Harold is the senior security analyst for a small state agency in New York. He has no other
security professionals that work under him, so he has to do all the security-related tasks for the
agency. Coming from a computer hardware background, Harold does not have a lot of experience
with security methodologies and technologies, but he was the only one who applied for the
position. Harold is currently trying to run a Sniffer on the agency’s network to get an idea of what
kind of traffic is being passed around, but the program he is using does not seem to be capturing

technique could Harold use to sniff his agency’s switched network?
