The process of forensic investigation to preserve evidence, the process

The time required for a digital forensic investigation can range from a few hours to several months, and varies greatly depending on the number of devices to be investigated, the items to be investigated, and the purpose of the investigation.

The investigation begins with an initial investigation and hearing. After clarifying the purpose of the investigation, data preservation and collection begins. Next, the collected data is analyzed using specialized analysis tools to clarify the history and path of damage, and an investigation report is prepared.

Initial Investigation

First, we clarify the purpose of the investigation. Through interviews, we determine the devices, systems, and timeframe to be surveyed, and secure the necessary tools, personnel, and other resources for the survey.

Data collection and preservation

We secure the devices to be surveyed and properly preserve the collected digital data to prevent accidental deletion or destruction. Duplicate the entire data set to be surveyed.

Data Processing, Analysis, and Recovery

Information is read from the target device and copied data, and deleted files are restored if any. Optimize the data for easy analysis.

Data Analysis

This is the process of analyzing the information that has been organized for the purpose of the investigation. We analyze the information to determine whether it is consistent with the purpose of the investigation and whether it can be used as evidence, while also making full use of our knowledge of the law.

Reporting

The results obtained from the analysis are compiled and submitted in a report. The report will contain the details and facts of the investigation and will be made available to the court of law.

Cautions and challenges of forensic investigations - Ensuring the preservation of evidence

The series of forensic investigations requires a wide range of digital, legal, and other expertise. If a company does not have the specialized knowledge and technical know-how in-house, it may not be able to properly conduct the investigation and mishandle the data, resulting in "secondary damage".

Especially in the case of important incidents, an objective investigation by a third party is often necessary to avoid suspicion of a cover-up, and there are limits to what a company can do on its own.

Thus, it is difficult to conduct forensic investigations on one's own, so the shortcut is to hire an investigation company with a proven track record and technical capabilities.

When requesting a forensic investigation, consult a vendor with a proven track record and technical capabilities.

In-house forensic investigation has its limitations. The shortcut to a solution is to request an investigation company with a proven track record and technical capabilities.
