MFA for Cloud Admin Accounts
Plain English Translation
Organizations must protect administrative access to their cloud environments by requiring multi-factor authentication (MFA) for all cloud admin accounts. Additionally, to limit the impact if an internal network is compromised, the accounts used to manage cloud services must be entirely separate from the accounts used for internal network administration. This prevents a hacker who compromises an internal admin from automatically gaining control over cloud infrastructure.
Technical Implementation
Use the tabs below to select your organization size.
Required Actions (startup)
- Enforce MFA on all root and administrative accounts in cloud services.
- Create separate login IDs for internal versus cloud administration.
- Disable shared admin accounts and assign dedicated accounts to individuals.
Required Actions (scaleup)
- Implement Single Sign-On (SSO) with strong conditional access policies enforcing step-up authentication for cloud admin roles.
- Use hardware security keys or authenticator apps for cloud admin MFA instead of SMS.
- Regularly audit cloud admin group memberships to ensure least privilege.
Required Actions (enterprise)
- Deploy Privileged Access Management (PAM) for just-in-time, time-bound cloud admin access.
- Enforce strict conditional access policies restricting cloud admin logins to compliant, corporate-managed devices.
- Automate the monitoring and alerting of cloud admin logins and configuration changes.
CyberSecure Canada Section 6.2.3.1(e) requires organizations to ensure that all administrative accounts for cloud services use multi-factor authentication (MFA). It also mandates that these cloud admin accounts differ from internal administrator accounts.
Enforce MFA by configuring Microsoft Entra ID (formerly Azure AD) Conditional Access policies that explicitly require strong MFA for all users holding administrative directory roles. Ensure legacy authentication protocols are disabled to prevent bypasses. To keep this reliable over time, tools like WatchDog Security's Posture Management can help flag cloud identity configurations that indicate MFA enforcement gaps and provide remediation guidance.
Yes, AWS root accounts and any IAM users or roles with administrative privileges must have MFA enforced. Hardware MFA tokens are strongly recommended for root accounts to ensure maximum security.
Cloud admin accounts should have unique usernames and credentials separate from internal domain admin accounts (e.g., Active Directory). This separation ensures that a compromised internal admin account cannot be seamlessly leveraged to take over cloud services.
Best practices involve creating a separate, dedicated identity (such as 'admin.jdoe@domain.com') strictly used for cloud administration. The user maintains a standard account ('jdoe@domain.com') for daily tasks like email and web browsing.
Break-glass accounts must still be highly secured, typically utilizing FIDO hardware keys stored in a physically secure location like a safe. They should be excluded from routine conditional access lockouts but strictly monitored for any login activity.
Collect IAM policy exports, Conditional Access policy configurations, and user directory extracts showing MFA status for all admin groups. Provide documentation confirming that internal and cloud admin account naming conventions differ. Tools like WatchDog Security's Compliance Center can help organize this evidence against the control, track review cadence, and keep an audit-ready record of changes over time.
While SMS MFA is technically better than no MFA, it is highly vulnerable to SIM-swapping attacks. Organizations should use phishing-resistant methods like FIDO security keys or strong authenticator apps for highly privileged cloud admin accounts.
Access to cloud administrative roles and their corresponding MFA configurations should be reviewed at least quarterly. Organizations must ensure that terminated or transferred employees have their cloud admin access revoked immediately.
Common gaps include failing to enforce MFA on API access, overlooking service accounts with admin rights, or allowing legacy authentication. Prevent these by strictly enforcing MFA across all access methods, using secure credential rotation for service principals, and disabling basic authentication.
Cloud admin MFA can drift over time as roles change, new tenants are added, or policies get modified. Tools like WatchDog Security's Compliance Center can track this control, centralize evidence, and surface gaps so teams can remediate before an audit.
Auditors typically expect a clear identity model showing different credentials, role assignments, and lifecycle controls for cloud versus internal administration. Tools like WatchDog Security's Asset Inventory can help map identities across environments and support documentation that demonstrates this separation.
