Identify potentially exposed employees using Wi-Fi access logs from Mist Systems.

1. Set up the Contact Tracing Wi-Fi properties.
   • By default, the asset data is available in the Computer table [cmdb_ci_computer]. If you are using a different table, specify it using the sn_imt_tracing.wifi_client_table property.
   • Ensure that the MAC address is populated in the mac_address field in the table that has the asset data.
   For more information, see System properties for tracing systems in Emergency Exposure Management.
2. Set up the Contact Tracing BLE properties.
   • By default, the asset data is available in the Wearable Technology [cmdb_ci_wearable] table. If you are using a different table, specify it using the sn_imt_tracing.wifi_ble_client_table property.
   • Ensure that the MAC address is populated in the mac_address field in the table that has the asset data.

   Note: The Wearable Technology [cmdb_ci_wearable] table is installed with the CMDB CI Class Models application available on ServiceNow Store. For more information, see CMDB CI Class Models.
