What is the first step required in preparing a computer for forensics investigation?

The first step required in preparing a computer for forensic investigation is to ensure that the integrity of the evidence is maintained. This involves not turning the computer off or on, running any programs, or attempting to access data. This step is crucial because altering the state of the computer can lead to changes in volatile data, which could be lost if the system is powered down or restarted. Volatile memory, which includes RAM, contains crucial information that is only present while the computer is powered on, and any changes made could compromise the investigation.

Maintaining the original state of the computer allows forensic investigators to capture the most complete and accurate representation of the data available at the time of the incident. Each action taken on the device can lead to data being altered or deleted, which can undermine the integrity of the evidence. Therefore, preserving the system in its current operational state is essential for a successful forensic analysis.
