Title: Incident Report 2009-049

The National Security Agency (NSA), the location for U.S. Communications Security, has released a series of documents titled "A History of U.S. Communications Security" over the years. The first volume, "A History of U.S. Communications Security, Volume I," was published in 1973 and was given the appeal number 2009-049-doc1. This was followed by the second volume, published in 1981, which was designated as 2009-049-doc2.

The most recent update to these documents occurred on December 17, 2015. The third volume in the series, while likely published since 1981, does not seem to have been publicly disclosed as of now. If it has been published, the author is believed to be David G. Boak.

Interestingly, these documents are not just static documents. They feature interactive elements, such as clickable table headers that allow for sorting by the clicked column header, enhancing their usability and accessibility.

It's worth noting that the appeal adjudication period at the NSA falls within the fiscal year. For the fiscal year 2015, this period spanned from October 1, 2014, to September 30, 2015.

These documents provide valuable insights into the evolution of U.S. Communications Security over the decades and are a testament to the NSA's commitment to transparency and record-keeping. As new volumes are released, the public will undoubtedly gain a deeper understanding of this crucial aspect of national security.
