When preserving a crime scene for digital evidence, it is crucial to maintain the integrity of the evidence while also ensuring that volatile data is not lost. The initial actions should include photographing all evidence, which helps document the scene and the location of digital devices. This is important for later analysis and may be required for legal proceedings. Triage is the process of determining the importance of digital evidence and whether live data capture is necessary. Live data capture can be essential because some data can be lost if a device is powered down, such as encryption keys or active network connections1.
