Description
Call home services will routinely send data such as configuration and diagnostic information to the vendor for routine or emergency analysis and troubleshooting. There is a risk that transmission of sensitive data sent to unauthorized persons could result in data loss or downtime due to an attack.
ℹ️ Check
Verify the ACI configuration under Admin >> External Data Collectors >> monitoring Destinations >> smart callhome/callhome is not setup, and that no Intersight configuration is setup at System >> System Settings >> Intersight Connectivity. If the Call Home feature is configured to send messages to unauthorized individuals such as Cisco TAC, this is a finding.
✔️ Fix
Disable the Call Home feature: 1. Navigate to Admin >> External Data Collectors >> monitoring Destinations >> smart callhome. 2. In the General tab, set the Admin State to "Off". 3. Click "Save".
