NIX Login Dashboard with Success, Failed and Sudo activity

Dashboards

Description

Submitted by thall

Description: Built this dashboard to display login activity for my *nix host devices.  At the top you have a box called “Filter” that allows you to insert search parameters in the base search (ex: user=thall).  Each panel has it’s own "TimeRangePicker" and a "Multiselect input" which allows you to decide what fields to add to the output (by default I start with “user” except on the "Sudo Activity" where "src_user" is included). All of *nix data goes into an index called "nix" and you will need to adjust the 3 searches that powers each panel to your environment.  This dashboard has been built around field extractions that are found in the Splunk Add-on for Unix and Linux. Tested against both Ubuntu Server and CentOS.  I did run into an issue with Ubuntu server data collection where the Splunk Add-on for Unix and Linux by default does not have a "props.conf" stanza for auth.log (/var/log/auth.log).  In my environment I created a "props.conf" in the local folder of the Splunk Add-on for Unix and Linux (Splunk_TA_nix) that gets deployed from my deployment-server (Folder location - $SPLUNK_HOME/etc/deployment-apps/Splunk_TA_nix/local) with the following: [source::....auth.log] sourcetype = syslog This allows "auth.log" to use the search time field extractions in the Splunk Add-on for Unix and Linux.  If you are not using a deployment server you will need to make changes on each UF adding that "props.conf" file under $SPLUNK_HOME/etc/apps/Splunk_TA_nix/local. Another issue I ran into was around the "app" field not allowing me to filter down on just the "ssh" value (app=ssh) without keywords like "Accepted"  A workaround is to go on your Search Head or Indexer and under the local folder of Splunk_TA_nix located in $SPLUNK_HOME/etc/apps, create a file called "fields.conf" with the following: [app] INDEXED_VALUE = false Add-on's required: Splunk Add-on for Unix & Linux - https://splunkbase.splunk.com/app/833/ Dashboard:
