In the July/August 2013 issue of IEEE Security & Privacy, we published Susan Landau's analysis of the impact of Edward Snowden's initial leak of documents. As more files are revealed, we want to provide up-to-date analysis of what they mean to you, our readers. Accordingly, we're posting an in-depth follow-up to Landau's original article (http://doi.ieeecomputersociety.org/10.1109/MSP.2013.90), which we'll revise periodically as new information becomes public. Landau's in-depth analysis not only summarizes what we know but also offers references that might prove useful in helping you come to your own conclusions about the leaks' import and impact.
