SRG-OS-99999-ESXI5-000141 - The system must enable bidirectional CHAP authentication for iSCSI traffic.

Information

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

Solution

In the vSphere Client, select the host, and then choose: Configuration >> Storage Adaptors >> iSCSI Initiator Properties >> CHAP >> CHAP (Target Authenticates Host). Select 'Use Chap', and configure the 'Name' and 'Secret' options.
