James Clapper, the Director of National Intelligence, has warned in his opening statement on the worldwide threat assessment before the Senate Armed Services Committee that cyber-attacks against  the US are increasing in frequency, scale, sophistication and severity of impact. He further stated that the US has been living with “a constant barrage” of cyber-attacks for some time. James Clapper concluded that this trend is set to continue and that the methods of attack, the systems targeted and the victims are continuing to expand in diversity and intensity.
