Overview
The service management module provides six types of services: FTP, Telnet, SSH, SFTP, HTTP and
HTTPS. You can enable or disable the services as needed. In this way, the performance and security of
the system can be enhanced, thus secure management of the device can be achieved.
The service management module also provides the function to modify HTTP and HTTPS port numbers,
and the function to associate the FTP, HTTP, or HTTPS service with an ACL, thus reducing attacks of
illegal users on these services.
FTP service
The File Transfer Protocol (FTP) is an application layer protocol for sharing files between server and
client over a TCP/IP network.
Telnet service
The Telnet protocol is an application layer protocol that provides remote login and virtual terminal
functions on the network.
SSH service
Secure Shell (SSH) offers an approach to securely logging in to a remote device. By encryption and
strong authentication, it protects devices against attacks such as IP spoofing and plain text password
interception.
SFTP service
The secure file transfer protocol (SFTP) is a new feature in SSH2.0. SFTP uses the SSH connection to
provide secure data transfer. The device can serve as the SFTP server, allowing a remote user to log in
to the SFTP server for secure file management and transfer. The device can also serve as an SFTP
client, enabling a user to login from the device to a remote device for secure file transfer.
