Graham G. has released an updated version (v1.1) of the M365 Breakglass Maturity Model, incorporating critical feedback from cloud security experts. This model focuses on emergency access (“breakglass”) strategies for Microsoft 365 environments, ensuring resilience against outages, misconfigurations, or attacker lockouts.
Key Enhancements in v1.1:
- Level 6: Isolated Resilience (e.g., red tenant Break Glass Access paths).
- Offline Recovery Support: QR codes, printed passphrases, and physical failovers.
- Scoped Conditional Access Exemption Guidance.
- Recovery Planning for Microsoft outages and identity provider (IDP) failures.
- Support for Alternate IDPs or external identity control planes.

You Should Know:
1. Implementing Breakglass Accounts in Azure AD
Use PowerShell to create emergency accounts with time-bound access:
New-MgUser -DisplayName "Breakglass_Admin" -AccountEnabled $true -PasswordProfile @{Password="SecurePassword123!"} -MailNickname "breakglass"
Set-MgUserLicense -UserId "[email protected]" -AddLicenses @() -RemoveLicenses @()
2. Enforcing Conditional Access Exemptions
Exclude breakglass accounts from MFA policies via Azure CLI:
az rest --method PATCH --uri 'https://graph.microsoft.com/v1.0/policies/conditionalAccessPolicies/{id}' --body '{"excludeUsers": ["[email protected]"]}'
3. Linux-Based Backup for Offline Recovery
Store encrypted backup keys on a Linux air-gapped system:
Generate a GPG-encrypted backup gpg --symmetric --cipher-algo AES256 --output breakglass_backup.gpg /path/to/credentials.json
4. Windows Event Log Monitoring for Breakglass Usage
Detect unauthorized access attempts via PowerShell:
Get-WinEvent -LogName Security | Where-Object { $_.Message -like "Breakglass_Admin" }
5. QR Code Recovery with Python
Generate QR codes for offline passphrases:
import qrcode
qr = qrcode.make("EMERGENCY_ACCESS_CODE: XXXX-XXXX-XXXX")
qr.save("breakglass_qr.png")
What Undercode Say:
The M365 Breakglass Maturity Model is a critical framework for organizations relying on cloud infrastructure. By integrating offline recovery, isolated resilience, and conditional access exemptions, teams can mitigate risks of total lockout. Practical implementation requires:
– Automated monitoring (e.g., SIEM alerts for breakglass account usage).
– Regular drills to test recovery procedures.
– Air-gapped backups (e.g., Linux-hosted encrypted vaults).
Expected Output:
A comprehensive cloud security strategy combining Microsoft 365 breakglass protocols, offline recovery mechanisms, and cross-platform (Windows/Linux) command automation.
