Which type of evidence may require stricter procedures for preservation due to its volatile nature?

Processor cache is indeed a type of evidence that may require stricter procedures for preservation due to its volatile nature. The processor cache stores temporary data that is actively being used by the CPU for quick access, making it highly transient. If a device is powered down or experiences a disruption, any data held in the cache can be lost permanently.

Consequently, digital forensics professionals must act quickly to capture this information before any potential loss occurs. This often involves using specialized tools or techniques to image the memory while the system is still operational, ensuring that crucial data that could provide insights into user activity or system state is not lost.

This need for rapid action distinguishes processor cache from other types of evidence, such as archival media, cloud storage, or USB drives, which are generally more stable and can be preserved with a longer window of opportunity for acquisition.
