Azure Redis Cache Connection String Password
Detects Azure Cache for Redis connection string password patterns extracted from connection strings. This pattern is based on a Microsoft Purview built-in sensitive information type. Users already running Purview may prefer to enable the built-in SIT directly, or use this version as a starting point for customisation.

Known false positives
- Redis documentation with placeholder password values. Mitigation: Check for common placeholder patterns and documentation context.
- Non-Azure Redis passwords in similar format. Mitigation: Use Azure Redis specific keywords for differentiation.
