Duncan Hollis, professor of law and associate dean at Temple University Beasely School of Law, discusses cyber security and his recommendation to counter cyber exploits — an electronic SOS. Hollis gives a brief history of online threats, notes the difference between cyber attack and cyber espionage, discusses the difficulty of deterring online exploits due to the anonymity of the internet, and talks about how governments and individuals have responded to cyber threats. He then outlines his proposal — a duty to assist others when they are under duress online — which was inspired by laws of the sea and an episode in which a U.S. Navy warship aided a North Korean vessel that was under attack by Somali pirates.
