Our capabilities give us the power to change the narrative by making our networks more secure—and ensuring that cyberspace itself becomes a safer place for commerce, social interaction and the provision of public services. We want to take this opportunity to put these developments in historical context, and then explain why we as a nation must continue to build a cyberenterprise capable of guarding our critical infrastructure and population. We can and must do this while always protecting civil liberties, personal privacy and American values.
