The dark web essentially refers to that portion of the web that is not easily publicly accessible. The dark web actually constitutes about 90% of the Internet. As much as we all see it as large, the vast majority of the Internet—the dark web—is everything from personalized systems to encoded or encrypted channels that are used.
In terms of how it helps in organization, our researchers found that at this point, terrorists have not been making extensive use of the dark web. That seems to be partly because the encryption software we have available, even commercially right now, is becoming increasingly difficult to crack and much of their communication is actually meant to be public. They're trying to recruit. They're trying to get their cause out there.
In terms of how they're communicating privately, that's a different issue. In terms of wanting to organize, our researchers found that, in fact, the dark web is not a significant element of that.
