What is logical acquisition in digital forensics?

Logical acquisition in digital forensics refers to the process of collecting specific files and folders from a device rather than creating a complete image of the entire storage medium. This method is particularly useful when investigators are interested in particular data or when time and storage considerations make a full acquisition impractical.

By focusing on selected files and folders, logical acquisition allows forensic examiners to efficiently target relevant evidence, especially in cases where only certain aspects or documents are critical to an investigation. This can include documents, images, or emails that are pertinent to the case at hand.

While other methods of acquisition, such as physical acquisition, involve making a complete image of the storage device, logical acquisition offers a more selective approach, which can save time and resources while still yielding essential data relevant to the inquiry. This technique is often utilized when handling devices with large amounts of data or when the examiners need specific information to answer a legal question.
