Logs aid development but create another exposure surface when they contain headers or personal data. Define production logging policy explicitly.
Evaluation approach
Exclude tokens, passwords and sensitive bodies. Check masking in error paths and third-party SDK output.
Application example
A request identifier and error class may be enough for a network investigation instead of the full Authorization header. Support should not require secrets.
Limits and considerations
Lowering log levels does not delete earlier or remotely transmitted copies.
How to verify masking
Success-path samples are insufficient. Timeouts, parsing failures and server rejections often produce more detailed output. Exercise those paths with test accounts and inspect for complete tokens, passwords or personal documents.
Checks and decisions
- Mask headers
- Review SDK logs
- Test release packages
