Information

The vCenter Server must remove unauthorized port mirroring sessions on distributed switches.

GROUP ID: V-258965RULE ID: SV-258965r961863

The vSphere Distributed Virtual Switch can enable port mirroring sessions allowing traffic to be mirrored from one source to a destination. If port mirroring is configured unknowingly this could allow an attacker to observe network traffic of virtual machines.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

From the vSphere Client, go to "Networking".

Select a distributed switch >> Configure >> Settings >> Port Mirroring.

Select the unauthorized "Port Mirroring" session and click "Remove". Click "OK".
