サイバー攻撃を受けた組織は、影響を受けたユーザーのコンピューターのフォレンジック分析を実行しています。このプロセスをレビューする情報システム監査人にとって、次のうちどれが最も懸念すべきですか?
正解:C
Explanation
The chain of custody has not been documented is a finding that should be of greatest concern for an IS auditor reviewing a forensic analysis process of an organization that has suffered a cyber attack. The chain of custody is a record of who handled, accessed, or modified the evidence during a forensic investigation. Documenting the chain of custody is essential to preserve the integrity, authenticity, and admissibility of the evidence in a court of law. The other options are less concerning findings that may not affect the validity or reliability of the forensic analysis process. References:
