Part 2 of this two-part episode looks at the flip side of criminal hacks  —the defense. Law enforcement and private security teams work diligently to defend against cyber threats. And they often work better together. We speak with Nick Rossmann, former head of IBM X-Force with a background in both the CIA and FBI. He explains how threat intelligence is evolving to keep pace with the booming cybercrime industry, and how the dark side of the industry is becoming a full-service economy.
