# ASFF 中的 AwsNetworkFirewall 资源
以下是`AwsNetworkFirewall`资源 AWS 的安全调查结果格式 (ASFF) 语法的示例。
AWS Security Hub CSPM 将各种来源的发现标准化为 ASFF。有关 ASFF 的背景信息，请参阅 [AWS 安全调查结果格式 (ASFF)](securityhub-findings-format.md)。
## AwsNetworkFirewallFirewall
`AwsNetworkFirewallFirewall` 对象包含有关 AWS Network Firewall 防火墙的详细信息。
以下示例显示了`AwsNetworkFirewallFirewall`对象 AWS 的安全调查结果格式 (ASFF)。要查看 `AwsNetworkFirewallFirewall` 属性的描述，请参阅 *AWS Security Hub API 参考*中的 [AwsNetworkFirewallFirewallDetails](https://docs.aws.amazon.com/securityhub/1.0/APIReference/API_AwsNetworkFirewallFirewallDetails.html)。
**示例**
```
"AwsNetworkFirewallFirewall": {
"DeleteProtection": false,
"FirewallArn": "arn:aws:network-firewall:us-east-1:024665936331:firewall/testfirewall",
"FirewallPolicyArn": "arn:aws:network-firewall:us-east-1:444455556666:firewall-policy/InitialFirewall",
"FirewallId": "dea7d8e9-ae38-4a8a-b022-672a830a99fa",
"FirewallName": "testfirewall",
"FirewallPolicyChangeProtection": false,
"SubnetChangeProtection": false,
"SubnetMappings": [
{
"SubnetId": "subnet-0183481095e588cdc"
},
{
"SubnetId": "subnet-01f518fad1b1c90b0"
}
],
"VpcId": "vpc-40e83c38"
}
```
## AwsNetworkFirewallFirewallPolicy
`AwsNetworkFirewallFirewallPolicy` 对象提供有关防火墙策略的详细信息。防火墙策略定义网络防火墙的行为。
以下示例显示了`AwsNetworkFirewallFirewallPolicy`对象 AWS 的安全调查结果格式 (ASFF)。要查看 `AwsNetworkFirewallFirewallPolicy` 属性的描述，请参阅 *AWS Security Hub API 参考*中的 [AwsNetworkFirewallFirewallPolicyDetails](https://docs.aws.amazon.com/securityhub/1.0/APIReference/API_AwsNetworkFirewallFirewallPolicyDetails.html)。
**示例**
```
"AwsNetworkFirewallFirewallPolicy": {
"FirewallPolicy": {
"StatefulRuleGroupReferences": [
{
"ResourceArn": "arn:aws:network-firewall:us-east-1:444455556666:stateful-rulegroup/PatchesOnly"
}
],

"FirewallPolicyId": "9ceeda22-6050-4048-a0ca-50ce47f0cc65",
"FirewallPolicyName": "InitialFirewall",
"Description": "Initial firewall"
}
```
## AwsNetworkFirewallRuleGroup
`AwsNetworkFirewallRuleGroup` 对象提供有关 AWS Network Firewall 规则组的详细信息。规则组用于检查和控制网络流量。无状态规则组适用于各个数据包。有状态规则组适用于其流量上下文中的数据包。
规则组在防火墙策略中引用。
以下示例显示了`AwsNetworkFirewallRuleGroup`对象 AWS 的安全调查结果格式 (ASFF)。要查看 `AwsNetworkFirewallRuleGroup` 属性的描述，请参阅 *AWS Security Hub API 参考*中的 [AwsNetworkFirewallRuleGroupDetails](https://docs.aws.amazon.com/securityhub/1.0/APIReference/API_AwsNetworkFirewallRuleGroupDetails.html)。
**示例——无状态规则组**
```

"Sources": [
{
"AddressDefinition": "198.51.100.0/24"
}
]
}
}
}
]
}
}
}
}
```
**示例——有状态规则组**
```
