User behavior analytics (UBA) is the tracking, collecting and assessing of user data and activities using monitoring systems.
UBA technologies analyze historical data logs -- including network and authentication logs collected and stored in log management and SIEM systems -- to identify patterns of traffic caused by user behaviors, both normal and malicious. UBA systems are primarily intended to provide cybersecurity teams with actionable insights. While UBA systems don't take action based on their findings, they can be configured to automatically adjust the difficulty of authenticating users who show anomalous behavior.
