SIEM System Use Cases

Working on LogRhythm - Cloud SIEM project. LogRhythm's SIEM solution combines enterprise log management, security analytics, user entity and behavioral analytics (UEBA), network traffic and behavioral analytics (NTBA) and security automation and orchestration. That integrated approach can make for efficient security operations, from threat detection to incident response.

Because SIEM is a core security infrastructure with access to data from across the enterprise, there are a large variety of SIEM use cases. Below are common SIEM use case examples, from traditional uses such as compliance, to cutting edge use cases such as insider threat detection and IoT security.
