Question 620
A company disables legacy authentication in its cloud applications but one old integration continues submitting basic-auth credentials. The change owner plans to: Migrate the integration to supported modern authentication and enforce policy against legacy protocols. Which precaution directly prevents a predictable failure of this approach?
Explanation
Correct Answer
The specific rollout control is Inventory application owners and validate supported replacement flows before blocking old clients. It protects the proposed intervention 'Migrate the integration to supported modern authentication and enforce policy against legacy protocols.' against the failure mode that legacy authentication protocols may bypass stronger interactive sign-in protections. Success should also be checked through: The upgraded client obtains the required token while the legacy attempt is rejected.
Incorrect Answers
MFA prompts and conditional access failures are not necessarily password validation errors. The proposed change also needs protection against this risk: Legacy authentication protocols may bypass stronger interactive sign-in protections. The applicable safeguard is: Inventory application owners and validate supported replacement flows before blocking old clients.
Audit-only reporting records weak attempts but does not necessarily prevent them. The proposed change also needs protection against this risk: Legacy authentication protocols may bypass stronger interactive sign-in protections. The applicable safeguard is: Inventory application owners and validate supported replacement flows before blocking old clients.
Successful invitation does not override home or resource tenant sign-in policy restrictions. The proposed change also needs protection against this risk: Legacy authentication protocols may bypass stronger interactive sign-in protections. The applicable safeguard is: Inventory application owners and validate supported replacement flows before blocking old clients.
