Cloud Identity Super Admin 2sv Enforcement 2

What this solution is

This solution establishes a structured identity governance model in Cloud Identity by isolating privileged super administrator accounts into a dedicated Organizational Unit (OU). By applying targeted policies to this OU, administrators can mandate hardware security keys (such as Titan Security Keys) for 2-Step Verification (2SV) and restrict insecure self-service account recovery channels.

How it meets the requirements

• Privileged Account Isolation: Placing super administrators into a dedicated OU allows security teams to define granular, high-security policies that apply exclusively to privileged users without disrupting standard users across the organization.
• Phishing-Resistant 2-Step Verification: Mandating Security Keys only (FIDO2/WebAuthn hardware tokens) ensures that second-factor authentication cannot be intercepted by man-in-the-middle or credential phishing attacks, satisfying Google Control ID CI-CO-6.1 and CI-CO-6.2.
• Secure Account Recovery: Disabling automated user self-service password recovery for the administrator OU ensures that an attacker cannot bypass strong 2SV requirements by compromising recovery email addresses or mobile phone numbers.

Key advantages and capabilities

• Granular Policy Inheritance: Cloud Identity applies organizational unit policies hierarchically, allowing distinct 2SV enforcement modes, grace periods, and credential restrictions across OUs.
• Cryptographic Protection: Hardware keys provide cryptographic proof of domain binding, neutralizing sophisticated phishing and reverse-proxy attacks.
• Defense-in-Depth for Admins: Protects the root of administrative trust across Google Cloud projects, Organization Policies, and resource hierarchies.
• Streamlined Auditing: Grouping all super admin principals into a single OU simplifies periodic access certification and compliance reporting.

Why this is optimal

Isolating privileged identities into an administrative OU is the Google Cloud standard architecture for enforcing elevated controls. Applying FIDO2/Titan Security Key enforcement exclusively to this OU guarantees maximum identity assurance for privileged accounts while preventing account takeovers via legacy recovery mechanisms.
