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.

Trump tightens screws on ByteDance to sell Tiktok

President Trump added more pressure Friday night on China-based TikTok parent ByteDance to exit the U.S., ordering it to divest all assets related to the U.S. operation of TikTok within 90 days.

Between the lines: The order means ByteDance must be wholly disentangled from TikTok in the U.S. by November. Trump had previously ordered TikTok banned if ByteDance hadn't struck a deal within 45 days. The new order likely means ByteDance has just another 45 days after that to fully close the deal, one White House source told Axios.

In her first sit-down interview since being named Joe Biden's running mate, Sen. Kamala Harris talked about what she'll do to fight for women if elected VP, and how the Democrats are thinking about voter turnout strategies ahead of November.

What they're saying: "In a Biden-Harris administration women are going to be a priority, understanding that women have many priorities and all of them must be acknowledged," Harris told The 19th*'s Errin Haines-Whack.
