Security Model - 7-Minute SAP GOS Integrity Scan

Diagnostic-Only Architecture

This tool operates under strict diagnostic constraints designed for enterprise security review:

  • Zero Data Modification: Cannot update, delete, or create any SAP data
  • No Binary Access: Explicitly prohibited from accessing CLUSTD (binary data) column
  • Read-Only Functions Only: Limited to RFC_READ_TABLE and metadata functions
  • No Transport Capabilities: Cannot create, modify, or execute SAP transports
  • Reference Implementation Only: Not designed for automated remediation

Enterprise Security Compliance

What This Tool CANNOT Do:

  • Modify any SAP table entries
  • Access binary content from CLUSTD column
  • Execute ABAP code or custom function modules
  • Create or modify SAP objects
  • Access user personal data (PII)
  • Initiate data transfers or migrations
  • Perform cleanup or remediation operations

Authorization Requirements:

  • S_TABU_NAM: Table name access only (not S_TABU_DIS for content display)
  • RFC_READ_TABLE: Read-only table access function module
  • DDIF_FIELDINFO_GET: Metadata access for field definitions
  • EM_GET_NUMBER_OF_ENTRIES: Count entries without content access

Data Privacy Assurance

  • GDPR Safe: Extracts relationship metadata only, no personal data
  • Audit Compliant: All queries logged for compliance reporting
  • PII Protected: No access to personal identification information
  • Metadata Focused: Analyzes object relationships, not content values

Network & Connection Security

  • Standard RFC Protocol: Uses SAP's approved RFC communication channels
  • Encryption Support: Compatible with SAP's native RFC encryption
  • Parameter Validation: All RFC calls use validated parameters only
  • Connection Termination: All connections closed after diagnostic completion

Prohibited Operations Matrix

This diagnostic tool is explicitly designed to avoid:

  • ❌ Any write, update, or delete operations
  • ❌ Binary data extraction or processing
  • ❌ Transport request creation or modification
  • ❌ User data access beyond relationship metadata
  • ❌ Automated remediation or cleanup execution
  • ❌ Custom ABAP code execution
  • ❌ Direct database operations

This security model ensures the tool passes enterprise security and audit requirements while providing necessary diagnostic capabilities for risk assessment.
