Which option must a FortiSIEM administrator configure to restrict network administrator searches to only firewall devices?

To restrict network administrator searches to only firewall devices in FortiSIEM, configuring Data Conditions is essential. Data Conditions allow the administrator to specify criteria that filter the types of devices or data sets that are included in searches or reports.

By setting Data Conditions specifically to match only firewall devices, an administrator can ensure that the search results will only reflect data from those devices. This is particularly important in environments where various types of network devices are managed, as it allows for focused and relevant searches that enhance efficiency and reduce noise in the results.

The other options, while related to administration and configuration, do not specifically address the requirement to restrict searches to particular device types. CMDB Report Conditions are generally used for implementing conditions in reports and might not filter searches directly. UI Access pertains to the user interface permissions and does not relate directly to device-specific search filtering. Audit Settings involve tracking and logging administrative actions but do not affect the search parameters.

Thus, by utilizing Data Conditions, FortiSIEM administrators can efficiently limit search results to only relevant firewall devices, facilitating better data management and analysis.
