Adversaries have heavily invested in cyberspace operations and capabilities. As such, cyber operations, cybersecurity and information operations are increasingly important to the joint force, said the commander of U.S. Cyber Command, who's also the director of the National Security Agency.
"The scope of what we need to defend and protect has dramatically expanded," Army Gen. Paul M. Nakasone said today during a virtual address to the U.S Naval Institute and Armed Forces Communications and Electronics Association's WEST Conference.
The Defense Department's information network is composed of 15,000 sub-networks, 3 million users, 4 million computers, 180,000 mobility devices and 605 million website requests a day, he said.
"We used to think about cyberspace as merely the need to protect these computer networks. And while it's a good place to start, the attack surface is much broader," Nakasone said.
For example, protecting weapons systems is a related but distinct challenge compared to networks, he said. They require software updates and patches. In the case of the Navy, they're onboard ships that don't return to port for months at a time, making it even more challenging to provide timely updates.
Another challenge with weapons systems is ensuring that cybersecurity considerations are implemented in the earliest phases of the acquisition cycle, he said.
Protecting DOD's data is also a major challenge, he said.
"We learned how to work closely with U.S. Special Operations Command, both to support their efforts against kinetic targets and to leverage their capabilities against virtual ones," he said.
Having a skilled and motivated workforce is also critically important, he said. They need to have the right training and career paths and professional development opportunities, and the DOD must be open to their new ideas.
