THIS IS A EXPERIMENTAL DETECTION
This detection has been marked experimental by the Splunk Threat Research team. This means we have not been able to test, simulate, or build datasets for this detection. Use at your own risk. This analytic is NOT supported.
The following anomaly will be generated when a new device is added to an account. Albeit not malicious, risk is set low, but should be monitored. This anomaly utilizes the legacy events from Okta.

The SPL above uses the following Macros:
okta_new_device_enrolled_on_account_filter is a empty macro by default. It allows the user to filter out any results (false positives) without editing the SPL.

How To Implement
This analytic is specific to Okta and requires Okta logs to be ingested.
Known False Positives
Tune the risk score as needed based on your organization.
Associated Analytic Story
|24.0||40||60||$user$ has added a new device to their account.|
The Risk Score is calculated by the following formula: Risk Score = (Impact * Confidence/100). Initial Confidence and Impact is set by the analytic author.
