How the SolarWinds breach became "one of the worst hacks ever to hit government agencies."

When the IT software company SolarWinds was breached in a cyber hack, cybersecurity firewalls across the United States were effectively slashed open. The widespread damage affected companies of every size and many U.S. government agencies. Since then, more information has bubbled up about the hack, its size, and the ramifications for information security. So what have we learned since we first discovered what happened and the astounding number of companies and agencies affected? What can we do to keep something like the SolarWinds hack from happening ever again? And on a national level, how is the U.S. responding? Dr. Pablo Molina, Chief Information Security Officer at Drexel University joins KYW Newsradio in Depth to talk about how the SolarWinds breach became "one of the worst hacks ever to hit government agencies," why the damage was so extensive, and what needs to happen next.
