Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly enforces authorization checks that were missing, blocking unauthorized retrieval of the enrolled-student email list.
Ensures users and roles receive only the minimum privileges required, preventing broad read access to batch enrollment data by default.
Controls information flows so that enrollment-list data cannot be returned to subjects lacking the necessary authorization attributes.

Defining, enforcing, and reviewing access authorizations and least privilege directly prevents incorrect authorization checks.

Requiring consistency between access rights and classification plus formal approval steps ensures that the authorization logic correctly distinguishes between entities that should and should not be granted access.
Enforcing policy-driven approval and role-change reviews stops incorrect or stale authorization decisions from remaining in effect after job changes or terminations.
By tying access rights to identity, device, location and classification, the control reduces the likelihood that an authorization decision will be based on an incorrect or bypassed policy.
