The recent attacks on Estonia's internet infrastructure have led to speculation that Estonia may become NATO's cyber warfare test bench. A Defense Ministry IT expert said plans for establishing a NATO cyber defense center in Estonia had existed for over a year and suggested that recent attacks should be considered cyber terrorism. "They should be clearly designated as such because they were instigated by political propaganda which is how terrorist groups find new members." There are plans to begin training Estonian cyber sleuths by the end of 2007.
