Block or Require MFA for Risky Sign-Ins for Zero Trust Compliance
Learn how CA-03 helps you meet Zero Trust requirements for Microsoft 365 and Entra ID security.
Organizations pursuing Zero Trust compliance need to address block or require mfa for risky sign-ins as part of their security program. The CA-03 control maps directly to Zero Trust requirements, helping demonstrate compliance while strengthening your security posture.
How CA-03 Addresses Zero Trust Requirements
Zero Trust requires organizations to implement controls around block or require mfa for risky sign-ins. The CA-03 control provides:
- An Identity Protection sign-in risk policy is enabled
- High-risk sign-ins are blocked
- Medium-risk sign-ins require MFA
These measures directly support Zero Trust compliance by ensuring proper conditional_access security in your Microsoft 365 environment.
Implementation for Compliance
To satisfy Zero Trust requirements with this control:
- **Enable the control** - Use TrueConfig's one-click remediation
- **Document your implementation** - Record how the control was configured
- **Maintain evidence** - TrueConfig automatically logs compliance status
- **Monitor continuously** - Track any deviations from the expected state
Evidence Collection
For Zero Trust audits, you'll need to demonstrate:
- Current configuration state
- Historical compliance data
- Remediation actions taken
- Continuous monitoring in place
TrueConfig provides all of this evidence through its audit trail and reporting features.
Why This Control Matters for Zero Trust
Microsoft analyzes each sign-in for anomalies (impossible travel, anonymous IP, malware-linked IPs). Risk-based policies automatically escalate protection when threats are detected, without user friction during normal access.
Implementing CA-03 is an important step toward Zero Trust compliance. Combined with TrueConfig's continuous monitoring, you can demonstrate ongoing adherence to Zero Trust requirements.
