Building A Digital Forensics Lab With Tableau Write-Blocker Kits

Digital forensics professionals rely on specialized tools to ensure data integrity during investigations. The recent addition of two Tableau Forensic Write-Blocker Kits significantly enhances forensic acquisition capabilities:

1. Tableau Forensic SATA/IDE Bridge TK35U+ Bundle

T35u Tableau Forensic SATA/IDE Bridge
TP7 Power Supply + Line Cord
Cables: TC2-8-R2, TC3-8, TC5-8-R2, TC6-8, TC-U

2. Tableau PCIe Adapter Bundle TKDA7-3PC-BNDL

TDA7-1 (PCIe Card SSD Adapter)
TDA7-2 (M.2 SSD Adapter)
TDA7-3 (Apple SSD Adapter)
TC-PCIE-4 (PCIe Adapter Cable)

Why Write-Blockers Matter

Preserve evidence integrity by enabling read-only access.
Support multiple storage types (SATA, IDE, M.2, PCIe, Apple SSDs).
Ensure court-admissible forensic images without altering original data.

You Should Know:

How to Use Tableau Write-Blockers for Forensic Imaging

Step 1: Connect the Storage Device

For SATA/IDE drives, use the TK35U+ with appropriate cables.
For PCIe/NVMe/Apple SSDs, use the TDA7 adapters.

Step 2: Verify Write-Blocking Status

On Linux, check if the drive is mounted in read-only mode:
```
dmesg | grep -i "write-protected"
mount | grep /dev/sdX
```
On Windows, use DiskPart:
```
diskpart 
list disk 
attributes disk 
```

Step 3: Acquire a Forensic Image

Linux (dd command):

sudo dd if=/dev/sdX of=evidence.img bs=4M status=progress

Windows (FTK Imager or Guymager):

guymager -d /dev/sdX -o /output/evidence.E01

Step 4: Verify Image Integrity

Generate a SHA-256 hash:
```
sha256sum evidence.img
```
Compare with the original drive’s hash:
```
sha256sum /dev/sdX
```

2. Essential Digital Forensics Commands

Linux Commands

List connected storage devices:
```
lsblk 
fdisk -l 
```
Check disk I/O activity:
```
iostat -x 1 
```

Recover deleted files (ext4):

sudo extundelete /dev/sdX --restore-all

Windows Commands

Check USB device history:

Get-WinEvent -LogName "Microsoft-Windows-DriverFrameworks-UserMode/Operational" | Where-Object {$_.Id -eq 2003}

Extract Prefetch files (forensic artifacts):
```
dir C:\Windows\Prefetch 
```

3. Setting Up a Forensic Workstation

Kali Linux (Forensics Mode):

sudo apt install autopsy guymager sleuthkit

Windows (FTK Imager + Volatility):
```
choco install ftkimager volatility 
```

What Undercode Say:

A well-equipped digital forensics lab requires reliable write-blockers like Tableau’s TK35U+ and TDA7 adapters. These tools ensure forensic soundness and legal compliance in investigations.

Expected Output:

Forensic images (E01, RAW, AFF)
Hash verification logs
Chain-of-custody documentation

Prediction:

As SSD and NVMe adoption grows, forensic tools will evolve to handle encrypted and TRIM-enabled drives more efficiently. Expect AI-assisted forensic analysis to speed up investigations in the next 5 years.
