Security Information and Event Management SIEM is the gold standard of modern detection, analytics, and response. SIEM software utilizes multiple data points as well as threat intelligence feeds. SIEM falls into two directions: Security Information Management (SIM) and Security Event Management (SEM). The first involves long-term storage, analysis and reporting of log data. The second concerns real-time monitoring of events, alerts etc. As a combination of SIM and SEM, SIEM represents a complex solution protecting enterprise data, providing real-time analysis of security alerts generated by network hardware and applications and early warning of any cybersecurity-related suspicious activity or misconduct.
