As cyber attacks dominate front-page news, as hackers join the list of global threats, and as top generals warn of a coming cyber war, few books are more timely and enlightening than Dark Territory: The Secret History of Cyber War by Slate columnist and Pulitzer Prize-winning journalist Fred Kaplan.

The National Security Agency was born out of the legendary codebreaking programs of World War II that cracked the famed Enigma machine and other German and Japanese codes, thereby turning the tide of Allied victory. In the postwar years, as the United States developed a new enemy in the Soviet Union, our intelligence community found itself targeting not soldiers on the battlefield, but suspected spies, foreign leaders, and even American citizens.

Eyes in the Sky is the authoritative account of how the Pentagon secretly developed a godlike surveillance system for monitoring America's enemies overseas, and how it is now being used to watch us in our own backyards. Whereas a regular aerial camera can only capture a small patch of ground at any given time, this system - and its most powerful iteration, Gorgon Stare - allow operators to track thousands of moving targets at once, both forwards and backwards in time, across whole city-sized areas.

John A. Gentry and Joseph S. Gordon update our understanding of strategic warning intelligence analysis for the 21st century. Strategic warning - the process of long-range analysis to alert senior leaders to trending threats and opportunities that require action - is a critical intelligence function. It also is frequently misunderstood and underappreciated. The authors examine historical case studies, including postmortems of warning failures, to provide examples of the analytic points they make.

This classic of spycraft is based on Allen Dulles's incomparable experience as a diplomat, international lawyer, and America's premier intelligence officer. Dulles was a high-ranking officer of the CIA's predecessor - the Office of Strategic Services - and was present at the inception of the CIA, where he served eight of his 10 years there as director. Here he sums up what he learned about intelligence from nearly a half-century of experience in foreign affairs.
