In case a relevant add-on is not present or even the Splunk add-on does not make the logs 100% CIM compliant it’s required to do this process manually following the guidelines provided by CIM add-on for each type of data. Where possible you should prefer to use add-ons built and supported by Splunk. You can check the same by navigating to details of the add-on: ![]() irrespective the format in which the device sent the data, Splunk can rename the fields, create new fields, extract new fields, assign tags, event types, create macros during the search time itself.įurther Splunkbase contains numerous add-ons for data parsing which make the data CIM compliant. Now, good thing is most of the recommendation and requirements of CIM can be fulfilled at search time i.e. Without making the data CIM compliant the ES use cases will simply not work as it would e looking for field names which are not there in the events. This is very critical that all log sources have been made CIM compliant, as all the use cases Splunk enterprise security ships with use the fields from CIM only. In such case for both Device A and Device B we need to create field alias or create a new field “src_ip” which contains the value of “Source_address” and “src_address” for device A and Device B respectively. For exampleĭevice A – Uses field name “Source_address” for IP of the machine which initiated the traffic.ĭevice B – Uses field name “src_address” for the sameĬIM – Cim suggests field name “src_ip” should be used for the same CIM is required so that logs coming from different devices can be normalized in same format and subsequently single search referring standard field names can be written to search and query data across various data sources. Not enough resource can have serious impact for ES performanceĬIM can be thought of as a model or set of guidelines or instructions regarding what field names should be used and what tags, eventtypes should be assigned to events when the data is being ingested and parsed by Splunk. Having enough CPU cores and RAM is very important for Splunk Enterprise security to run it’s numerous correlation searches and data model acceleration and summarization searches. In case there is heavy search load and/or huge data volume it’s recommended to further provision more resources. Splunk Enterprise Security documentation recommends minimum hardware specifications as below: Machine roleĪs mentioned in the table these are minimum Specifications mentioned. In the subsequent sections we will cover the most important aspects which needs to be taken care of while configuring Splunk Enterprise Security following industry best practices However, to leverage the value and power from this impressive solution it’s prudent to setup and configure the Splunk Enterprise Security properly. Splunk Enterprise Security along with Use case library provides an impressive 1000+ use cases which includes reports, dashboards and alerts. Further Splunk Enterprise Security now comes with built in Use Case library. ![]() It’s so powerful that Splunk + Splunk Enterprise Security have been leading the Gartner quadrant for SIEM solutions continuously for past many years, bypassing the traditional SIEM solution such as HPE ArcSight, IBM Qradar and the more recent solutions like Logrythm, Exabeam, ELK etc. ![]() Splunk Enterprise Security is the app which power the Splunk to work as full-fledged industry leading Security Incident and Event Management i.e. Splunk Enterprise Security is a premium and paid app from Splunk which is installed on top of Splunk Core i.e. ![]() Splunk Enterprise Security Configuration Best Practices
