Network Security Postures
- Windows Defender Firewall has different security postures for different networks.
- It recognizes when a computer is on a public versus a private network.
- Private networks automatically allow other devices on the local network to connect for file or application sharing.
- Public networks change the security posture to prevent unauthorized access to resources.
- Windows Defender Firewall allows customization of public and private configurations.
Customization Options
