Document conventions Introduction
Logging and reporting
The FortiGate unit supports logging for various categories of traffic and configuration
changes. You can configure logging to:
• report traffic that connects to the firewall,
• report network services used,
• report traffic that was permitted by firewall policies,
• report traffic that was denied by firewall policies,
• report events such as configuration changes and other management events,
IPSec tunnel negotiation, virus detection, attacks, and web page blocking,
• report attacks detected by the IPS,
• send alert email to system administrators to report virus incidents, intrusions, and
firewall or VPN events or violations.
Logs can be sent to a remote syslog server or a WebTrends NetIQ Security Reporting
Center and Firewall Suite server using the WebTrends enhanced log format. Some
models can also save logs to an optional internal hard drive. If a hard drive is not
installed, you can configure most FortiGate units to log the most recent events and
attacks detected by the IPS to the system memory.
