Re: Custom IP Reputation

bbraun · ‎11-11-2019

Hi

My end goal is to create a custom IP reputation table that tracks successful and failed logins by IP address and assigns a numeric score as result. For every successful auth it increments the score by 2 and every fail it decrements the score by 1. Ideally we would want a ceiling of 20 and a floor of -20. I realize we would have to play with those thresholds but its a good start.

Schedule a saved search like this:

|tstats WHERE index=* FROM datamodel=Authentication count(eval(authentication.action=="failure")) AS subtractme count(eval(authentication.action=="success")) AS addme BY host
| inputlookup append=t YourReputationLookup.csv
| stats first(reputation) AS reputation, first(addme) AS addme, first(subtractme) AS subtractme BY host
| eval reputation = reputation + addme - subtractme
| table host reputation
| outputlookup YourReputationLookup.csv
