AI hunters for your computer intruders

Humans are no longer sufficient to police cyber attackers, experts tell Axios, and machines must move in to find them.

Quick take: "High walls and bigger moats" are obsolete in computer security, says Mark Testoni, CEO of NS2, the U.S. arm of German software giant SAP. Instead, people, governments and organizations housing sensitive material on their computers should "presume that intruders are already inside," he tells Axios.

  • We have seen over the last few years that determined attackers can penetrate even agencies with ostensibly the greatest protections, like the U.S. National Security Agency.
  • AI firms, Testoni said, must develop tools to find and isolate intruders presumed to be lying inside sensitive systems, whether active or dormant.

What's next: Geopolitical players — the U.S., Russia, China, North Korea, Iran and Israel, to name a few — are in overdrive developing their cyber capabilities. One of the next frontiers for AI is to develop ways to predict the source and targets of future attacks.

The U.S. suburbs are hot again

The talk around the world is about the rise of the city. But in the U.S., suburbanization is accelerating, according to new Census data released today.

Data: Census Bureau, analysis by Jed Kolko at Indeed.com; Chart: Axios Visuals

What's happening: Since about 2011, the growth of the urban counties of large cities has been sliding. Population growth in their higher-density suburbs has been falling since 2015 as well. But, as you see in the chart above, lower-density suburbs had the highest growth among all places, and exurbs and small towns have also been on the rise, according to an analysis of the data by Jed Kolko, chief economist at Indeed.

Sen. Cortez Masto: Safety is a key component of smart cities

Nevada Sen. Catherine Cortez Masto said safety has to be a key component of new technological advances as they transform U.S. cities.

Why it matters: Citizens' safety is a primary concern as technology marches toward replacing humans in a number of different functions in our cities, such as driving. New attention has been drawn to this this issue by this week's fatal crash involving an autonomous vehicle in Arizona.
