# Workflows - Implementing Disk Encryption with BitLocker
|
|
|
|
## Workflow 1: Enterprise BitLocker Deployment
|
|
|
|
```
|
|
[Pre-deployment assessment]
|
|
│
|
|
├── Verify TPM 2.0 across fleet
|
|
├── Confirm UEFI/Secure Boot
|
|
├── Plan recovery key escrow (AD DS or Azure AD)
|
|
│
|
|
▼
|
|
[Configure GPO/Intune policy]
|
|
│
|
|
├── Set encryption method (XTS-AES 256)
|
|
├── Configure key protectors (TPM + PIN for laptops, TPM for desktops)
|
|
├── Enable recovery key escrow
|
|
│
|
|
▼
|
|
[Pilot deployment (test group)]
|
|
│
|
|
├── Verify encryption completes without errors
|
|
├── Test recovery key retrieval
|
|
├── Verify no boot issues
|
|
│
|
|
▼
|
|
[Production rollout (phased)]
|
|
│
|
|
▼
|
|
[Monitor encryption status via Intune/SCCM reports]
|
|
│
|
|
▼
|
|
[Verify 100% coverage, address failures]
|
|
```
|
|
|
|
## Workflow 2: BitLocker Recovery Process
|
|
|
|
```
|
|
[User locked out (BitLocker recovery screen)]
|
|
│
|
|
▼
|
|
[User provides Recovery Key ID to helpdesk]
|
|
│
|
|
▼
|
|
[Helpdesk retrieves recovery key]
|
|
│
|
|
├── AD DS: RSAT BitLocker Recovery Password Viewer
|
|
├── Azure AD: Azure Portal → Devices → BitLocker keys
|
|
├── Intune: Intune Portal → Devices → Recovery keys
|
|
│
|
|
▼
|
|
[User enters 48-digit recovery key]
|
|
│
|
|
▼
|
|
[Investigate why recovery was triggered]
|
|
│
|
|
├── BIOS/firmware update ──► [Expected, no action]
|
|
├── TPM failure ──► [Replace TPM or re-encrypt]
|
|
├── Boot configuration change ──► [Review change, re-seal TPM]
|
|
└── Potential tampering ──► [Security investigation]
|
|
```
|
|
|
|
## Workflow 3: Key Rotation
|
|
|
|
```
|
|
[Quarterly key rotation policy]
|
|
│
|
|
▼
|
|
[Generate new recovery password]
|
|
│
|
|
▼
|
|
[Backup new key to AD/Azure AD]
|
|
│
|
|
▼
|
|
[Remove old recovery password protector]
|
|
│
|
|
▼
|
|
[Verify new key works in test recovery]
|
|
```
