lockdown mode and DCUI

can anyone elaborate on the risk of:

not enabling lockdown mode on your vsphere hosts
no disabling DCIU on your vsphere hosts

Please pitch your responses at management level and keep it low tech for someone new to vmware. Perhaps to put it into context of how it exposes the data on your guest virtual machines hosted on them hosts. Any for any security issues this raises, can you elaborate on the likelehood?

If someone has access to the physical server console, they could try and gain access.

Usually if you are co-hosting in a datacenter, and sharing with other companies, you may want to enable this function, to prevent unauthorized access to the login prompt.
