More on D&D

a. Have Denial and Deception become obsolete in the face of modern intelligence gathering methods? No in fact I believe Denial and Deception efforts have become more important than ever now that the face of warfare has turned more towards guerilla/counterinsurgency type warfare vs traditional conventional tactics. This ups the ante and skill level required to successfully execute D&D efforts, in my opinion 

b. Are new intelligence gathering capabilities still being defeated by adaptations of classic Denial and Deception methods? In some cases, yes. One situation that comes to mind quickly is the Taliban/AQ forces. They are a vastly more primitive force, technologically speaking, but employ many ways of passing information and disseminating false intelligence aka showing the false and hiding the real. While in most cases they are defeated, they have obviously done a very good job of hiding UBL from us. This of course would be achieved through Denial and Deception tactics. 

c. Have we witnessed the appearance of new Denial and Deception techniques? Yes, and one field this is particularly true in is Information/Cyber Warfare. Viruses, false data banks, etc are being developed and upgraded on a constant basis. 

d. Do new techniques actually represent adaptations of old techniques, and do they still succeed. Yes, on a general level I believe so. The concepts of D&D remain the same regardless of time period. Thus, it could be argued that almost any new technique is actually a representation of an older technique. 

e. How can Denial and Deception efforts still succeed with so much known about them? Denial and Deception will always be a powerful ally for those who know how to use them. The human condition remains the same over time and therefore the same traits that cause people to fall for D&D tactics in the past will cause them to fall for them in the future. 

f. What areas besides military conflict do we see Denial and Deception being employed in? One area Denial and deception has become prevalent in is in the corporate world. The field of Competitive Intelligence has become relatively large and is growing at a very high rate. Companies have trade secrets and confidential information to protect and often employ methods to protect said data.
