デジタルフォレンジック調査において、調査員は組織のインフラストラクチャ内のサーバーや共有ドライブからデータを収集する任務を負います。調査員は、これらの中央ストレージから関連する電子証拠にアクセスし、取得することで調査を支援します。収集されるデータには、インシデントの範囲を把握するために必要なファイル、ユーザーログ、その他のシステムアーティファクトが含まれます。このシナリオにおいて、調査員はどのようなeDiscovery収集手法を採用していますか?
正解:A
Under the CHFI v11 objectives related to the eDiscovery process , investigators must understand and correctly apply various eDiscovery collection methodologies based on where data resides and how it is accessed. In this scenario, the investigator is collecting evidence from internal servers and shared drives that are part of the organization's on-premises infrastructure. These repositories typically store centralized data such as user files, audit logs, access records, and application artifacts.
This approach directly aligns with network collection , an eDiscovery methodology in which data is acquired remotely over the organizational network from file servers, database servers, shared storage, and internal repositories . Network collection is commonly used in enterprise investigations because it allows investigators to gather large volumes of data efficiently without physically seizing individual endpoint devices.
Cloud-based collection (Option B) applies only when data is hosted on third-party cloud platforms such as AWS, Azure, or Google Cloud. Email collection (Option C) is limited to mail servers and messaging systems, while mobile device collection (Option D) focuses on smartphones and tablets. None of these accurately describe the centralized, internal infrastructure outlined in the scenario.
The CHFI v11 Exam Blueprint emphasizes eDiscovery collection methodologies as part of forensic readiness and investigation workflows, highlighting network collection as the appropriate technique for acquiring evidence from organizational servers and shared drives while maintaining integrity and chain of custody
