Enable Network Firewall & Secure Network

A network firewall is a type of network security device that can be either hardware- or software-based. The firewall monitors all the incoming or outgoing traffic and also blocks unknown security rules. This will prevent or set a limit on illegal access for private access. To access the firewall, click on Start > Settings > Update & Security > Windows Security and turn on the Firewall and Network Protection toggle.

The Microsoft Defender firewall shows three options for the following network types: domain networks (Workplace), private networks (Discoverable), and public networks (Non – Discoverable).

  • Run the Network and Internet Troubleshooter to resolve the network issues.
  • Allow notifications when the firewall blocks something.

  • With advanced settings, you can check connection security and monitor logs.
