Hi Splunkers, in ES Content Update there's detection rule that requires a prebuild MLTK model that is formed by a search "ESCU - Baseline of Excessive AWS Instances Terminated by User - MLTK". And the search uses macro ec2_excessive_terminateinstances_mltk_input_filter , that can not be found neither in ESCU nor other apps. Is it more a Support case or someone may help with this macro?

Hi, so you say " _audit index is your friend for this" , but in the answer you'd proposed me the very first sentence is " It's already been determined that alarms/reports modifications are not being audited in _audit and _internal indexes." . 🙂 Thanks anyway!

Hi Splunkers, we need to monitor who, when, where and what was changed in macros, searches and so on. Internal index can answer to "who, when, where" (audit POST requests). Which is the right and preferred way to answer to "what" exactly was added or removed to/from the knowledge object during the change operation. P.S. We have to have this information in Splunk and correlate with _internal audit

I accept this message, because it has the most convenient approach - use of CLONE_SOURCETYPE. As a result I have the same data in a single index but in 2 sourcetype, one of them with masked data and restriction filter for guest role "sourcetype=data_masked"

I may use restrictions for the role - limit by sourcetype

Do I understand correctly, that using CLONE_SOURCETYPE will allow me to forward masked data to the same index but separate sourcetype and filter with restrictions of the role (sourcetype=clone) ? Will inputs work like this or do I need to use new index anyway as the source is the same?

Hi Splunkers, need to keep some sensitive data in index, but hide it for some roles. Is there any way to do this and if not - is it on plans?

Hi alonsocaio,
thank you for reply.
This is just a local name without any domain.
To be honest I did not examine all correlation searches on methods them correlate with intel tables, hence my question was brought up.
Also I'm in doubt it can compare lists with untypical field (not src, ip, user or other CIM-described field) .
So the idea with custom search that will parse data for a equality looks more appropriate to me as well.

Hi Splunkers,
We have an indicator of a phishing source from email headers - a PC name. We need to add it to a Threat Intel collection for ES.
I did not find an appropriate one to use. Should we create a custom list or would any of the pre-existing ollections work with it?

Hi Splunkers ,
any advice how to avoid mixng values in assets by entitymerge command?
I have 5 fileds marked as Multivalue (category, ip, mac) and sometimes it cause trouble like multiple assets mapped to all existing categories or multiple IP addresses, and thus incorrect notable events.
Do I understand correctly that I should mark fields as Multivalue if there might be several valuse (like 2 mac addresses for computer or several categories (router|network) ?

Hi @gcusello ,
everything may be custom - You can set index, source and sourcetype in inputs.conf on UF or DB Connect.
In this case you may\should have a big knowledge base and control everything.
I need something more simplistic like IP addresses or actual hostname of a source where logs were delivered from, is there's any option to track this?

Hi Splunkers,
we have centralized syslog collector.
Also many hosts deliver logs via UFs directly.
The same index may contain data delivered from UFs and from syslog inputs.
Also we have DB connectors and APIs.
Is it possible to divide data by type of input? Does Splunk have this kind of inspection?

HI,
sorry, I've figured out the problem - the reason of this is that at that day many of events for previous period was added to audit.
How should I handle this question correctly?

Hi Splunkers,
generally we use the approach to calculate license use for index by quering:
index="_internal" source="*metrics.log" group="per_index_thruput" series=myindex host=myindexer*
| stats sum(kb) as mb
| eval mb=mb/1024 .
But when we calculate it like a real raw size with
index=myindex
| eval mb=len(_raw)
| stats sum(mb) as mb
| eval mb=mb/1024/1024
we may have big difference, for example for one of indexes it is 4 Gb against 180mb!
Why is it so, please explain

Hi Mary,
thank you, that's a great example.
What I'm trying to say - with described add-on configuration you should not get any value for fields vendor_action and action on Search head, even if you have vendor_action in events.
I see you use condition AND match(lower('vendor_action') - does your 'vendor_action' field fulfilled with values?
