Dare to Share" - August21 Aug speech by Dr. Central to all of this is collaboration. I always use the word collaborations rather than cooperation. Cooperation is something we make people do: Play nice in the sandbox.

You will come to this coordination meeting. Collaboration must be something people are excited to do; do without thinking about; do in ways that are invisible or transparent; do because they recognize it leads to better insights, and more timely responses. It might; it might not.

Instead of relying on those who can make it to the meeting or happen to be in town at critical junctions to shape it, we will engage any who are knowledgeable and let the Wikipedia process operate.

We might have to tweak it. We might want to run the regular process in parallel, as we are running in parallel a number of analytic efforts where we give the same questions to an outside group using open sources as we give the community to work using all of our classified data.

Exactly how much better, and on what questions, does classified information yield better insights than what we can produce using unclassified information? There are people that describe this as one of the scariest innovations that I have launched. How many of you have supermarket discount cards?

Do you know how much of your privacy you are giving up with those cards? You are giving it all up. They know everything that you buy down last match, whatever.

The stuff you get in your mailbox is very much determined by what you put when you scan your card. You know, they knew for example that there was a super-high correlation between the purchase of beer and diapers. Now, that is not because men are all babies, as all of the women here know.

I have to change him; you go buy them. And honey goes to the store, and he has to buy diapers, and what else does he buy? At NSA there is this habit in analysts of only looking at highly classified information on highly classified networks.

I would take it and show it to them. And they were very busy. They were just extremely busy, and it was not comfortable and familiar to them to look at this non-intel, non-top-secret stuff. It was not easy. It was not simple. It was not in their comfort zone.

I interviewed over a three-week period analysts in Baghdad when I was out there. And that was very difficult, by the way. This is a type of psychology that has to do with observing organisms in their natural habitat without disturbing them.

Securities of OSI

So these organisms were MI analysts in Baghdad. So I put on a uniform and I sat there at the terminal and did what they did, and I wrote reports and, you know, did stuff like that. Well, did you know that you have a lot of single sign-on capability in federated query with Pathfinder?

And they said, ahh! So what we did was we came up with this federated query system. We called it Oggle spand the letters may have kind of looked like Google.

No copyright or trademark infringement the lawyers tell me. But the fact of the matter is, they already new how to do it.OSI Seven Layers Model Explained with Examples This tutorial explains OSI Seven Layer model in details with examples. Learn how Seven Layers OSI model works in computer network including functions and protocols involved in each layer of OSI Model (Application, Presentation, Session, Transportation, Network, Data link and physical layer).

Introduction. This paper serves as an attempt to broadly but briefly catalogue the list of serious issues that are unresolved with the concept of Public Key Infrastructure [] [].The catalogue was started in , and has grown as new issues and new references to those issues have come to light.

Some basic security functionality can also be set up by filtering traffic using layer 3 addressing on routers or other similar devices. Layer 4 – The Transport Layer Layer 4,the transport layer of the OSI model,offers end-to-end communication between end devices through a network.

AET Internal Combustion Engine Theory and Servicing. This is a theory/laboratory course designed to introduce the student to basic heat engine types, their physical configurations and various engine operating cycles. OSI (Open System Interconnection) Model: Application Presentation Session Transport Network Data Link Physical Addressing and routing On a Wide Area Network, the routing of data is done mainly using TCP/IP (Transmission Control protocol/Internet Protocol).

The OSI, or Open System Interconnection, model defines a networking framework for implementing protocols in seven layers.

Control is passed from one layer to the next, starting at the application layer in one station, and proceeding to the bottom layer, over the channel to .
