There are dimensions to security in the 5G age that no one, including the experts, has quite figured out yet.

Why it matters: If you think today's cybersecurity landscape is treacherous, just wait.

The "Internet of Things" problem: Devices for automating your home favor low prices over strong security, making them easy picking for hackers.

  • People secure those devices today by buying additional products to monitor home-network traffic.
  • But with 5G, many more devices will bypass that network and connect directly to the internet.
  • The problem isn't one hacked toaster — it's millions of controllable hijacked gizmos
  • Hackers can network together legions of devices to flood servers with so much traffic that they collapse. A recent website outage spanning Twitter, Netflix and Etsy was caused by weakly secured web cameras.

Data overload: The growth in connected devices also means an unimaginable amount of data will now be stored with every consumer.

  • Expect enormous privacy controversies. Who knows what kinds of data a new universe of smart bathroom products will collect or sell to advertisers?
  • The data explosion will also demand a rapid increase in cloud security in industries that haven’t much needed it in the past.

Security concerns could limit 5G in rural areas, where smaller carriers operate at lower profit margins.

  • When these providers upgrade services, including potentially providing 5G, they sometimes use cheaper Chinese hardware from companies like ZTE and Huawei.
  • But the same providers rely on federal funding to buy equipment, which the FCC seems poised to pull, and the private carriers might not be ready to make up the difference.

Joe Biden's campaign released his 2019 tax returns on Tuesday, showing that he and his wife, Jill, paid nearly $300,000 in federal taxes last year.

Why it matters: The release, timed just hours before the first presidential debate, comes days after a bombshell New York Times report said that President Trump paid only $750 in federal taxes in 2016 and 2017. Biden's team is hoping to make the tax contrast a sticking point during their showdown.

NYC's coronavirus positivity rate spikes to highest since June

New York City's coronavirus positivity rate has ticked up to 3.25%, its highest since June, Mayor Bill de Blasio said at a news conference on Tuesday.

Why it matters: The jump — from 1.93% on Monday — came on the first day that public elementary classrooms reopened in the city after months of closures, but guidelines state that all public schools will have to shut if the citywide seven-day positivity rate stays above 3%.
