Detect CreditCard numbers in Logs

Elastic Observability Logs
1

Currently, we're running ELK-Stack and I would like to setup-configure detection & alerts for logs containing CreditCard numbers.

I did skim through certain ELK-modules, but couldn't find any suitable that can achieve the objective objective. Can anyone please suggest me on this

You could use queries or watchers with a regex for credit cards, this should work:

/([0-9]{13,16}|[0-9]{4}.[0-9]{4}.[0-9]{4}.[0-9]{4})/
