guardium://CREDIT_CARD pattern test does not use the Luhn algorithm when using redact policy action in Guardium.

Troubleshooting


Problem

You set a policy rule with REDACT action and guardium://CREDIT_CARD pattern test. You expect this to only mask genuine credit card numbers based on the Luhn algorithm. When inspecting the returned data for the traffic affected by this rule, all random 16 digit strings are redacted, not just genuine credit card numbers.
