Discussion

OpenSSH on the ESXi host ships with a FIPS 140-2 validated cryptographic module that is enabled by default. For backward compatibility reasons, this can be disabled so this setting can be audited and corrected if necessary.

Check Content

From an ESXi shell, run the following command:

# esxcli system security fips140 ssh get

or

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

$esxcli = Get-EsxCli -v2
$esxcli.system.security.fips140.ssh.get.invoke()

Expected result:

Enabled: true

If the output does not match the expected result, this is a finding.

Fix Text

From an ESXi shell, run the following command:

# esxcli system security fips140 ssh set -e true

or

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

$esxcli = Get-EsxCli -v2
$arguments = $esxcli.system.security.fips140.ssh.set.CreateArgs()
$arguments.enable = $true
$esxcli.system.security.fips140.ssh.set.Invoke($arguments)
