CISA has actually regularly recommended employers to patch their VPNs, reinforce existing security and also implement multifactor authentication, as several employees continue to visit to company networks from their homes during the pandemic. "COVID-19 isn't vanishing anytime quickly, and we won't be going back to in-person verification for a lengthy time," Device 221B's Nixon said.
