(c) Precautions for program registration via FTP
1) Login user setting
The C Controller module supports the basic authentication (account setting)
by use of the user name and password, but it restricts users and C Controller
module setting operation and does not completely prevent illegal access from
the outside.
2) When security against illegal access from outside is needed
Take measures at user's discretion when it is necessary to secure the safety of
the C Controller module against illegal access from outside.
