Defense Secretary Leon Panetta told a Louisville, Ky. audience Thursday that the thought of a major cyberattack keeps him awake at night.
Panetta told the University of Louisville audience that the U.S. is growing in cyber expertise but agencies still suffer thousands of cyber attacks daily, the Defense Department reports.
Panetta said targets go beyond government and worries there will be technologies capable of crippling the power grid and financial systems.
Aside from a strong cyber defense system, Panetta said the U.S. needs to find a way to understand and estimate when possible cyberattacks are coming.
Panetta said his major fear is that all the necessary steps to protect the country haven’t been taken.
