Getting Data In

strip sensitive data before indexing

Hi all,

We run several tools in our environment for network inspection and the logging it provides logs things like NTLM creds, HTTP Basic Auth etc. We'd like to strip this data off before indexing, or at least 'sanitize' it so we dont index usernames/passwords. Can anyone point me in the right direction to solve this?

Example data:

{
"timestamp":"2018-04-04T09:00:08.085563-0600",
"flow_id":151014950299099,

"dest_port":443,

"tx_id":0,
"alert":{

"http":{
