Protecting America’s cybersecurity demands showing our teeth

### Executive Summary — This opinion piece from Cyberspace Solarium Commission officials warns that the United States remains highly vulnerable to cyberattacks against critical infrastructure and argues for a dual approach: bolster defensive measures (modernize legacy systems, fill cybersecurity roles, test resiliency such as Section 1517) and develop visible, credible offensive cyber deterrence (including possible strategic declassification and public attribution) so adversaries are deterred from harming U.S. systems; it also urges civilian preparedness to mitigate impacts of successful attacks.
