So far, no one has managed to seriously damage or disrupt our critical infrastructure networks. But foreign governments, criminal syndicates and lone individuals are probing our financial, energy and public safety systems every day. Last year, a water plant in Texas disconnected its control system from the Internet after a hacker posted pictures of the facility’s internal controls. More recently, hackers penetrated the networks of companies that operate our natural-gas pipelines. Computer systems in critical sectors of our economy—including the nuclear and chemical industries—are being increasingly targeted.
It doesn’t take much to imagine the consequences of a successful cyber attack. In a future conflict, an adversary unable to match our military supremacy on the battlefield might seek to exploit our computer vulnerabilities here at home. Taking down vital banking systems could trigger a financial crisis. The lack of clean water or functioning hospitals could spark a public health emergency. And as we’ve seen in past blackouts, the loss of electricity can bring businesses, cities and entire regions to a standstill.
This is the future we have to avoid. That’s why my administration has made cybersecurity a priority, including proposing legislation to strengthen our nation’s digital defenses. It’s why Congress must pass comprehensive cybersecurity legislation.
