Managing services
Overview
Service management allows you to manage the following types of services: FTP, Telnet, SSH, SFTP, HTTP and HTTPS.
You can enable or disable the services, modify HTTP and HTTPS port numbers, and associate the FTP, HTTP, or HTTPS service with an ACL to block illegal users.
FTP service
FTP is an application layer protocol for sharing files between server and client over a TCP/IP network.
Telnet service
Telnet is an application layer protocol that provides remote login and virtual terminal functions.
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
HTTP is used for transferring webpage information across the Internet. It is an
You can log in to the device by using the HTTP protocol with HTTP service enabled, accessing and controlling the device with
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.
•Defines certificate
