PCI Compliance for Palo Alto Networks 用の Sumo Logic アプリケーションのログ収集を設定する手順。

このページでは、PCI Compliance for Palo Alto Networks アプリケーションのログを収集する方法を説明します。

ログ タイプ

PCI Compliance for Palo Alto Networks アプリケーションでの parse は、PAN-OS Syslog 統合に基づきます (「PAN-OS Syslog Integration (PAN-OS Syslog 統合)」を参照)。 

前提条件/要件

Collector および Source の設定

このステップでは、Installed Collector と、Palo Alto Networks デバイスからログおよびイベントを受信する Syslog サーバとして機能する Syslog Source を設定します。

  1. InstalledCollector の設定
  2. Syslog Source を Installed Collector に追加します。
    1. Name (名前): (必須) 名前は必須です。
    2. Description (説明): 省略可能。
    3. Protocol (プロトコル): UDP または TCP。  Syslog モニタリング用に Palo Alto Networks で設定したプロトコルを選択します。
    4. Port (ポート): ポート番号。Syslog モニタリング用に Palo Alto Networks で設定したポートを選択します。
    5. Source Category: (必須) [Source Category] メタデータ フィールドは、Source を整理してラベル付けするための基本的な構成要素です。詳細については、「ベスト プラクティス」を参照してください。
    6. [Save (保存)] をクリックします。
