How can you ensure proper log correlation between FortiAnalyzer and all connected devices?

Ensuring proper log correlation between FortiAnalyzer and all connected devices is crucial for effective monitoring and analysis of network activities. Using an NTP (Network Time Protocol) server to synchronize time across all devices is important because log entries are timestamped. Accurate timestamps allow for the correct sequencing of events across multiple devices, which is essential for understanding the timeline of incidents and troubleshooting.

When the logs from different devices are synchronized in time, it becomes much simpler to correlate events, detect anomalies, and perform security analysis. If logs are generated with inconsistent timestamps due to time drift among devices, it can lead to confusion and a lack of clarity in understanding the order of events, making incident response less effective.

Other options, while related to system configurations, do not contribute to proper log correlation. Using a dedicated firewall does not inherently solve time synchronization issues. Maintaining separate log files for each device could actually complicate the correlation process rather than facilitate it. Disabling device logging would prevent the generation of logs altogether, which directly undermines the purpose of log correlation. Thus, syncing with an NTP server is the most effective solution for ensuring cohesive and accurate logging across all connected devices.
