DO record the make, model and serial numbers of the devices in question.

DO NOT remove the batteries to collect this information.

DO NOT ask IT personnel to run a data collection or conduct a forensic investigation.

Collections must be conducted by staff trained in forensic processes, procedures and methodologies. This ensures evidence is preserved in an admissible manner.

DO (if possible) take possession of an entire suspect computer, not just hard drives.

Important information can be obtained from physical devices, including date/time settings and boot-up order.

DO NOT log into a suspect device as the suspect custodian.

? This can make it nearly impossible to tie data and actions to a certain suspect.

Page 11: D4 | The Dos and Don'ts of Digital Evidence Preservation

DO NOT leave devices connected to a company intranet, network, or the Internet.

Page 12: D4 | The Dos and Don'ts of Digital Evidence Preservation

DO store devices in a secured location until handed over for imaging and analysis.

Securing devices and their data ensures potential evidence isn’t tampered with or altered in any way.
