The primary responsibility of a forensic investigator in the evidence handling process is to create an image backup of the original evidence without tampering with potential evidence. This is crucial because maintaining the integrity of the evidence is fundamental to any forensic investigation. A forensic image is a bit-by-bit copy of the original data, which ensures that the original evidence remains unaltered, thus preserving its authenticity for legal proceedings.

Creating an image allows forensic investigators to analyze the data and extract relevant information while ensuring that the original source, which may be subject to legal scrutiny, is preserved in its untouched state. This meticulous approach is vital, as any alteration to the original evidence can lead to questions regarding its validity, potentially compromising an entire case.

The other options, while they encompass elements relevant to investigations, do not directly address the specific responsibilities tied to evidence handling. For instance, taking permission from employees may facilitate the process but is not the core responsibility of ensuring that evidence is handled properly. Hardening network security is more related to preventative measures rather than the investigative responsibilities once a breach or incident has occurred. Maintaining confidentiality is essential, but hiding evidence from law enforcement would be unethical and counterproductive in the pursuit of justice.
