SPLUNK TSTATS HOW TO

The Splunk SOAR (Phantom) hands-on workshop is designed to familiarise participants with how to respond to incidents, manage cases and artefacts, as well as automate your incident response and standard operating procedures. Prerequisites: Splunk Fundamentals 1 (highly recommended), Enterprise Security hands on workshop or some ES experience is also be recommended. Users will come away with a better understanding of how to build their own correlation searches in Splunk as well as how to customise their associated notable events to provide more immediate insights to their analysts The workshop leverages the popular Boss of the SOC (BOTS) dataset with hands-on exercises that build on one another. Users will gain familiarity with building correlation searches in Splunk, as well as introducing data models and the tstats command that can provide a user a method to further optimise their correlation searches. This is a modular, hands-on workshop designed to show participants how to leverage Splunk to develop their own correlation searches. Replay any dataset to Splunk Enterprise by using our replay.py tool or the UI.Sign up for one or multiple upcoming workshops:īuilding Correlation Searches with Splunk, hands on workshop

Initial Confidence and Impact is set by the analytic author. The Risk Score is calculated by the following formula: Risk Score = (Impact * Confidence/100). Registry modification in 'shutdownwithoutlogon' on $dest$ In that scenario filter of machine and users that can modify this registry is needed.

This windows feature may implement by administrator in some server where shutdown is critical. To successfully implement this search you need to be ingesting information on process that include the name of the Filesystem responsible for the changes from your endpoints into the Endpoint datamodel in the Processes and Registry node. List of fields required to use this analytic. It allows the user to filter out any results (false positives) without editing the SPL.

This analytic is to detect a suspicious registry modification to disable shutdown button on the logon user. Windows Disable Shutdown Button Through Registry
