(Washington Composite Electric) US President Bynden warned on Monday that the latest signs show that the Russian government may launch a network attack on the US infrastructure to retaliate against Western countries to impose sanctions on it due to Russia's invasion of Ukraine.Biden urged American companies to prepare for defense immediately.

Biden said in a statement that the U.S. government will continue to use all tools to prevent and disturb, and respond to the network attack on key infrastructure for the United States when necessary.

But he emphasized that the most critical infrastructure of the local area is owned and operated by private enterprises, and the government cannot force them to take specific network security measures.

He called on these companies to improve network security as soon as possible.

After the meeting with the US business leader after Bayeng, Russia has "very advanced network capabilities", and online attack is one of the "most likely use" strategies for Russian President Putin.

Bynden mentioned that he had warned Putin not to launch an online attack on the key infrastructure of the United States in the summit of the Geneva and Putin last year.Biden said: "If he will have a long conversation if he uses the Internet attack." He added: "The key is, he has the ability. He has not used it yet."

Newberg, the US National Security Vice Consultant, who is responsible for the Internet and emerging technologies, said that although Bayeng issued a warning, "the key infrastructure may not be attacked by the Internet."She pointed out that Biden's statement aims to urge all parties, especially key infrastructure operators to take action to strengthen network security.

Bloomberg pointed out that the White House's ability to protect key infrastructure is limited, because most of them are operated by private enterprises from dams and grids to water supply systems and food production.Industry and companies are different.

Lewis, director of the Strategic Technology Project of Strategic and International Research Center, said that Russia is unlikely to launch large -scale Internet attacks to avoid being retaliated by the United States, but Russia has a slow frustration of Ukraine's aggression.It will prompt the Kremlin to launch a smaller -scale net attack or extortion software attack.
