What is an alternate method of log resolution if not using FortiAnalyzer?

The correct answer highlights the capability of FortiGates to resolve IP addresses directly, which can serve as a practical alternative to using FortiAnalyzer for log resolution. When FortiGates are configured to resolve IPs, they can translate those IP addresses into hostnames, providing contextual information that simplifies log analysis. This method allows administrators to quickly identify endpoints associated with recorded events, thus enhancing the comprehension of log entries without the intermediary of FortiAnalyzer.

Using FortiGates for IP resolution is often a straightforward approach, especially in smaller environments where the infrastructure may not warrant the use of a dedicated log analysis solution like FortiAnalyzer. Additionally, this method can be beneficial for immediate troubleshooting, as it streamlines the workflow of diagnosing issues in real-time.

Other methods, while viable, may involve additional overhead or complexity. Custom logging scripts could require substantial development and ongoing maintenance. Leveraging cloud services introduces dependencies on external solutions, which may not align with organizational policies regarding data security and compliance. Implementing third-party log analyzers might necessitate integration efforts and cost considerations, and it also means relying on external systems for critical log data analysis.
