Since the attacks of 9/11, the United States Intelligence Community (IC) has undergone an extensive overhaul. Perhaps the greatest of these changes has been the formation of the Office of the Director of National Intelligence. As a cabinet-level official, the Director oversees the various agencies of the IC and reports directly to the President. The IC today faces challenges as it never has before; everything from terrorism to pandemics to economic stability has now become an intelligence issue. As a result, the IC is shifting its focus to a world in which tech-savvy domestic and international terrorists, transnational criminal organizations, failing states, and economic instability are now a way of life.

Introduction to Intelligence Studiesprovides a comprehensive overview of intelligence and security issues, defining critical terms, and reviewing the history of intelligence as practiced in the United States. Designed in a practical sequence, the book begins with the basics of intelligence, progresses through its history, describes best practices, and explores the way the IC looks and operates today. Each chapter begins with objectives and key terms and closes with questions to test reader assimilation.

The authors examine the "pillars" of the American intelligence system--collection, analysis, counterintelligence, and covert operations--and demonstrate how these work together to provide "decision advantage." The book provides equal treatment to the functions of the intelligence world--balancing coverage on intelligence collection, counterintelligence, information management, critical thinking, and decision-making. It also covers such vital issues as laws and ethics, writing and briefing for the IC, and the emerging threats and challenges that intelligence professionals will face in the future.
