AWSだ! Google Cloudだ! Azureだ! 認証連携だ！

昨今は、さまざまな要因から、複数のクラウド（IaaS）プロバイダーを活用することが多くなりました。例えば、サービスのワークロードはAWSだが、データ分析はGoogle CloudのBigQueryを使うなどです。異なるプロバイダー間でのリソースにアクセスするには、認証が必要であり、シークレットを安全に発行・交換する必要があります。クラウドプロバイダーが動的に発行する等さまざまな方式がありますが、システムの制限や運用によっては安全なシークレットの取り扱いのために、慎重な技術設計が必要になる場合もあります。

今回は、LayerXにおける要件パターン、脅威モデリングに基づく判断と実装方法を紹介することで、「どこまで気をつけるべきか？」「何を想定すべきか？」といった実務に対して参考いただけると嬉しいです
