What should be checked if a report is generating abnormal usernames?

When investigating the generation of abnormal usernames in reports, it's essential to check the user obfuscate setting in the advanced report settings. This setting is designed to provide an additional layer of security by obscuring sensitive information, including usernames, in the reports generated by FortiAnalyzer. If this setting is improperly configured or not utilized, it may lead to irregularities in the way usernames are displayed or reported, potentially causing confusion or revealing information that should remain private. Therefore, checking this setting is critical to ensure that the usernames are being handled appropriately in accordance with security and privacy policies.

The user obfuscate setting directly addresses how usernames are represented in reports, making it the most relevant factor in this scenario. Other factors, such as logging levels and user account status, while important in their own contexts, do not directly pertain to the specific issue of abnormal usernames appearing in reports. This demonstrates the importance of understanding how reporting features work and the settings that influence them within FortiAnalyzer.
