In this paper, I showed two main areas of intelligence activity: surveillance and economic espionage. I gave background information, described traditional and modern methods and technologies used for these purposes, and covered main aspects of both areas.
I had decided to cover two related but different areas, because of the current relevance of both of them. Whereas surveillance is more about how to gain information, espionage, especially economic espionage, is more about how to get an advantage out of the information obtained.
Several important issues exist that I could not cover. These include, for example, privacy concerns and means for protection against surveillance and espionage.
Intelligence agencies live in a world of their own. They are not controlled by parliaments but posses technologies that give them potentially emense power. In public, little is known about the activities of the intelligence community. With this paper, I wanted to give an impression of a small part of intelligence agencies' work and how this can potentially affect everybody's life, both as an individual and as part of a company.
