The Department of Homeland Security publishes an ~daily Open Source Infrastructure Report which contains a summary of open-source published information concerning significant critical infrastructure issues (and not just IT security related). You can subscribe to e-mail alerts to be notified when they are available (they do not publish on weekends or holidays) and are in PDF format. While the information is sometimes a bit dated (by a day or two), I have found interesting/useful data in almost every report. It definitely belongs on your quick-scan list for the day.

There is, unfortunately, no "permalink" to the latest published report and - while PDF is an acceptable means of distribution - it means having a PDF viewer installed or available, which may not be the case on all systems.

I came up with a solution to both of these issues by creating a bookmarklet that always links to the current day's report (so it will not work if there is no report for today or the report has not uploaded yet) and turns the link into a Google PDF Viewer document, so you can see it in virtually any browser without the need for a PDF plug-in and without having to download it to your local system.

The bookmarklet has been tested with IE 7, Safari 4 & Firefox 3.5 and you just need to drag the link below to your bookmarks bar. Drop me a note in the comments if you encounter any errors or have any enhancements to it.
