Katie intends to enable Chrome to pass through the Windows Defender firewall. What kind of modification does she need to make to the firewall rule to allow this?

Windows Defender Firewall functions on a per-application basis and can filter traffic based on whether the system is operating on a trusted private network or a public network. To permit Chrome through the firewall, Katie should add Chrome to the list of allowed applications in the firewall settings. This will enable Chrome to transmit traffic without the requirement of specifying ports or protocols.
