Take some time to read the article found in the link below. It brings out some good points from both sides of the interior/exterior argument. We have all seen the new research presented by UL/NIST and we should make it a point to educate ourselves. Not taking sides here, but I feel this is a decently neutral take on the situation. One idea repeated is the fact that none of the new tactics are new at all. We just now have the ability to test and gather data. Please take a look and don't get too hung up on the accolades of the author at the end bio!
