Key components of a SIEM system include:

Security Information Management (SIM):

This component involves the collection, normalization, and storage of security-related data from disparate sources such as logs, events, and alerts generated by network devices, servers, applications, and security controls.

Security Event Management (SEM):

SEM focuses on real-time monitoring and analysis of security events and alerts to identify suspicious or malicious activities. This involves the correlation of security data to detect patterns, anomalies, and potential security incidents.

Security Incident Response:

SIEM systems provide capabilities for incident detection, investigation, and response. When a security incident is detected, the SIEM can trigger automated response actions or alert security analysts for further investigation and remediation.

Log Management:

SIEM solutions often include log management capabilities for collecting, storing, and analyzing large volumes of log data generated by IT systems and applications. This helps organizations maintain compliance with regulatory requirements and facilitates forensic analysis during security investigations.

Compliance Reporting:

SIEM systems can generate reports and dashboards to provide insights into an organization’s security posture, compliance status, and trends in security incidents. This is essential for demonstrating compliance with industry regulations and standards.
