Cyber attackers are increasingly targeting school systems around the United States. The effects of such attacks worsen as more American schools use technology for teaching. A recent example comes from Connecticut. Cyber attacks cut internet connection to the Avon Public School system several times a day over a six week period. The attackers did not capture sensitive information from the school system. But the damage was still costly. Classroom teaching plans that required the internet were halted. Robert Vojtek is the school system’s technology director. He sought help from the Federal Bureau of Investigation, or FBI. “The first time I called the FBI, their first question was, ‘Well, what did it cost you?’” he said. Vojtek explained that teaching and learning stopped for some 4,000 students. He asked, “How do you put a price tag on that?”
