Will the US be able to withstand cyber attacks on critical infrastructure?

The US Cybersecurity and Infrastructure Security Agency was set up in 2018 to help protect America's critical infrastructure.

It might sound like a technical term, but CISA chief Jen Easterly explains that critical infrastructure is how we get water, power, gas — even food at the grocery store. And 80% of it is operated by the private sector.

So, how does the agency help businesses defend themselves from hackers?

"In cybersecurity, the federal government is just a partner ... so we all have to work together to drive down risk to the nation," Jen Easterly tells Ian Bremmer on GZERO World.
