Case in point: the current illegal invasion of Ukraine, which has involved a horrible and bloody ground invasion and bombing campaign. Conflict has also occurred in cyberspace, as Kremlin-sponsored groups have deployed at least six destructive instances of
wiper malware against Ukrainian organizations and infrastructure. And according to Western governments' cybersecurity agencies, Putin's goons are looking to
expand their cyberattacks to US and its allies' critical infrastructure.
While battlegrounds used to be land, air, and sea, "now it's certainly space and cyberspace," Nakasone said. "And if you think about space and cyberspace, it's no longer the purview of any one nation, any one government, but a multitude of actors, including the commercial sector."
Quickly marshalling defenses against both cyber and physical threats also requires tools like big data, AI and machine learning, he added.
"In the environment that we are today, we no longer can rely on forward operating bases' ability to provide ground centers, or the ability to use airborne intelligence surveillance and reconnaissance," Nakasone opined.
"We will rely on cyber operations and space for most of our intelligence collection and critical key insights of our adversaries."
