Restrict Guest Invitation Permissions for Education & Research
How education & research organizations should implement EXT-01 for Microsoft 365 security and compliance.
Education & Research organizations face unique security challenges when managing Microsoft 365 environments. The EXT-01 control (Restrict Guest Invitation Permissions) is particularly important for this sector due to cis and nist-800-53 requirements.
Why Education & Research Organizations Need This Control
Education & Research organizations face specific regulatory requirements including cis, nist-800-53, soc2. The EXT-01 control helps address these requirements by:
- Only admins and users in the Guest Inviter role can invite guests
- Member users cannot invite guests
