SRG-OS-000480-GPOS-00227
1 Rule
Windows Defender Firewall with Advanced Security must block unsolicited inbound connections when connected to a domain.
High Severity
A firewall provides a line of defense against attack. To be effective, it must be enabled and properly configured. Unsolicited inbound connections may be malicious attempts to gain access to a system. Unsolicited inbound connections, for which there is no rule allowing the connection, will be blocked in the domain.

1 Rule
Windows Defender Firewall with Advanced Security must allow outbound connections, unless a rule explicitly blocks the connection when connected to a domain.
Medium Severity
A firewall provides a line of defense against attack. To be effective, it must be enabled and properly configured. Outbound connections are allowed in the domain, unless a rule explicitly blocks the connection. This allows normal outbound communication, which could be restricted as necessary with additional rules.
SRG-OS-000327-GPOS-00127
1 Rule
Windows Defender Firewall with Advanced Security log size must be configured for domain connections.
Low Severity
A firewall provides a line of defense against attack. To be effective, it must be enabled and properly configured. The firewall log file size for a domain connection will be set to ensure enough capacity is allocated for audit data.
SRG-OS-000327-GPOS-00127
1 Rule
Windows Defender Firewall with Advanced Security must log dropped packets when connected to a domain.
Low Severity
