Device Encryption & Security

Procedure: SP-007  |  Version: 1.5  |  Last Updated: 1 April 2025  |  Owner: Marcus Chen

Purpose: To verify and enable device encryption, set BIOS/UEFI passwords, and configure secure boot on customer devices when requested.

BitLocker (Windows)

  1. Check current encryption status: Manage-bde -status C:
  2. Enable BitLocker: Manage-bde -on C: -RecoveryPassword
  3. Save the recovery key to S:\Security\BitKeys\[JobNumber].txt
  4. NEVER store the recovery key on the encrypted drive itself
  5. Verify encryption is active: Manage-bde -status C: should show "Protection On"

FileVault (macOS)

  1. System Preferences → Security & Privacy → FileVault → Turn On FileVault
  2. Save the recovery key to S:\Security\FileVaultKeys\[JobNumber].txt
  3. Ensure the customer has a way to unlock the Mac (Apple ID or local password)
  4. Verify encryption is progressing (shown in the FileVault window)

BIOS/UEFI Passwords

  • Set BIOS password only if customer requests it (document in the job record)
  • Enter BIOS (Del or F2 at boot) → Security tab → Set Supervisor/User Password
  • Enable Secure Boot where supported (under Boot tab)
  • NEVER set a BIOS password without the customer's explicit knowledge
  • Record BIOS passwords in the job record — the customer will need these

Secure Boot Verification

  1. Enter BIOS and verify Secure Boot is enabled
  2. Check that the OS is booted in UEFI mode (not Legacy/CSM)
  3. Verify TPM 2.0 is enabled (required for BitLocker and Windows 11)
  4. Run tpm.msc in Windows to confirm TPM status

Security Note: Always store encryption keys and passwords securely in the designated server locations. Never write them on sticky notes attached to the device. Customer security is our responsibility.
