AOS, when configured as a WLAN bridge, must not be configured to have any feature enabled that calls home to the vendor.

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. (Refer to SRG-NET-000131-RTR-000083.)

Verify the AOS configuration using the web interface:

1. Navigate to Configuration >> System >> More tab. 2. Expand "Phone Home ".

If "Phone Home" is enabled, this is a finding.

Configure AOS using the web interface:

1. Navigate to Configuration >> System >> More tab. 2. Expand "Phone Home". 3. Click the toggle button to disable "Phone Home". 4. Click Submit >> Pending Changes >> Deploy Changes.
