  • Schedules You schedule the frequency of the audit and what checks are to be performed during each scan. For this lab and test IoT device, I have selected the recurrence of Monthly and covering medium, high, and critical checks I wish to have run.

  • Action Tasks
    Based on audits performed, there may be various audit action tasks.

  • Finding Suppressions
    Allow you to turn off findings related to a resource for a defined period of time until the resource is fixed, or indefinitely due to some exception.

Detect

  • Alarms
    When a device behavior anomaly is detected.

  • Security Profiles:
    Security Profiles define how your devices should behave and specify an alert mechanism for anomalies. Security Profiles are attached to one or more things.

For this example, I am going to create a new ML anomaly detection profile.
