When, on Wednesday, the New York Stock Exchange halted trading, The Wall Street Journal website went down, and United Airlines grounded flights - all practically at the same time - it
seemed like a well orchestrated cyber attack had been launched against high-profile US businesses and organizations.
As it turned out, the outages were the result of technical problems and network connectivity issues. Still, I bet that for a brief moment, the US government and authorities worried that the moment that many security experts have warned about for years has come: a coordinated, widespread cyber attack against the country and its businesses.
As it happens, insurance market Lloyd's of London has, on the same day, published a research report produced with the help of the University of Cambridge Centre for Risk Studies, which investigates how a severe cyber attack against the US power grid could affect US businesses and what the impact on the US economy would be.
