Getting Data In

Anonymize data using regex transform

Hi Splunk experts,
I am using regex transform to mask data in splunk. But splunk only masks first occurence of string matched with that regex in 1 event.For example

[user]
REGEX = (?i)^(.*?)user\=\w+(.*)$
FORMAT = $1user=XXXXXXX$2
DEST_KEY = _raw

Sample event

2013-02-22 user=xyz hello user=abc

It will just mask user=xyz and will not touch user=abc.

Do we have any solution for this.

Thanks

I would personally look at using a sed command instead:

The following is not tested but it should give you an idea.

SEDCMD-user = s/user=(\w+)/user=xxxxx/g

...but SEDCMD is using regex. I really don't see the problem.

May b because I have already followed that route and implemented data masking and now i have to do all the work again using SED CMD 😞 .So looking for solution using regex only

It might be but why would you go for that route when SEDCMD exists?

So you mean it is not possible using regex transform?
