While North Korea is famous for its militarism and nuclear program, South Korea is best known for its economic miracle, familiar to consumers as the producer of Samsung smartphones, Hyundai cars, and even K-pop music and K-beauty. Why have the two Koreas developed politically and economically in such radically different ways? What are the origins of a divided Korean Peninsula? Who rules the two Koreas? How have three generations of the authoritarian Kim dictatorship shaped North Korea? What is the history of North-South relations? Why does the North Korean government develop nuclear weapons? How do powers such as Japan, China, and Russia fit into the mix? What is it like to live in North and South Korea? This book tackles these broad topics and many more to explain what everyone needs to know about South and North Korea.

The World War II Battles of Sky, Sand, Snow, Sea, and Shore : as Experienced by a Soldier, a Ship, and Some Spirits Through the Battles of Britain, El Alamein, Stalingrad, the Atlantic, and Normandy
This text recounts the World War II journey's of a soldier, a ship, and a bottle of spirits through, and around, five turning-point battles, constrained more by geography and climate, than by generals and admirals.
Author, intellectual, and social critic, Ralph Ellison (1914-94) was a pivotal figure in American literature and history and arguably the father of African American modernism. Universally acclaimed for his first novel, Invisible Man, a masterpiece of modern fiction, Ellison was recognized with a stunning succession of honors, including the 1953 National Book Award. Despite his literary accomplishments and political activism, however, Ellison has received surprisingly sparse treatment from biographers. Lawrence Jackson’s biography of Ellison, the first when it was published in 2002, focuses on the author’s early life. Powerfully enhanced by rare photographs, this work draws from archives, literary correspondence, and interviews with Ellison’s relatives, friends, and associates. Tracing the writer’s path from poverty in dust bowl Oklahoma to his rise among the literary elite, Jackson explores Ellison’s important relationships with other stars, particularly Langston Hughes and Richard Wright, and examines his previously undocumented involvement in the Socialist Left of the 1930s and 1940s, the black radical rights movement of the same period, and the League of American Writers. The result is a fascinating portrait of a fraternal cadre of important black writers and critics--and the singularly complex and intriguing man at its center.

For generations, visitors, journalists, and social scientists alike have asserted that Chicago is the quintessentially American city. Indeed, the introduction to "The New Chicago" reminds us that to know America, you must know Chicago. The contributors boldly announce the demise of the city of broad shoulders and the transformation of its physical, social, cultural, and economic institutions into a new Chicago. In this wide-ranging book, twenty scholars, journalists, and activists, relying on data from the 2000 census and many years of direct experience with the city, identify five converging forces in American urbanization which are reshaping this storied metropolis. The twenty-six essays included here analyze Chicago by way of globalization and its impact on the contemporary city; economic restructuring; the evolution of machine-style politics into managerial politics; physical transformations of the central city and its suburbs; and race relations in a multicultural era. In elaborating on the effects of these broad forces, contributors detail the role of eight significant racial, ethnic, and immigrant communities in shaping the character of the new Chicago and present ten case studies of innovative governmental, grassroots, and civic action. Multifaceted and authoritative, "The New Chicago" offers an important and unique portrait of an emergent and new Windy City.

Public sector entrepreneurship refers to innovative public policy initiatives that generate greater economic prosperity. These initiatives can transform a status quo economic environment into one that is more conducive to economic units engaging in creative and innovative activities in the face of uncertainty. Public Sector Entrepreneurship traces the historical development of the concepts of private and public sector entrepreneurship and their connection to the separate notions of risk and uncertainty. Based on a formal conceptualization of these notions, the book illustrates throughout public sector entrepreneurship in practice using examples from U.S. technology and innovation policy. Technology policy-policy to enhance the application of new knowledge, learned through science, to some known problem-and innovation policy-policy to enhance the commercialization of a technology-are quintessential examples of the public sector recognizing and exploiting opportunities to bring about change and efficiency. Using this concept of public sector entrepreneurship as the lens to view the Bayh-Dole Act of 1980, the Stevenson-Wydler Act of 1980, the R&E Tax Credit of 1981, Small Business Innovation Development Act of 1982, the National Cooperative Research Act of 1984, and the Omnibus Trade and Competitiveness Act of 1988 affords us the ability to find elements of commonality among these policies and to discuss their impact on the U.S. economy from the perspective of entrepreneurial action.
“This book provides an excellent analysis of regional innovation policy issues and developments with a wealth of examples, notably from OECD countries. Key policy areas, such as clusters, support services, and higher education institutions, are well documented. The research methodology is founded on the experience accumulated by the authors over several decades in many different countries in the context of a world class international organisation. This allows a good selection of policy relevant examples and an experienced presentation of them.” – Jean-Eric Aubert, Former programme manager, World Bank and OECD
Romans loved their gardens, whether they were the grand gardens of imperial country estates or the small private spaces tucked behind city houses. They treasured gardens both as places for relaxation and as plots to grow ornamental plants as well as fruits and vegetables. The soothing sound of bubbling fountains often added further to the pleasures of life in the garden. Romans constructed gardens in every corner of their empire, from Britain to North Africa and from Portugal to Asia Minor. Long after their empire collapsed, the gardens they had so carefully planted continued to exert influence in the farflung corners of their former world. This book describes the variety of Roman gardens throughout the empire, from the humblest to the most lavish, including such well-known places as Hadrian’s Villa in Tivoli and the gardens of Pompeii and Herculaneum. The continued influence of Roman gardens is traced though Arabic, medieval, and Renaissance gardens to the present day. Many of the lavish illustrations were commissioned for this book.
Peter Jobe has just been named the unwilling leader of a study group of four other graduate students whose specialties range from neuroscience to religious studies. The five come from different countries and different disciplines, but they quickly realize the synergy of their ideas could revolutionize the scientific and religious communities. But as Peter's group is beginning to bond, another meeting of the minds is taking place halfway around the world. An unlikely collection of warlords and terrorists have pooled their resources and devised a devastating plan. As the countdown begins, Peter and his friends realize they may be the only ones standing between America and a nuclear holocaust.
There are vampires among us in a shadow world that has its subtle hooks into organized crime itself, as well as practically every major business, governmental, cultural, and religious institution in existence. Subtle, influencing rather than controlling, and ancient, it predates most if not all of the present-day institutions it influences. And evil. No shades of gray here. No redeeming social merit. Most of these vampires are educated, refined and charming, but as pure in their evil as the foulest of their bloodsucking kindred whose transformed faces match their twisted souls. A world of shadows; shadows of evil. When a maverick who prefers the twisted, bloodsucking condition of the classical vampire becomes too powerful to be controlled, a wave of evil is unleashed.
Helen Moran is thirty-two years old, single, childless, college-educated, and partially employed as a guardian of troubled young people in New York. She’s accepting a delivery from IKEA in her shared studio apartment when her uncle calls to break the news: Helen’s adoptive brother is dead. According to the internet, there are six possible reasons why her brother might have killed himself. But Helen knows better: she knows that six reasons is only shorthand for the abyss. Helen also knows that she alone is qualified to launch a serious investigation into his death, so she purchases a one-way ticket to Milwaukee. There, as she searches her childhood home and attempts to uncover why someone would choose to die, she will face her estranged family, her brother’s few friends, and the overzealous grief counselor, Chad Lambo; she may also discover what it truly means to be alive. A bleakly comic tour de force that’s by turns poignant, uproariously funny, and viscerally unsettling, this debut novel has shades of Bernhard, Beckett and Bowles—and it announces the singular voice of Patty Yumi Cottrell.
