After collecting and correlating security events into meaningful insights, these records must be stored for future analysis. A good SIEM system provides long-term storage capabilities that allow professionals to review past events logs when needed – which is critical when assessing threat trends or determining if any past actions could have led to possible vulnerabilities

Step 4: Threat Detection
This step marks one of the most critical functions of a SIEM solution – detecting potential threats in real-time. The system relies on machine learning algorithms capable of analyzing massive amounts of incoming signals instantaneously to detect anomalies worthy of further investigation by channeling them through its filtering framework automatically.

Step 5: Incident Response
After detecting potential issues, SIEM must alert security professionals to prompt incident response. System alerts appear in a unified dashboard often containing detailed data, enabling efficient investigation and quick decision making to stop attacks from attacking or limit the destruction, the breach may cause.

Step 6: Compliance and Regulation Management
With ever-changing regulations, organizations can stay ahead of maintaining compliance by utilizing a comprehensive SIEM solution that ensures that all essential security requirements are met, with pre-configured reports available at all times. By this way SOX, HIPAA, and PCI compliance officials can help safeguard sensitive data.
