Companies use cyberdefense to limit damage

Disclosures last week about network intrusions at the New York Times and the Federal Reserve demonstrate that some companies have begun taking progressive steps to detect – and limit damage – from persistent cyberintruders. Thieves and spies are hacking into company networks as intensively as ever. But some large organizations are starting to limit the damage they can do, once inside. Information about successful defense strategies are being more widely shared for the greater good. "If you stop the bad actor from taking action on his or her objective, you win," says Steve Adegbite, director of cybersecurity at defense giant Lockheed Martin.
