Revealing Secrets
For a long time, the Australian Signals intelligence (or Sigint) story has been kept secret. Until now… Why does Australia have a national signals intelligence agency? What does it do and why is it controversial? And how significant are its ties with key partners, the United States, the United Kingdom, Canada and New Zealand, to this arrangement? Revealing Secrets is a compelling account of Australian Signals intelligence, its efforts at revealing the secrets of other nations, and keeping ours safe. It brings to light those clever Australians whose efforts were for so long entirely unknown or overlooked. Blaxland and Birgin traverse the royal commissions and reviews that shaped Australiaâ€...
A Life in Code
Protesters called it an act of war when the U.S. Coast Guard sank a Canadian-flagged vessel in the Gulf of Mexico in 1929. It took a cool-headed codebreaker solving a "trunk-full" of smugglers' encrypted messages to get Uncle Sam out of the mess: Elizebeth Smith Friedman's groundbreaking work helped prove the boat was owned by American gangsters. This book traces the career of a legendary U.S. law enforcement agent, from her work for the Allies during World War I through Prohibition, when she faced danger from mobsters while testifying in high profile trials. Friedman founded the cryptanalysis unit that provided evidence against American rum runners and Chinese drug smugglers. During World War II, her decryptions brought a Japanese spy to justice and her Coast Guard unit solved the Enigma ciphers of German spies. Friedman's "all source intelligence" model is still used by law enforcement and counterterrorism agencies against 21st century threats.

British Naval Intelligence through the Twentieth Century
This is the first comprehensive account of how intelligence influenced and sustained British naval power from the mid nineteenth century, when the Admiralty first created a dedicated intelligence department, through to the end of the Cold War. It brings a critical new dimension to our understanding of British naval history in this period while setting naval intelligence in a wider context and emphasising the many parts of the British state that contributed to naval requirements. It is also a fascinating study of how naval needs and personalities shaped the British intelligence community that exists today and the concepts and values that underpin it. The author explains why and how intelligen...
Enigma Traitors
Everyone knows the story of Enigma and secret codebreaking in the Second World War: the triumph of Bletchley Park over world-class cipher technology. Except that excellence in codebreaking was nearly betrayed by incompetence in codemaking. German codebreakers were effective and Allied codes and ciphers were weak. With both sides reading each other's codes, the biggest secret of all – that the codes had been broken – was now at risk. Sooner or later, on one side or the other, the cipher failures would become known, the systems would be changed and the most valuable source of intelligence would dry up. Were it not for obstinacy, overconfidence and ostrichism. On both sides. The Germans demanded that the traitors be rooted out; the British stifled cipher questions beneath a tangle of committees. The codebreakers' contest became a struggle to lose the cipher war. From the very outset, the Enigma secret was one of treachery, betrayal and deception. This is the story of the people who fought behind the scenes for cipher security – and of the Enigma traitors.

Intelligence and Surprise Attack
How can the United States avoid a future surprise attack on the scale of 9/11 or Pearl Harbor, in an era when such devastating attacks can come not only from nation states, but also from terrorist groups or cyber enemies? Intelligence and Surprise Attack examines why surprise attacks often succeed even though, in most cases, warnings had been available beforehand. Erik J. Dahl challenges the conventional wisdom about intelligence failure, which holds that attacks succeed because important warnings get lost amid noise or because intelligence officials lack the imagination and collaboration to “connect the dots” of available information. Comparing cases of intelligence failure with intelli...
