This is a great example of one of the most underestimated insider threat scenarios that I would be worried about if I were managing GRC for an organization.
Three employees of the U.S. State Department, who were properly given access rights to passport files, inappropriately used those rights to access details such as Obama's date and place of birth, e-mail address, mailing address, Social Security number, former names and travel plans. Was this a problem about not having the right policies in place? No. A problem with ineffective controls? No. It's simply a problem of a few people choosing to abuse the trust that had been given them – not out of malice, but simple curiosity (most likely).
Luckily, the State Department has computer-monitoring equipment in place that triggered alarms. And each of the three breaches was identified and dealt with. This incident will serve as a pretty strong deterrent for future curious employees who might otherwise be tempted to try the same thing. And (if this wasn't a government agency) the organization would be able to prove to auditors pretty quickly that they're effectively managing the risk associated to the access rights provided to employees and contractors. Because even when there is risk, they're watching and ready to respond.
Apparently, it was a bipartisan attack.
