CIO Dana Deasy lays out the department's plan in response to Sen. Ron Wyden, who raised concerna about the security of DOD's many public-facing sites.

"I think that line has to be drawn, and we have to respond, and they need to pay a fairly significant price for what they're doing.”

A Chinese intelligence agency was able to successfully hack into a Navy contractor around February, stealing more than a half terabyte worth of highly sensitive documents.

The highest bounty was $5,000 paid out eight times.

The House of Representatives on Thursday overwhelmingly passed a defense policy bill with several cybersecurity measures aimed at better securing Pentagon networks. The bill seeks closer collaboration between the departments of Defense and Homeland Security in defending against hackers, asks for quick notification of data breaches of military personnel, and continues to crack down on foreign-made telecom products that are deemed security threats.

Wyden warns that neglecting the security of public-facing DOD websites could embolden cybercriminals and state-backed hackers.
