Security and Compliance Material Review for Data Masking: Permissions and Data Isolation

Data processed in this category originates primarily from enterprise databases, data dictionaries, self-developed masking tools, and access approval

Data Characteristics of This Category

Data processed in this category originates primarily from enterprise databases, data dictionaries, self-developed masking tools, and access approval systems. It is updated per project batch or single task. Daily output documents include masking plans, field mapping tables, masking verification reports, and approval records. Data fields include sensitive information identifiers, original data content, masking rule configurations, verification results, and approval statuses. There are no fixed standard units, and configurations are adjusted flexibly based on the data types involved in the project.

Constraints on Permissions and Data Isolation

Data sources for this category are scattered, covering databases, data dictionaries, masking tools, and access approval systems. Permissions and data isolation must cover access permission verification for all data access channels. Following the per-project batch update rhythm, permission configurations must support quick adjustment and revocation of permissions per project. Documents containing sensitive information identifiers, original data content, and approval records require strict layered setting of operation scopes for view, edit, and approval roles. Fields containing sensitive information and masking rules must ensure only authorized personnel can access original sensitive data and complete configuration items.

Configuration Guidelines

This configuration rule applies to FastGPT v4.17.0.

Configuration ItemRecommended SettingRationale
teamId binding ruleOnly associate data sources and documents from the current projectMatch the per-project batch update data characteristics, isolate masking data across different projects
teamId permission checkEnable teamId verification for interface accessEnsure only authorized services can call masking processing interfaces
Member role configurationDivided into three categories: data view, rule configuration, approval and verificationMatch the layered operation requirements of documents, prevent unauthorized access
Sensitive data access logsRetain for 30 daysMeet log retention requirements for compliance audits
tmbId call permissionOnly bind the tmbId of the specified applicationLimit the scope of callers for masked data, prevent unauthorized applications from accessing

Three Common Misconfigurations

  • Symptom: Unable to open the team management page, or view team member operation records. Cause: Administrator role permissions for the corresponding teamId are not configured, no access authorization entry.
  • Symptom: Cross-team application calls to the masking interface return a permission denied error. Cause: The caller has not bound a dedicated tmbId, or the tmbId does not match the teamId of the masked data. The system blocks unauthorized requests.
  • Symptom: Masking rules for sensitive fields are modified by unauthorized personnel. Cause: Member role permissions are not set in layers, and regular members are assigned rule configuration permissions.

How to Verify Successful Configuration

  • Enter the team management interface, check whether the data sources bound to the current teamId match the data sources of the currently processed project.
  • Initiate a masking interface call with a preset tmbId parameter, verify that the interface can complete the masking process normally and return results.
  • View the member role configuration list, confirm that the operation permissions of each role match the preset layered rules.
  • Export the sensitive data access logs, confirm that the log recording scope meets compliance audit requirements.
