ICS-CERT Removed AV Update Publication

Sometime today (I’m pretty sure) the DHS ICS-CERT removed mention of their “Recommended Practice: Updating Antivirus in an Industrial Control System” from both their ICS-CERT landing page and their Recommended Practices page. The previously provided link to this document (that was originally published on January 8^th, 2018) now returns an “Access denied. You are not authorized to access this page” message.

I have a copy of the web page from Friday morning that shows the notice for this document on the landing page. I am pretty sure that it was there on both Saturday and this morning when I check the web site. There is no indication that the item was removed, much less an explanation for why. I did not see anything in the document that should have caused any problems and the same information is still available in the Sept-October NCCIC/ICS-CERT Monitor.

It will be interesting to see if this comes back….

BTW: For some reason I never saved a copy of the publication. Could someone please send me a copy? NOTE (added 2-7-18 09:04 EST): I now have a copy from a reader. Thanks to all of those who have offered to provide me a copy.
