SureLog SIEM Use Cases

Not all security information and event management (SIEM) use cases are equally important. The most important feature of SIEM is use cases. These are the samples of SIEM use cases and behaviors that SureLog can detect in your infrastructure.

SureLog Use Cases:

• Returns days where a user accessed  more  than  his  95th  percentile  number  of  assets
• Look for a user whose http to dns protocol ratio is %300 more than %95 of the other users for the last four-week ratio for 4th day of week
