What it checks
Location-based Conditional Access policies restrict access based on IP address ranges, countries, or named locations. Without location controls, attackers can authenticate from any geographic location, making it harder to detect and prevent unauthorized access from suspicious or high-risk regions.
Recommended value
Location-based policies configured to block or require additional controls for access from untrusted locations
Remediation
Review existing named locations and ensure trusted corporate IP ranges and countries are accurately defined. Create Conditional Access policies that require MFA or block access from untrusted locations, particularly for privileged accounts and sensitive applications. Regularly update named location definitions as corporate network infrastructure changes.
Fixture-proven verdicts
Every verdict below is proven by a golden fixture in the module's gating test suite. This table derives from the last green run; it cannot be edited by hand.
| Scenario | Expected verdict |
|---|---|
| clean | PASS |
| known-bad | WARN |
| throttled | Not Assessed |
