Lawmakers will push to pass a mandatory data breach notification law following the high-profile attack last year on SolarWinds, the network management and IT security company.

The compromise of the SolarWinds Orion IT monitoring and management software package, suspected to be the work of hackers affiliated with the Russian government, has compromised about 100 companies and nine U.S. agencies, including the departments of Homeland Security, State, and Justice. Up to 17,000 SolarWinds customers downloaded the malware.
