Managing services

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.
HTTP service
The Hypertext Transfer Protocol (HTTP) is used for transferring web page information across the Internet.
It is an application-layer protocol in the TCP/IP protocol suite.
You can log in to the device using the HTTP protocol with HTTP service enabled, accessing and
controlling the device with Web-based network management.
HTTPS service
The Hypertext Transfer Protocol Secure (HTTPS) refers to the HTTP protocol that supports the Security
Socket Layer (SSL) protocol.
The SSL protocol of HTTPS enhances the security of the device in the following ways:
• Uses the SSL protocol to ensure the legal clients to access the device securely and prohibit the illegal
clients.
Encrypts the data exchanged between the HTTPS client and the device to ensure the data security
•
and integrity, thus realizing the security management of the device.
