EAP-TLS認証を使用した証明書ベースの検証(CLI手順)
概要
この構成では、EAP-TLS 認証方法を使用してユーザー証明書を検証します。RADIUSサーバーを使用した外部ユーザー認証に引き続きユーザー名とパスワードを使用し、SRXシリーズファイアウォールから初期設定をダウンロードします。
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など、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。
公開キー基盤 (PKI) がバックエンド認証として構成されていることを確認します。この場合、CAのルート証明書を各クライアントにインストールし、ユーザー固有の証明書を各クライアントデバイスにインストールする必要があります。このシナリオでは、ローカル認証はサポートされないことに注意してください。
SRXシリーズファイアウォールは、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、次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>
例えば：
user@host# set system services web-management https pki-local-certificate SRX_Certificate
ここで、SRX_Certificate は自己署名証明書です。
CLIクイック構成
お使いのSRXシリーズファイアウォールでこの例を素早く設定するには、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、ネットワーク設定に合わせて必要な詳細を変更し、コマンドを[edit]階層レベルのCLIにコピー&ペーストしてください。
