What is a benefit of user entity behavior analysis (UEBA) over security information and event management (SIEM)?

User Entity Behavior Analysis (UEBA) is particularly adept at identifying anomalies in user behavior that may indicate security threats, such as credential theft or insider threats. One of the main benefits of UEBA over traditional Security Information and Event Management (SIEM) systems is its ability to analyze user behavior patterns over time, allowing it to spot unusual activities that deviate from normal behavior, even if those threats have not been previously defined or recognized.

In many cases, SIEMs rely heavily on predefined rules and signatures to detect threats, which can make them less effective at identifying novel or sophisticated attacks that do not match known patterns. This limitation can lead to missed detections in scenarios where an attacker uses legitimate credentials to access sensitive information, illustrating a gap in threat detection capabilities when it comes to unknown or advanced threats.

Given this context, the assertion that SIEMs struggle to detect unknown or advanced threats like credential theft was accurately recognized as a key distinction where UEBA offers enhanced capability.
