Security information and event management (SIEM), which combines security information management (SIM) and security event management (SEM), provides real-time event monitoring and evaluation as well as tracking and recording of security data for regulatory or auditing needs. SIEM is a security tool that aids companies in identifying possible security flaws prior to them having an opportunity to disrupt daily operations. For security and compliance management applications, it uncovers user behavior irregularities and employs ai to automate a large number of manual operations related to threat identification and event response.
