修正方法: ガイダンスまたは IaC パッチ

1. In the Oracle Cloud Infrastructure Console, access the Fusion SaaS environment's network configuration 2. Enable the Access Control List feature if not already active 3. Add the organization's trusted public IP addresses, CIDR ranges, and/or OCI Virtual Cloud Networks (VCNs) to the ACL 4. Save the configuration and confirm that the ACL is enforced 5. Remove any broad or unnecessary ranges that could allow access from untrusted sources 6. Document any exceptions that must remain open, including justification and approval 7. Validate the changes by testing access from both allowed and disallowed networks to ensure enforcement is functioning as expected
