To harden your ESXi 6.0 hosts, we disable the MOB service so that any attacker can’t get to the web browser and access the MOB of the ESXi host (ex: https://esxi01.lab.com/mob), this setting will disable one of the attack vectors of theESXi hosts in the environment.
to do this, you SSH into the ESXi host where you want to disable the mob service and perform the following commands
esxi01# vim-cmd proxysvc/remove_service "/mob" "httpsWithRedirect"
to verify if the mob service has been removed from the ESXi host, use the following command
esxi01# vim-cmd proxysvc/service_list
the above command will list all the services on the ESXi host, look for the service “/mob”, if you don’t see this service, then it has been removed. if it is still there, then you will have to perform the first command and reboot the ESXi host to disable the mob service from the host.
