| On some systems, accounts with disabled passwords still allow access using rcp, remsh, or rlogin through equivalent remote hosts. All that is required is the remote host name and the user name match an entry in a hosts.equiv file and have a .rhosts file in the user directory. Using a shell called /bin/false or /dev/null (or an equivalent) will add a layered defense. Applicable, but permanent not-a-finding - There is only 1 local account on ESXi-v5 (root), which must never be disabled. All other accounts (excepting vpxuser which is automated by vCenter) are Active Directory. The root account login is locked in Lockdown Mode (a requirement). |
