UBA or User Behavior Analytics and is a threat detection analysis technology that uses AI to understand how users normally behave and then find anomalous activities, which deviate from their normal behavior and may be indicative of a threat. For this scenario, the SIEM will first learn what is normal behavior then when a baseline is created, it will know if any of the logins are malicious. Likely determined by when and where the logins are occurring and if it's different from the baseline. This should hopefully reduce the amount of alerts occurring.
