This search is specific to Okta and requires Okta logs are being ingested in your Splunk deployment.
Kill Chain Phase
Known False Positives
Users in your enviornment may legitmately be travelling and loggin in from different locations. This search is useful for those users that should not be travelling for some reason, such as the COVID-19 pandemic. The search also relies on the geographical information being populated in the Okta logs. It is also possible that a connection from another region may be attributed to a login from a remote VPN endpoint.
