1.50 VCSA-80-000286

Information

The vCenter Server must have Mutual Challenge Handshake Authentication Protocol (CHAP) configured for vSAN Internet Small Computer System Interface (iSCSI) targets.

GROUP ID: V-258953RULE ID: SV-258953r961863

When enabled, vSphere performs bidirectional authentication of both the iSCSI target and host. When not authenticating both the iSCSI target and host, the potential exists for a man-in-the-middle attack in which an attacker might impersonate either side of the connection to steal data. Bidirectional authentication mitigates this risk.

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

Solution

From the vSphere Client, go to Host and Clusters.

Select a vSAN Enabled Cluster >> Configure >> vSAN >> iSCSI Target Service.

For each iSCSI target, select the item and click "Edit".

Change the "Authentication" field to "Mutual CHAP" and configure the incoming and outgoing users and secrets appropriately.
