Hi All,

I have a Rapid Deployment security policy, with learn, alarm and block settings enabled for Data Guard as well.

But when i try to access the application, credit card number is not getting masked.

Any suggestions what else I might be missing ?

Big-IP version: 13.1.1

Hi,

So you confirm that “Data Guard” and “Credit Card Numbers” are enabled in Security ›› Application Security \>\> Data Guard.

Then in “Security ›› Application Security : Policy Building : Learning and Blocking Settings” in advanced mode you can see " Data Guard " at the end of the page. you must set this settings to block.

Last point you confirm that your policy is in blockind mode (Security ›› Application Security : Security Policies : Policies List)
