Deputy National Security Adviser Anne Neuberger offers an update on the investigation into the SolarWinds supply chain attack. She says the Biden administration is preparing “executive action” to address security shortcomings that have come to light. Security experts say the Biden White House could enact several measures to address the cybersecurity concerns stemming from this hacking incident. One expert says the administration should change the structure of federal agencies and have department CISOs report directly to the secretary. Another expert says it should also call for the implementation of threat hunting across federal networks to better detect security flaws.”]
