This question aligns with CHFI v11 objectives underRegulations, Policies, and EthicsandSearch and Seizure of Digital Evidence. Before any forensic examination can legally take place—especially an on-site examination involving computers and email servers—the investigator must obtainproper legal authorization. In practice, this authorization is enforced through the lawfulseizure of systems and accounts, either via a search warrant, court order, or explicit consent from the system owner.

CHFI v11 emphasizes that digital forensic investigations must strictly follow legal procedures to ensure evidence admissibility and avoid violations of privacy or due process. Seizing the computer systems and email accounts establishes lawful control over the evidence, enables proper chain of custody documentation, and prevents further tampering or destruction of data. Only after seizure and authorization can investigators safely proceed with technical tasks such as retrieving email headers, recovering deleted messages, or analyzing email content.

The other options describe forensic analysis steps that occurafterlegal access has been granted. Performing them without authorization could invalidate evidence and expose the investigator to legal liability. Therefore, consistent with CHFI v11 best practices and legal requirements,seizing the computer and email accountsis the correct initial step before proceeding with the forensic examination.
