What Is SIEM?

The basic functionality behind the SIEM tool is to collect data from various sources, analyze it in real-time, and then generate a report.

SIEM has become critical in today’s time.
SIEM software collects the data from the host system and security devices and gathers them on a centralized server. The data is then segregated into different categories, based on the severity of the threat ( failed logins, malware activity, or firewall intrusion)
Threat alerts are then generated based on the potential of the issue.
