外部ユーザー認証(CLI手順)
概要
この設定では、ドメインログインと同じユーザー名とパスワードを使用したり、ファイアウォール管理者とやり取りすることなく資格情報を変更または回復できるため、より安全です。また、パスワードを頻繁に変更する必要があるため、管理者のワークロードも軽減されます。この設定をユーザ認証に使用することをお勧めします。
図1に示すように、インターフェイス、ゾーン、セキュリティポリシーを含むSRXシリーズファイアウォールの基本的な設定が完了していることを前提としています。
図1:トポロジー
前提条件については、「 Juniper Secure Connectのシステム要件」を参照してください。
SRXシリーズファイアウォールが、デフォルトのシステム生成証明書ではなく、署名付き証明書または自己署名証明書のいずれかを使用していることを確認する必要があります。Juniper Secure Connectの設定を開始する前に、以下のコマンドを実行して証明書をSRXシリーズファイアウォールにバインドする必要があります。
user@host# set system services web-management https pki-local-certificate <cert_name>
次に例を示します。
user@host# set system services web-management https pki-local-certificate SRX_Certificate
ここで、 SRX_Certificate 証明書はCAまたは自己署名証明書から取得されます。
CLIクイックコンフィグレーション
この例をSRXシリーズファイアウォールで迅速に構成するには、以下のコマンドをコピーしてテキストファイルに貼り付け、改行を削除して、ネットワーク構成に合わせて必要な詳細を変更し、[edit]階層レベルのCLIにコマンドをコピー&ペーストします。
