The protocol that the network administrator should ensure is enabled on the router to securely connect from within the office is SSH (Secure Shell).
SSH is a cryptographic network protocol that provides secure communication between network devices, allowing data to be exchanged securely over an unsecured network. It is commonly used to remotely access and manage network devices, such as routers and switches.
RDP (Remote Desktop Protocol) is a protocol that allows a user to connect to a remote computer and control it as if they were sitting in front of it. RDP is commonly used to provide remote access to desktops and servers. However, it is not recommended to use RDP to connect to routers and switches as it is not as secure as SSH.
TFTP (Trivial File Transfer Protocol) is a simple file transfer protocol that is commonly used for transferring firmware and configuration files to network devices. However, TFTP does not provide any security mechanisms, and it is not recommended to use it to connect to routers.
HTTP (Hypertext Transfer Protocol) is a protocol used to transfer data over the World Wide Web. HTTP is not a secure protocol, and it is not recommended to use it to connect to network devices, as it would expose sensitive information to potential attackers.
In summary, SSH is the recommended protocol to use when connecting to routers securely, as it provides encryption and authentication mechanisms to ensure secure communication.
