The NSA leaks perpetrated by Edward Snowden will easily go down as one of the biggest revelations of the year, if not the decade. But the episode also raises new questions about the risk that insiders pose to government and corporate cybersecurity, in spite of the attention lavished on foreign hackers.
Snowden’s case is unique in that it uncovered a previously unknown surveillance apparatus that’s massive in size and scope. It’s not unique, however, in the way the whistleblower did his deed. Two-thirds of all reported data breaches involve internal actors wittingly or unwittingly bringing sensitive information to outsiders, according to industry analysts.
