In organizations that aren't sophisticated with measuring the value of risk, getting budget for security can be a tough gig. SC Magazine has an entire blog dedicated to an active running list of publicly known breaches, yet no matter how many examples you show, sometimes the logic that it will never be you is just a wishful thinking phenomenon that can't be beat.
This is especially problematic when we talk about the risks of an accident, which requires systematic oversight to avoid. It would be so much cheaper and easier to just not make mistakes, right? So just don't screw up!
That must have been what the National Guard was thinking when they released the names, social security numbers, pay and more for the 155th Brigade Combat Team by accident. The data was accidentally posted to an un-secure SharePoint site.
Details of the breach are still unknown, but the National Guard believes it was done inadvertently when uploading files to a new computer system. I'm going to take the liberty of making the leap and saying that it had to be someone with administrative privileges who uploaded the database somewhere it shouldn't have.
