Book excerpt: With new security threats practically every week all over the globe, governments and businesses are forced to take extraordinary measures to protect themselves these days. Likewise, espionage continues at levels comparable to the days of the Cold War—only with many more players now participating. In this environment, a new industry has grown to deal with these challenges: international security consulting. Drawing from military, law-enforcement, and intelligence communities, new private companies are springing up across the world. Global Security Consulting, written by a former intelligence specialist who has built a successful practice, provides solid guidance for anyone wishing to enter this glamorous but often dangerous field.
