Gateway verification can provide shared evidence to services. Preserve the decision's integrity across the internal network.
Evaluation approach
Prevent external clients from supplying trusted result headers. Bind evidence to account, request and target action.
Application example
Accept a verified header only through trusted paths. Alternative back-end routes must not bypass equivalent checks.
Limits and considerations
A gateway result does not replace object ownership checks.
Is there another route to the back end?
Internal or management paths may bypass the gateway. Review every entry point and demonstrate that external callers cannot forge the verified result.
Checks and decisions
- Strip external trust headers
- Review alternate routes
- Verify transaction binding
