| Description |
|---|
| 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. |
| ℹ️ Check |
|---|
| 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 |
|---|
| 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) |
