Public networks: these are unsafe network connections (cybercafé, open Wi-Fi access point, etc.).

Windows Firewall with advanced security features supports more detailed rules than earlier versions of Windows Firewall, including filtering based on:

  • Users and groups
  • Source and destination IP addresses
  • IP port number
  • ICMP settings
  • IPsec settings
  • Services


The advanced firewall allows you to filter the incoming and outgoing connections of a host according to its configuration
