Hi Ajay,
I manage to Redact data in my environment (after many days of looking for a solution) unfortunately there is no official guide\documentation provided by IBM :(.
What i have done is:
1. Installing firewall for Linux S-tap (default state 2)
2. Enabling Inspect Returned Data on the Collector and Restarting Inspection Engines.
3. The solution was eventually found by creating the correct Data Pattern in the Extrusion Rule.
I used this template ([0-9]{4})[0-9]{2} to create corresponding Regex for my masking needs, found it here:
https://www.ibm.com/support/pages/ibm-security-guardium-redact-action-does-not-work-regular-expressions-include-curly-braces-y-when-applied-database-servers-microsoft-windows
Also you may find what you need in this guide in the Data Pattern section:
https://www.ibm.com/docs/en/guardium/11.4?topic=actions-rule-definition-fields
Hope it helps.
Regards,
Roman.
