Azure 防火牆診斷記錄 （舊版）
診斷記錄是原始Azure 防火牆記錄查詢，會以非結構化或自由格式的文字格式輸出記錄資料。
診斷記錄支援下列記錄類別：
- Azure 防火牆應用程式規則
- Azure 防火牆網路規則
- Azure 防火牆 DNS Proxy
應用程式規則記錄
應用程式規則記錄會儲存至儲存體帳戶、串流至事件中樞和/或傳送至 Azure 監視器記錄，但前提是您已針對每個Azure 防火牆啟用它。 符合其中一個已設定應用程式規則的新連線，都會產生已接受/拒絕連線的記錄。 資料會以 JSON 格式記錄，如下列範例所示：
Category: application rule logs.
Time: log timestamp.
Properties: currently contains the full message.
note: this field will be parsed to specific fields in the future, while maintaining backward compatibility with the existing properties field.
{
"category": "AzureFirewallApplicationRule",
"time": "2018-04-16T23:45:04.8295030Z",
"resourceId": "/SUBSCRIPTIONS/{subscriptionId}/RESOURCEGROUPS/{resourceGroupName}/PROVIDERS/MICROSOFT.NETWORK/AZUREFIREWALLS/{resourceName}",
"operationName": "AzureFirewallApplicationRuleLog",
"properties": {
"msg": "HTTPS request from 10.1.0.5:55640 to mydestination.com:443. Action: Allow. Rule Collection: collection1000. Rule: rule1002"
}
}
{
"category": "AzureFirewallApplicationRule",
"time": "2018-04-16T23:45:04.8295030Z",
"resourceId": "/SUBSCRIPTIONS/{subscriptionId}/RESOURCEGROUPS/{resourceGroupName}/PROVIDERS/MICROSOFT.NETWORK/AZUREFIREWALLS/{resourceName}",
"operationName": "AzureFirewallApplicationRuleLog",
"properties": {
"msg": "HTTPS request from 10.11.2.4:53344 to www.bing.com:443. Action: Allow. Rule Collection: ExampleRuleCollection. Rule: ExampleRule. Web Category: SearchEnginesAndPortals"
}
}
網路規則記錄
只有在您已針對每個Azure 防火牆啟用網路規則記錄時，才會將網路規則記錄儲存至儲存體帳戶、串流至事件中樞和/或傳送至 Azure 監視器記錄。 符合其中一個已設定網路規則的新連線，都會產生已接受/拒絕連線的記錄。 資料會以 JSON 格式記錄，如下列範例所示：
Category: network rule logs.
Time: log timestamp.
Properties: currently contains the full message.
note: this field will be parsed to specific fields in the future, while maintaining backward compatibility with the existing properties field.
{
"category": "AzureFirewallNetworkRule",
"time": "2018-06-14T23:44:11.0590400Z",
"resourceId": "/SUBSCRIPTIONS/{subscriptionId}/RESOURCEGROUPS/{resourceGroupName}/PROVIDERS/MICROSOFT.NETWORK/AZUREFIREWALLS/{resourceName}",
"operationName": "AzureFirewallNetworkRuleLog",
"properties": {
"msg": "TCP request from 111.35.136.173:12518 to 13.78.143.217:2323. Action: Deny"
}
}
DNS Proxy 記錄
DNS Proxy 記錄會儲存至儲存體帳戶、串流至事件中樞，以及/或只有在您已針對每個Azure 防火牆啟用它時，才會傳送至 Azure 監視器記錄。 此記錄會追蹤 DNS 訊息至使用 DNS Proxy 設定的 DNS 伺服器。 資料會以 JSON 格式記錄，如下列範例所示：
Category: DNS proxy logs.
Time: log timestamp.
Properties: currently contains the full message.
note: this field will be parsed to specific fields in the future, while maintaining backward compatibility with the existing properties field.
成功：

"category": "AzureFirewallDnsProxy",
"time": "2020-09-02T19:12:33.751Z",
"resourceId": "/SUBSCRIPTIONS/{subscriptionId}/RESOURCEGROUPS/{resourceGroupName}/PROVIDERS/MICROSOFT.NETWORK/AZUREFIREWALLS/{resourceName}",
"operationName": "AzureFirewallDnsProxyLog",
"properties": {
"msg": "DNS Request: 11.5.0.7:48197 – 15676 AAA IN md-l1l1pg5lcmkq.blob.core.windows.net. udp 55 false 512 NOERROR - 0 2.000301956s"

}
}
msg 格式：
[client’s IP address]:[client’s port] – [query ID] [type of the request] [class of the request] [name of the request] [protocol used] [request size in bytes] [EDNS0 DO (DNSSEC OK) bit set in the query] [EDNS0 buffer size advertised in the query] [response CODE] [response flags] [response size] [response duration]
儲存體
您有三個選項可用來儲存記錄：
- 儲存體帳戶 ：儲存體帳戶最適合用於記錄儲存較長期間，並視需要檢閱記錄。
- 事件中 樞：事件中樞是與其他安全性資訊和事件管理 （SEIM） 工具整合以取得資源警示的絕佳選項。
- Azure 監視器記錄 ：Azure 監視器記錄最適合用於應用程式的一般即時監視或查看趨勢。
