WASHINGTON (AP) — The Whited House on Wednesday offered to help U.S. businesses protect their computer systems from cyberattacks that President Barack Obama called ‘‘one the gravest national security dangers that the United States faces.’’
Administration officials warned during an event at the White House that an attack on critical sectors of the U.S. economy could put the entire country at risk.
‘‘It boils down to this — in cybersecurity, the more systems we secure, the more secure we all are,’’ said Homeland Security Secretary Jeh Johnson. ‘‘We are all connected online and a vulnerability in one place can cause a problem in many other places.’’
The administration released a 39-page guide urging vital industries like transportation, financial, health care and energy to assess their risk and take action to close gaps. The Homeland Security Department also launched a voluntary program for businesses to get help at no cost from its cybersecurity experts about ways to counter threats.
