Binary messages are not secure merely because they are harder to read. Establish identity, transport protection and method authorization explicitly.
Evaluation approach
Map service methods to permissions. Mask credentials in metadata logs and define timeouts.
Application example
A document method must verify ownership server-side even when the client code is protected.
Limits and considerations
A Protobuf schema does not establish source authenticity or business authority.
How much error detail is necessary?
Clients may only need to know whether retrying is appropriate. Keep internal addresses and stack traces in controlled diagnostics rather than external responses.
Checks and decisions
- Define method permissions
- Mask metadata
- Test interruption
