NSA And The World Internet Traffic

In a document (PDF) on the nsa.gov website, the National Security Agency (NSA) said that the internet carries 1,826 Petabytes of information per day, and that its activity "touches" 1.6 percent of that data — approximately 29 petabytes, or 29 million gigabytes, of data each day. Of that number, the agency says 0.025 percent is selected for review.

Under its Business Records FISA (BR FISA) program, the agency is able to gain access to telephone metadata from US telcos that includes "called and calling telephone numbers and the date, time, and duration of the call — but no user identification, content, or cell site locational data".

The US agency said it partners with 30 different nations, and is prohibited from using its partner agencies to do work that the NSA itself would find illegal.

"These partnerships are an important part of the US and allied defence against terrorists, cyberthreat actors, and others who threaten our individual and collective security.

"Both parties to these relationships benefit."

The document was created to "address inaccuracies that have appeared in the media" and provide a level of transparency for the agency without endangering sources, methods, or national security.
