Study Notes
Logs and Log Management
- Logs serve as a purpose for investigating breaches and network analysis.
- Examining multiple logs when investigating a breach is important to gain a comprehensive understanding of the incident.
Log Analysis
- Log messages can help determine network activity, including who, what, when, and where.
- Centralized log storage is important for efficient log analysis and investigation.
FortiAnalyzer
- Log View in FortiAnalyzer allows users to view log messages.
- An A-DOM (Administrative Domain) in FortiAnalyzer is a grouping of devices and VLANs.
- A log group in FortiAnalyzer is a collection of logs from multiple devices.
- Log groups do not occupy additional disk space.
Log Content
- Request and response logs of primary and secondary PLC or RTU devices contain information about device interactions.
Log Analogies
- Logs are often described as the "black box" of a network, providing a record of events.
Fortinet Devices
- FortiAnalyzer provides logging, reporting, analytics, and automation for all on-fabric devices and endpoints.
- The single-pane-of-glass approach in FortiAnalyzer allows for efficient incident response and review.
