Twenty years ago today the nuclear research centre CERN put out a press release announcing that it was making freely available something called the World Wide Web, "a global computer networked informationsystem".
The point is that it would violate this principle to install both a public Web server and an internal support system housing sensitive information on the same virtual server.
The charging documents say a hacker identified as "Sharpie" used information Keys supplied in an Internet chat room to access the Times' websystem and alter a headline on a December 2010 story.
Another example might include an HR generalist using the system to push out upcoming event information or changes to healthcare coverage to a web portal and then alerting staff to the changes via a mass email or other messaging option.
Professor Chapman said the web had made information accessible to millions around the world, but it was very difficult to institute a system of quality of control.
The advantage of instant access to information regardless of device, operating system or location is a huge factor in the dominance of web apps over desktop apps.
