Hat tip to IBM physical security pro Clayton Hollister for pointing out this great resource: the DHS Daily Open Source Infrastructure Report ... pronounceable acronym: DOSsIeR.
Simply click the day you want to check out, select "fast jump" to energy and you'll get DHS' account of some of the most significant (not too sensitive) electricity outages in the USA. Or pick another sector like nuclear, chemical or water to see how they're faring.
I think you'll agree this is pretty interesting if you haven't seen it before. Sure is a heck of a lot info and incidents to manage. Good thing DHS has 200,000 employees. Holy cow, that's huge. They're almost half the size of IBM!
