Creating a digital forensic laboratory: Tips and Tricks

by Igor Mikhaylov2018-04-16

Creating a digital forensic laboratory is a responsible step. The effectiveness of the laboratory depends on what software, hardware and equipment will be purchased.

DFC specialists took part in the creation and upgrade of several digital forensic laboratories owned by state organizations and private entities and today they will share their tips and tricks.

A FORENSIC WORKSTATION

 

Choosing a workstation configuration is an important step. The effectiveness of digital examiners depends on the way the workstation is configured.

However, we want to pay special attention to one point: the workstation should work as quietly as possible. Imagine an open space where several powerful computers are installed, each of which makes a noise like a server. The employees’ headache and poor health are guaranteed. Silent workstation performance is achieved by using low-noise fans and passive cooling systems.

Do not use top hardware. The idea to buy the most expensive processor, memory, motherboard for your new workstation is not the best one. We had many problems with the workstation in which similar components were used.

In our opinion, this configuration is optimal today:

OS: Windows 10 Pro 64-bit

CPU (2):  E5-2660 v4 (14 core)

RAM: 64 GB DDR-42133 ECC

OS Drive: 1 TB SSD

Temp/Cache/DB Drive: 256 GB SSD

Data Drive: 8 TB 7200rpm

RAID Drives: 5×4 TB 7200rpm

Video Card: GeForce GTX 1080

We recommend to use two or more monitors for each workstation.

The most effective work is achieved when a digital examiner uses two workstations in its work.

Use NET Storages to store cases, forensic images, etc. NET Storages with a volume of 100-150 TB proved to be quite effective.

Use 10Gbit Net Cards. They will allow you to transfer data from the workstation to NET Storages quickly.

FORENSIC SOFTWARE

It’s a good idea to have as more different forensic software in the digital laboratory. This will allow a forensic examiner to make cases as quickly and efficiently as possible. Also, this makes it possible to recheck the results of the research effectively.

However, if you have a limited budget, we recommend buying this software:

Windows 10 Pro

Office 365

Antivirus software

X-ways Forensic

AXIOM (Magnet Forensics)

The rest of the tools can be purchased as the laboratory develops.

Also, a lot of research can be done using freeware tools. Sometimes these tools outperform functionality of commercial tools.

 

CASE MANAGEMENT SOFTWARE

If you create a digital forensic laboratory in a government organization, for example in the police department, then most likely they have their own case management software and then your task  is just to add a new laboratory to the network of existing ones.

In other cases, you can use free and chargeable CRM systems. Besides, some CRM systems can be adapted to your management needs.

We recommend Kirjuri (Kirjuri is a web application for managing cases and physical forensic evidence items.) and Lima Forensic Case Management of all the specialized tools.

 

VIDEO FORENSICS

We recommend using a separate workstation for the production of video forensics cases. We recommend using the following forensic tools:

DVR Examiner

Amped FIVE

Elecard

Very good results of recovering deleted videos can be obtained using X-ways Forensic. We have written about this tool above.

 

MOBILE FORENSICS

 

We recommend using a separate workstation to carry out mobile forensics research.

There are a lot of tools for mobile forensics. That is why it is difficult for a beginner to understand what they need to carry out this research effectively. We recommend using the following mobile forensic tools:

UFED 4PC (with CHINEX, UFED Camera Kit)

Cellebrute UFED Touch

Cellebryte cables and adapters

Oxygen Forensics DETECTIVE

XRY

Elcomsoft Mobile Forensic Bundle

We recommend using SР Flash tool to retrieve data from MTK based phones.

A Faraday Box (Ramsey)

 

CLOUD FORENSICS

We recommend using the following tools for Cloud forensics:

UFED Cloud Analyzer

Oxygen Forensics DETECTIVE

Elcomsoft Cloud eXplorer

 

MOBILE DATA RECOVERY

We recommend using flashers for JTAG research:

Easy Z3x JTAG BOX

Octoplus Box

Samsung anyway S101

 

For Chip-off we recommend using:

VISUAL NAND RECONSTRUCTOR (STARTER KIT, Rusolut)

SMARTPHONE KIT (Rusolut)

CHINESE SMARTPHONE KIT (Rusolut)

NuProg-E UFS/EMMC Programmer

IN-UFS-Socket  BGA       Opentop

N-UFS-065-BGA095-115130-02O BGA    Opentop

N-UFS-050-FBGA153-115130-02O BGA Opentop

 

We recommend using Weller WHA 300 Hot Air Reworking Station or Ersa HR100 Hybrid Rework system for disordering chips.

 

DATA RECOVERY (HARD DRIVES, FLASH DRIVES, MEMORY CARDS)

 

We recommend using a separate workstation for the production of Data recovery. You will need special hardware and tools for data recovery:

PC-3000 Express Professional System  (Acelab)

Data Extractor Express (Acelab)

PC-3000 Flash (Acelab)

 

FURNITURE

 

Many people believe that it is enough to buy ordinary office desks and chairs to equip a digital forensic lab. However, it is not so. Tables must have abrasion resistant coatings. We recommend the use of special laboratory tables.

Office chairs should be as convenient as possible. We recommend using not ordinary office chairs but gaming chairs.

The table where the electronic equipment is assembled and disassembled should be equipped with an antistatic mat and an antistatic bracelet.

 

 

Happy forensicating!

    Well, thank you for such amazing post I really feel good after read this. Keep post always like this. Actually, I was needed a private investigator for one of my issue where I felt very bad because I could not found any help. Then I got ICFECI through my friend who suggest me this and it was very useful for me in solving my case easily.

    This was written in April 2018. I got this information from Igor Mikhaylov’s (one of the authors) LinkedIn page.
