Securing The State

Author: David Omand
Publisher: Oxford University Press
ISBN: 0190612940
Category : Political Science
Languages : en
Pages : 370

Book Description
Governments recognise that national security in the turbulent conditions of the early twenty-first century must centre on the creation of public confidence that normal life can continue even in the face of threats such as terrorism and proliferation, and of natural hazards such as pandemics and climate change. Based on his own experience in government, David Omand argues that while public security is vital for good government, the effects of bad government will result from failure to maintain the right relationship between justice, liberty, privacy, civic harmony and security measures. His book examines in detail how secret intelligence helps governments to deliver security, but also risks raising public concern over its methods. A set of ethical principles is proposed to guide intelligence and security work within the framework of human rights. Securing the State provides a new way of thinking about the cycle of activities that generates secret intelligence, examines the issues that arise from the way that modern intelligence uses technology to access new sources of information, and discusses how the meaning of intelligence can best be elucidated. The limits of intelligence in enabling greater security are explored, especially in guiding government in a world in which we must learn not to be surprised by surprise. Illustrated throughout by historical examples, David Omand provides new perspectives for practitioners and those teaching security and intelligence studies and for a wider readership offers an accessible introduction to pressing issues of public policy.

GCHQ

Author: Nigel West
Publisher: Pen and Sword
ISBN: 1526755793
Category : Political Science
Languages : en
Pages : 398

Book Description
The go-to intelligence expert and author of MI6 has “provided the clearest review of GCHQ and its predecessors in a publicly available book” (Firetrench). Signal intelligence is the most secret, and most misunderstood, weapon in the modern espionage arsenal. As a reliable source of information, it is unequalled, which is why Government Communications Headquarters, almost universally known as GCHQ, is several times larger than the two smaller, but more familiar, organizations, MI5 and MI6. Because of its extreme sensitivity, and the ease with which its methods can be compromised, GCHQ’s activities remain cloaked in secrecy. In GCHQ: The Secret Wireless War 1900-1986, the renowned expert Nigel West traces GCHQ’s origins back to the early days of wireless and gives a detailed account of its development since that time. From the moment that Marconi succeeded in transmitting a radio signal across the Channel, Britain has been engaged in a secret wireless war, first against the Kaiser, then Hitler and the Soviet Union. Following painstaking research, Nigel West is able to describe all GCHQ’s disciplines, including direction-finding, interception and traffic analysis, and code-breaking. Also explained is the work of several lesser known units such as the wartime Special Wireless Groups and the top-secret Radio Security Service. Laced with some truly remarkable anecdotes, this edition of this important book will intrigue historians, intelligence professionals and general readers alike. “Nigel West is an acknowledged expert in this field of literature and his latest book is fascinating and intriguing.” —Books Monthly “Rich in the kind of detail from which all students of radio and military history can learn.” —The Spectrum Monitor

Confronting the Colonies

Author: Rory Cormac
Publisher: Oxford University Press
ISBN: 019936527X
Category : Political Science
Languages : en
Pages : 308

Book Description
Moving the debate beyond the place of tactical intelligence in counterinsurgency warfare, Confronting the Colonies considers the view from Whitehall, where the biggest decisions were made. It reveals the evolving impact of strategic intelligence upon government understandings of, and policy responses to, insurgent threats. Confronting the Colonies demonstrates for the first time how, in the decades after World War Two, the intelligence agenda expanded to include non-state actors, insurgencies, and irregular warfare. It explores the challenges these emerging threats posed to intelligence assessment and how they were met with varying degrees of success. Such issues remain of vital importance today. By examining the relationship between intelligence and policy, Cormac provides original and revealing insights into government thinking in the era of decolonisation, from the origins of nationalist unrest to the projection of dwindling British power. He demonstrates how intelligence (mis-)understood the complex relationship between the Cold War, nationalism, and decolonisation; how it fuelled fierce Whitehall feuding; and how it shaped policymakers' attempts to integrate counterinsurgency into broader strategic policy.

Cyber Mercenaries

Publisher: Cambridge University Press
ISBN: 1108580262
Category : Law
Languages : en
Pages : 267

Book Description
Cyber Mercenaries explores the secretive relationships between states and hackers. As cyberspace has emerged as the new frontier for geopolitics, states have become entrepreneurial in their sponsorship, deployment, and exploitation of hackers as proxies to project power. Such modern-day mercenaries and privateers can impose significant harm undermining global security, stability, and human rights. These state-hacker relationships therefore raise important questions about the control, authority, and use of offensive cyber capabilities. While different countries pursue different models for their proxy relationships, they face the common challenge of balancing the benefits of these relationships with their costs and the potential risks of escalation. This book examines case studies in the United States, Iran, Syria, Russia, and China for the purpose of establishing a framework to better understand and manage the impact and risks of cyber proxies on global politics.

The Spies of Winter

Author: Sinclair McKay

ISBN: 178131618X
Category : History
Languages : en
Pages : 300

Book Description
Following on from the enormous success of his bestseller, The Secret Life of Bletchley Park, renowned author Sinclair McKay uncovers the story of what happened after the end of the Second World War. Once victory was declared, many of the individuals who had achieved the seemingly impossible at Bletchley Park by cracking the impenetrable Enigma codes and giving the Allies an invaluable insight directly into the Nazi war machine, moved on to GCHQ. This was the British government’s new facility established to fight a different, but no less formidable foe – Stalin and the KGB. Fascinating and insightful revelations from deep within the archives of this secret organisation reveal the story of the tumultuous early years of GCHQ as it navigated its way through an era of double agents, deception and betrayals. From the defection of the Cambridge Five and the treachery of the atomic scientist Klaus Fuchs, to the collapse of the British Empire, the ascension of Chairman Mao and the emergence of the US as a superpower, McKay deftly explores the impact these events had on the fledgling organisation. During the years of the Cold War the men and women of GCHQ penetrated Soviet encryptions and gathered crucial intelligence from all over the world. The Spies of Winter tells the story of the codebreakers themselves and how they used new technology to expand the horizons of cryptography in order to defend the nation and maintain the fragile peace in a world now under the shadow of nuclear holocaust.
