The SIEM (Security Information and Event Management) plays a crucial role from the start of the lifecycle, handling the collection, processing, and analysis of data.
It centralizes information from various sources within the organization, such as system logs, firewalls, and external security data, then correlates these events to identify patterns and indicators of compromise (IOCs).
The SIEM automates threat detection using predefined rules, enabling immediate alerts to the SOC about ongoing incidents.
By deeply analyzing this data, the SIEM helps prioritize threats and provides valuable insights for investigations, while generating reports to track the evolution of incidents and vulnerabilities over time.
