    The access analyzer analyzes the policy and displays the findings of external access. You can adjust the trust policy based on the findings before saving the trust policy.

  6. (Optional) Expand each finding to review the finding details and validate access.

    You can select from the following types of findings:

    • All: indicates all findings for external access after the trust policy is modified.
    • New: indicates that a finding for new external access would be introduced after the trust policy is modified.
    • Resolved: indicates that an active finding for external access would be resolved after the trust policy is modified.
    • Archived: indicates that a finding for new external access would be automatically archived based on the archive rules after the trust policy is modified.
    • Existing: indicates that a finding for external access would remain unchanged after the trust policy is modified.

  7. Click OK.
