By default, if there is no password defined telnet access is not functional.

You could also create an ACL that denys all traffic.

conf t
line vty 0 15
 no password
conf t
access-list 1 deny any
line vty 0 15
 access-class 1 in

No password on a vty or no AAA config pretty much kills any remote telnet/ssh.
