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.

Biden will reverse Trump's attempt to lift COVID related travel restrictions

The incoming Biden administration will reverse President Trump's last-minute order to lift COVID-19 related travel restrictions, Jen Psaki, the incoming White House press secretary, tweeted.

Why it matters: President Trump ordered entry bans lifted for travelers from the U.K., Ireland, Brazil and much of Europe to go into effect Jan. 26, but the Biden administration will "strengthen public health measures around international travel in order to further mitigate the spread of COVID-19," Jen Psaki said. Biden will be inaugurated on Wednesday, Jan. 20 and Trump will no longer be president by the time the order is set to go into effect.

Dominion sends cease and desist letter to My Pillow CEO Mike Lindell

Dominion Voting Systems on Monday sent a cease and desist letter to My Pillow CEO Mike Lindell over his spread of misinformation related to the 2020 election.

Why it matters: Trump and several of his allies have pushed false conspiracy theories about the company, leading Dominion to take legal action. It's suing pro-Trump lawyer Sidney Powell for defamation and $1.3 billion in damages, and a Dominion employee has sued Trump himself, OANN and Newsmax.

Episode 5: The secret CIA plan

Beginning on election night 2020 and continuing through his final days in office, Donald Trump unraveled and dragged America with him, to the point that his followers sacked the U.S. Capitol with two weeks left in his term. This Axios series takes you inside the collapse of a president.

Episode 5: Trump vs. Gina — The president becomes increasingly rash and devises a plan to tamper with the nation's intelligence command.

In his final weeks in office, after losing the election to Joe Biden, President Donald Trump embarked on a vengeful exit strategy that included a hasty and ill-thought-out plan to jam up CIA Director Gina Haspel by firing her top deputy and replacing him with a protege of Republican Congressman Devin Nunes.
