UniFi Site Manager WAN external IP geographic deviation

Back


Id	9c0a7304-287e-f1b2-8b4f-c7444b8511ea
Rulename	UniFi Site Manager: WAN external IP geographic deviation
Description	Sites where the WAN external IP changed ASN or ISP within the last 30 days. Routine DHCP renewal stays within the same ISP; an ASN/ISP change suggests provider switch, BGP hijack, or routing anomaly that warrants verification.
Tactics	Reconnaissance
Techniques	T1590
Required data connectors	UniFiSiteManagerConnectorDefinition
Kind	HuntingQuery
Source Uri	https://github.com/Azure/Azure-Sentinel/blob/master/Solutions/UniFi Site Manager (CCF)/Hunting Queries/UniFiCloudWANIPGeoDeviation.yaml
Version	1.0.0
Arm template	9c0a7304-287e-f1b2-8b4f-c7444b8511ea.json
