Why is it important to preserve volatile data during an investigation?

Preserving volatile data is crucial in an investigation because it can contain critical information necessary for understanding the state of a system at a specific moment in time. Volatile data includes elements such as active processes, network connections, running programs, and system memory. This form of data is temporary and can be lost when a device is powered off or rebooted. Thus, capturing this information can provide invaluable insights into the actions that occurred leading up to an incident, revealing potential breaches, ongoing attacks, or unauthorized access.

In forensic investigations, this type of information can help build a timeline of events, identify unauthorized users or processes, and understand the overall behavior of malware or other malicious activities present on a system. Therefore, preserving volatile data plays a significant role in ensuring that investigators have access to comprehensive and relevant information needed for thorough analysis and reporting.
