On Thursday, the White House will meet with leaders from key tech companies, including Alphabet's Google, Apple, and Amazon.com, to address software security following three major cyberattacks in the United States last year.

After the revelation of a security vulnerability in open-source software called Log4j, which enterprises all over the world use to log data in their apps, White House National Security Advisor Jake Sullivan wrote a letter to CEOs of digital companies in December.

Sullivan wrote in the letter that open source software is widely used and maintained by volunteers, and that it is a "critical national security priority."

The White House said in a statement that the meeting, which will be chaired by Anne Neuberger, deputy national security advisor for cyber and emerging technology, will focus on concerns about open-source software security and how it might be improved.

IBM, Microsoft, Meta Platforms, which owns Facebook, and Oracle will all be in attendance at the summit. There will also be representatives from the Department of Homeland Security, the Department of Defense, and the Department of Commerce in attendance.

Following three significant breaches last year, which exposed thousands of information stored by companies and government agencies to hackers, the Biden administration has made cybersecurity a high priority.

One attack, which the US government believes was likely perpetrated by Russia, exposed SolarWinds software and offered hackers access to tens of thousands of businesses and government agencies that used the company's products. Emails from the US Treasury, Justice, and Commerce departments, as well as other agencies, were accessed by the hackers.

The administration issued an executive order last year, creating a review board and new software standards for government organizations, in response to the increasing frequency and severity of such attacks.
