The US' National Security Agency isn't as united as it looks at first glance. Its intelligence gathering division (the one that conducts mass surveillance and hacking) and cyberdefense groups are largely separate. And that creates real problems -- among other issues, the intel group might be exploiting security flaws that the defensive team doesn't even know about, leaving critical systems open to attack. Those walls are about to come down, however. The NSA is poised to unveil a reorganization that will merge its offensive and defensive capabilities, helping them coordinate the fight against digital threats.
