Fix Recommendation

From the vSphere Web Client select the ESXi Host and go to Configure >> Storage >> Storage Adapters >> Select the iSCSI adapter >> Properties >> Authentication and click the Edit button. Set Authentication method to “Use bidirectional CHAP” and enter a unique secret for each traffic flow direction.

or

From a PowerCLI command prompt while connected to the ESXi host run the following command:

Get-VMHost | Get-VMHostHba | Where {$_.Type -eq "iscsi"} | Set-VMHostHba -ChapType Required -ChapName "chapname" -ChapPassword "password" -MutualChapEnabled $true -MutualChapName "mutualchapname" -MutualChapPassword "mutualpassword"

Check Contents

From the vSphere Web Client select the ESXi Host and go to Configure >> Storage >> Storage Adapters >> Select the iSCSI adapter >> Properties >> Authentication method and view the CHAP configuration and verify CHAP is "Required" for target and host authentication.

or

From a PowerCLI command prompt while connected to the ESXi host run the following command:

Get-VMHost | Get-VMHostHba | Where {$_.Type -eq "iscsi"} | Select AuthenticationProperties -ExpandProperty AuthenticationProperties

If iSCSI is not used, this is not a finding.

If iSCSI is used and CHAP is not set to "Required" for both the target and host, this is a finding.

If iSCSI is used and unique CHAP secrets are not used for each host, this is a finding.
