How Does SIEM Work?
SIEM tools are VERY important part of your NETWORK: they aggregate data from multiple systems and analyze that data to catch abnormal behavior or potential cyberattacks. SIEM tools provide a central place to collect events and alerts.
Security Information and Event Management (SIEM) is a solution that aggregates and analyzes activity from many different resources across your entire IT infrastructure.
SIEM collects security data from network devices, servers, domain controllers, and more. SIEM stores, normalizes, aggregates, and applies analytics to that data to discover trends, detect threats, and enable organizations to investigate any alerts.
SIEM has two primary capabilities to an Incident Response team:
- Reporting and forensics about security incidents
- Alerts based on analytics that match a certain rule set, indicating a security issue
At its core, SIEM is a data aggregator, search, and reporting system. SIEM gathers immense amounts of data from your entire networked environment, consolidates and makes that data human accessible. With the data categorized and laid out at your fingertips, you can research data security breaches with as much detail as needed.
The SIEM include
- Basic security monitoring
- Advanced threat detection
- Forensics & incident response
- Log collection
