The primary goal of a forensic investigator during a cybercrime analysis is to preserve and document evidence. This process is crucial because it ensures that all collected data is usable in a legal context. Forensic investigators need to maintain the integrity of digital evidence; any alteration could compromise the validity of the findings in court.

Preservation involves creating a bit-for-bit copy of data, thus safeguarding the originals from any tampering or loss. Documentation extensively records every step taken throughout the investigation, detailing how evidence was collected, handled, and analyzed. This thorough documentation serves as a chain of custody record, which is vital for demonstrating that the evidence has not been altered since it was collected and is reliable.

While identifying system vulnerabilities, enhancing network security, and reporting to law enforcement are important aspects of cybersecurity and incident response, they are secondary to the fundamental purpose of gathering and securing evidence for potential prosecution. The rigor with which this evidence is preserved and documented can determine the outcome of a legal case, making it the investigator's top priority.
