Log scrubbing

A process that removes, hides, or encrypts confidential data in log files.

The Explain card

Plain English
Log scrubbing removes, hides or encrypts confidential data inside log files so that logs remain useful for debugging and monitoring without becoming a second copy of your secrets.
Example
An AI application logs full prompts and responses for troubleshooting. A scrubbing step replaces API keys, passwords and personal details with placeholder tokens before the logs reach the central logging platform.
Why it matters
Logs are widely readable, long-lived and often shipped to third parties. Unscrubbed AI logs can quietly leak everything users typed, turning an observability tool into a breach.
Hook
Wipe the chalkboard before the next class walks in.
