If you have been using a SIEM tool for quite a time, you will know that it can turn out to be a powerful security tool, if appropriately deployed. In your organization’s network, network devices such as IDS/IPS, firewalls, and routers generate a plethora of log data. Like these devices, there are many sources of data for a SIEM solution. The first barrier a SIEM encounters is normalizing the log data before it can detect and alert your team.
If your SIEM solution is configured correctly, it will filter through irrelevant log data to allow your security team to focus on essential and high-risk alerts. Correlation rules play a crucial role in the configuration of a SIEM platform. In this article, we explore what correlation rules are and how you can create your organization-specific correlation rules on Logsign SIEM.
