How does Nightingale provide better security?
Everyone knows that it’s a bad idea to have a single point of failure in your network, namely a server or resource whose failure alone disables your network. It’s also a bad idea to have a single data store: You’re taking a big risk if you store data in one place without backing it up in case of a software or hardware failure. By similar reasoning, you cannot achieve the highest level of security if you have a single point of compromise on your network. But that’s exactly what you have with a conventional server. When that one server is compromised, all its secrets and privileges are exposed. (That’s because a hacker compromising a server gets the same access to keys or hardware as the server itself.) In the 2002 annual Computer Security Institute (CSI) “Computer Crime and Security Survey,” which involved 503 computer security practitioners, 90% of respondents reported computer-security breaches within the last twelve months; these were primarily large corporations and government agenc
