The DHS Daily Open Source Infrastructure Report is collected each
   business day as a summary of open-source published information
   concerning significant critical infrastructure issues. Each Daily
   Report is divided by the critical infrastructure sectors and key assets
   defined in the National Infrastructure Protection Plan.

   800 Daily Reports from DHS gathered so far, with FOIA requests pending
   for more.
   They'll be uploaded individually as soon as the new batch of
   sub-collections are created (hooray backlog)
   Enjoy!
