Cisco Secure Analytics で Command & Control の過検知を抑制したい

08-01-2025
Cisco Secure Analytics (旧Stealthwatch)を使用しています。 最近、Command & Control のフローを検知するようになりまして、慌ててフローの詳細を確認したところ、「Suspect Long Flow」というイベントとして検知されており、更に関連フローを調べたところ、アプリケーションは MS-Teams などのマイクロソフト製品として識別されていました。宛先IPアドレスは日本・インド・ヨーロッパなど様々でしたが、いずれも悪意あるIPアドレスではありま...
