Reporting can be useful for audits where we need to provide specific reports to review.

Before Planning to add an SIEM devices, Usually a data analysis should be done where a complete chart of event chart should be created. this helps you to create reports and correlation alerts on SIEM. After preparing the data analysis report, usually we recommend to create a Critical assessment sheet from business and CISO which specifically says how critical is the device and impact of incident of specific device. This help you to segregate incidents and provide severity information.

On implementing SIEM make sure the devices connected are sending required logs which is mentioned on data analysis chart. Review EPS average / peek rate and usage of disk which helps you to track the storage usage. While integrating databases make sure only security events are being tracked. Create co-relation alerts and to the incidents.
