Until now, starting up a “cyber attack team” has been a relatively inexpensive endeavor when compared to establishing an actual physical force. DoD is now determined to increase the costs for malicious actors to perform cyber attacks while making them less successful (emphasis added):

Cyber changes rapidly, according to Henry Muller, director of the U.S. Army Communications-Electronics Research, Development and Engineering Center (CERDEC). “In less than two decades, cyberspace has radically transformed how the Army operates and wages war,” he said. “Unlike the physical domains, cyberspace will continue to grow and is projected to reach over 100 billion connected devices within just the next 10 years.”

Bharat Doshi, CERDEC’s senior cybersecurity research scientist, noted that many different processes, policies and technologies can be used to make it costlier for adversaries to mount a successful attack. “Since the operational discipline and hygiene are critical first lines of defense, basic but persistent improvements in these areas will make it more expensive for an adversary to succeed,” he said.

CERDEC is currently researching several promising technologies, Doshi said. “One general class of technologies involves obfuscation, which prevents the adversary from getting valuable information even if they are able to observe our systems. Encryption of data at rest, data in transit and data in processing provides one way of obfuscation.”
