Explanation

Discovery Scan Types: FortiSIEM uses various scan types to discover devices on a network. Layer 2 (L2) Scan: An L2 scan discovers devices based on ARP tables and MAC address information from adjacent devices. Limitation: If a device is quiet (not actively communicating) and its entry is not present in the ARP table of adjacent devices, the L2 scan may miss it. Other Scan Types: CMDB Scan: Based on the existing Configuration Management Database (CMDB) entries. Range Scan: Scans a specified IP range for devices. Smart Scan: Uses a combination of methods to discover devices.
