What should be the approach when collecting data from an active device?

When collecting data from an active device, the approach of continuous collection is essential because it allows for the monitoring of real-time activities and interactions occurring within that device. This method is critical in forensic investigations, particularly in situations involving potential evidence of criminal activity. Continuous collection ensures that data is not missed and provides a comprehensive picture of actions, transactions, or communications that may be vital for understanding the case.

Immediate backup, while important in preserving data, may not capture the ongoing activities or changes that are occurring at that moment. Powering off a device can lead to the loss of volatile data, which is information that only exists in the device's memory while it is powered on. Restarting the device can further complicate data retrieval, potentially altering the state of evidence. Logging all activities can be useful but does not inherently capture data in real-time, as continuous collection does.

Therefore, continuous data collection is the preferred approach as it maximizes the amount of relevant evidence preserved and offers law enforcement a better opportunity to understand the events and actions that have taken place on the device.
