Block Legacy Authentication for FedRAMP Compliance
Learn how ID-02 helps you meet FedRAMP requirements for Microsoft 365 and Entra ID security.
Organizations pursuing FedRAMP compliance need to address block legacy authentication as part of their security program. The ID-02 control maps directly to FedRAMP requirements, helping demonstrate compliance while strengthening your security posture.
How ID-02 Addresses FedRAMP Requirements
FedRAMP requires organizations to implement controls around block legacy authentication. The ID-02 control provides:
- A Conditional Access policy blocks legacy authentication protocols (IMAP, POP3, SMTP, older Office clients)
- No exceptions for legacy protocols except documented service accounts
These measures directly support FedRAMP compliance by ensuring proper identity security in your Microsoft 365 environment.
Implementation for Compliance
To satisfy FedRAMP 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 FedRAMP 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 FedRAMP
Legacy protocols like IMAP and POP3 cannot enforce MFA. Attackers specifically target these protocols to bypass your MFA policies. Blocking them closes a major attack vector.
Implementing ID-02 is an important step toward FedRAMP compliance. Combined with TrueConfig's continuous monitoring, you can demonstrate ongoing adherence to FedRAMP requirements.
