When do I need a SIEM system (typical use cases)?

The use of a SIEM system pays off for any company that relies on smooth IT operations. A SIEM analyses data and uncovers various suspicious processes in a system. A typical use case is, for example, a user logging into a network from different locations within a short period of time.

However, a SIEM does not only focus on analysing events. Numerous solutions now include "User and Entity Behaviour Analytics" (UEBA) to monitor user behaviour based on artificial intelligence. In this case, the SIEM creates behaviour profiles that can include network activities, logins and file access.

What advantages does a SIEM offer?

A SIEM provides an overview of security-relevant events in IT environments and helps to fulfil legal IT security requirements. Both the real-time reaction to threats and the subsequent detection of security events are possible. With the help of automated reports and targeted alerts, IT security personnel can react appropriately to various threats.
