インシデント対応チームは、法執行機関と協力して、アクティブな Web サーバーの侵害を調査しています。一定期間、サーバーを稼働させ、補償制御を実装することが決定されました。Web サービスは、リバース プロキシ経由でインターネットからアクセスでき、データベース サーバーに接続する必要があります。次の補償制御のどれが、他の要件を満たしながら敵対者を封じ込めるのに役立ちますか? (2 つ選択してください)。
正解:B,D
Deploying EDR on the web server and the database server to reduce the adversaries capabilities and using micro segmentation to restrict connectivity to/from the web and database servers are two compensating controls that will help contain the adversary while meeting the other requirements. A compensating control is a security measure that is implemented to mitigate the risk of a vulnerability or an attack when the primary control is not feasible or effective. EDR stands for Endpoint Detection and Response, which is a tool that monitors endpoints for malicious activity and provides automated or manual response capabilities. EDR can help contain the adversary by detecting and blocking their actions, such as data exfiltration, lateral movement, privilege escalation, or command execution. Micro segmentation is a technique that divides a network into smaller segments based on policies and rules, and applies granular access controls to each segment. Micro segmentation can help contain the adversary by isolating the web and database servers from other parts of the network, and limiting the traffic that can flow between them.
