The Facebook project began to unravel in 2008, when a privacy scholar at the University of Wisconsin at Milwaukee, Michael Zimmer, showed that the "anonymous" data of Mr. Kaufman and his colleagues could be cracked to identify the source as Harvard undergraduates.

In Deloitte's sixth annual Global Security Survey, people are the problem. "[P]eople continue to be an organization's greatest asset as well as its greatest worry," Adel Melek, global leader of security and privacy services at Deloitte Touche Tohmatsu, said in the report. "That has not changed from 2007. What has changed is the environment. The economic meltdown was not at its peak when respondents took this survey. If there was ever an environment more likely to facilitate an organization's people being distracted, nervous, fearful, or disgruntled, this is it. To state that security vigilance is even more important at a time like this is an understatement." On one level, that couldn't be more obvious: It's not as if anyone worries about squirrels hacking servers; security has always been about people. (Robots, the report says, are unlikely to replace the human workforce during the lifetime of anyone reading the report. Finally, some good employment news.) Yet despite the obviousness of the problem, the obvious solution -- complete denial of access -- doesn't work. People use computers and computers are more useful when connected and it just gets worse from there. That may explain why identity and access management remained top of mind for survey respondents. Deloitte's survey, drawn from major financial companies around the globe, focuses on governance, investment, risk, use of security technologies, quality of operations, and privacy. It includes some good news -- external breaches have declined sharply over the past year -- and troublesome news -- fewer companies say they have the commitment and funding to address regulatory compliance. In terms of risk, specifically information systems failure, people are identified as the most significant vulnerability. "Human error is overwhelmingly stated as the greatest weakness this year (86%), followed by technology (a distant 63%)," the report states. It attributes the rising risk to increased adoption of new techno
