In recent years the importance of Signals Intelligence (Sigint) has become more prominent, especially the capabilities and possibilities of reading and deciphering diplomatic, military and commercial communications of other nations. This growing awareness of the importance of intelligence applies not only to the activities of the big services but also to those smaller nations like The Netherlands. For this reason The Netherlands Intelligence Association (NISA) was recently established in which academics and (former and still active) members of The Netherlands intelligence community work together in order to promote research into the history of Dutch intelligence communities.--

SIGNALS INTELLIGENCE, or SIGINT, is the interception and evaluation of coded enemy messages. From Enigma to Ultra, Purple to Lorenz, Room 40 to Bletchley, SIGINT has been instrumental in both victory and defeat during the First and Second World War.In the First World War, a vast network of signals rapidly expanded across the globe, spawning a new breed of spies and intelligence operatives to code, de-code and analyse thousands of messages. As a result, signallers and cryptographers in the Admiralty’s famous Room 40 paved the way for the code breakers of Bletchley Park in the Second World War. In the ensuing war years the world battled against a web of signals intelligence that gave birth to Enigma and Ultra, and saw agents from Britain, France, Germany, Russia, America and Japan race to outwit each other through infinitely complex codes. For the first time, Peter Matthews reveals the secret history of global signals intelligence during the world wars through original interviews with German interceptors, British code breakers, and US and Russian cryptographers."SIGINT is a fascinating account of what Allied investigators learned postwar about the Nazi equivalent of Bletchley Park. Turns out, 60,000 crptographers, analysts and linguists achieved considerable success in solving intercepted traffic, and even broke the Swiss Enigma! Based on recently declassifed NSA document, this is a great contribution to the literature." THE ST ERMIN'S HOTEL INTELLIGENCE BOOK OF THE YEAR AWARD 2014.

Presents a history of the agency, from its inception in 1945, to its role in the Cold War, to its controversial advisory position at the time of the Bush administration's search for weapons of mass destruction in Iraq, shortly before the invasion of 2003.

In Code Warriors, Stephen Budiansky--a longtime expert in cryptology--tells the fascinating story of how NSA came to be, from its roots in World War II through the fall of the Berlin Wall. Along the way, he guides us through the fascinating challenges faced by cryptanalysts, and how they broke some of the most complicated codes of the twentieth century. With access to new documents, Budiansky shows where the agency succeeded and failed during the Cold War, but his account also offers crucial perspective for assessing NSA today in the wake of the Edward Snowden revelations. Budiansky shows how NSA's obsession with recording every bit of data and decoding every signal is far from a new development; throughout its history the depth and breadth of the agency's reach has resulted in both remarkable successes and destructive failures.

The National Security Agency is the world’s most powerful, most far-reaching espionage. Now with a new afterword describing the security lapses that preceded the attacks of September 11, 2001, Body of Secrets takes us to the inner sanctum of America’s spy world. In the follow-up to his bestselling Puzzle Palace, James Banford reveals the NSA’s hidden role in the most volatile world events of the past, and its desperate scramble to meet the frightening challenges of today and tomorrow. Here is a scrupulously documented account—much of which is based on unprecedented access to previously undisclosed documents—of the agency’s tireless hunt for intelligence on enemies and allies alike. Body of secrets is a riveting analysis of this most clandestine of agencies, a major work of history and investigative journalism. A New York Times Notable Book

Intelligence and Espionage: Secrets and Spies provides a global introduction to the role of intelligence – a key, but sometimes controversial, aspect of ensuring national security. Separating fact from fiction, the book draws on past examples to explore the use and misuse of intelligence, examine why failures take place and address important ethical issues over its use. Divided into two parts, the book adopts a thematic approach to the topic, guiding the reader through the collection and analysis of information and its use by policymakers, before looking at intelligence sharing. Lomas and Murphy also explore the important associated activities of counterintelligence and the use of covert action, to influence foreign countries and individuals. Topics covered include human and signals intelligence, the Cuban Missile Crisis, intelligence and Stalin, Trump and the US intelligence community, and the Soviet Bloc. This analysis is supplemented by a comprehensive documents section, containing newly released documents, including material from Edward Snowden’s leaks of classified material. Supported by images, a comprehensive chronology, glossary, and 'who’s who' of key figures, Intelligence and Espionage is an invaluable resource for anyone interested in the role of intelligence in policymaking, international relations and diplomacy, warfighting and politics to the present day.

At the dawn of the Cold War, the world’s most important intelligence agencies—the Soviet KGB, the American CIA, and the British MI6—appeared to have clear-cut roles and a sense of rising importance in their respective countries. But when Kim Philby, head of MI6’s Russian division and arguably the twenty-first century’s greatest spy, was revealed to be a Russian mole along with British government heavyweights Donald Maclean and Guy Burgess, everything in the Western intelligence world turned upside down. Here is the true story of how the American James Bond—the colorful, foulmouthed, pistol-packing, alcoholic ex-FBI agent William “King” Harvey—put the finger on Philby; how James Jesus Angleton, the chain-smoking poet of Yale University and the CIA’s supposed “master spy” in charge of counterintelligence, began his descent into a paranoid wilderness of mirrors upon learning of family friend Kim Philby’s ultimate betrayal; and the devastating consequences of the loss of MI6 prestige and the CIA’s subsequent self-defeating witch hunts. Every revelation, every stranger-than-fiction twist and turn is all the more intriguing as truths become lies and unlikely scenarios are revealed as reality. With impeccable sourcing and the use of thousands of pages of declassified research, David C. Martin’s Wilderness of Mirrors is widely recognized as a masterpiece of intelligence literature.
