The vCenter server must disable SNMPv1/2 receivers.

SNMPv3 supports commercial-grade security, including authentication, authorization, access control, and privacy. Previous versions of the protocol contained well-known security weaknesses that were easily exploited. Therefore, SNMPv1/2 receivers must be disabled, while SNMPv3 is configured in another control. vCenter exposes SNMP v1/2 in the UI and SNMPv3 in the CLI.

From the vSphere Client, go to Host and Clusters.

Select a vCenter Server >> Configure >> Settings >> General.

Click "Edit".

On the "SNMP receivers" tab, note the presence of any enabled receiver.

If there are any enabled receivers, this is a finding.

From the vSphere Client, go to Host and Clusters.

Select a vCenter Server >> Configure >> Settings >> General.

Click "Edit".

On the "SNMP receivers" tab, ensure all receivers are disabled.
