What does FortiAnalyzer SIEM do with logs?

FortiAnalyzer SIEM plays a crucial role in managing log data by parsing, normalizing, and correlating logs. When logs are received from various Fortinet devices and other network components, they can be in different formats and contain a wealth of information. Parsing breaks down these logs into structured formats, making the data easier to understand. Normalization ensures that the data adheres to a common format, which simplifies analysis across different sources and types of logs.

Correlation is the next vital step, where FortiAnalyzer analyzes the parsed and normalized logs to identify patterns, anomalies, or relationships between events. This capability allows organizations to detect security incidents, generate alerts for abnormal activities, and improve incident response times. By integrating these processes, FortiAnalyzer provides a robust framework for effective security monitoring and compliance reporting.

The other options do not accurately represent the primary functions of FortiAnalyzer. While storage of logs is a feature, the focus of SIEM is heavily on analysis and actionable insights rather than mere storage. Deleting logs might be a part of log management policies but is not a function attributed to the SIEM's analytical capabilities. Generating performance reports is also part of FortiAnalyzer’s functionalities, but it is not the core purpose when dealing with logs
