What is the function of trusted hosts in administrative access?

Trusted hosts function to restrict login access to specific IP addresses or subnets, enhancing security for administrative access. By allowing only designated IP addresses to connect to the management interface of a device, it reduces the risk of unauthorized access attempts. This is crucial in securing sensitive configurations and management functions from potential threats originating from untrusted locations.

For example, if a network administrator works from a specific office location with a fixed IP address, configuring that address as a trusted host allows them to log in without compromising security. This practice helps to mitigate risks associated with remote administration, such as brute-force attacks or unauthorized access from unknown devices. While device performance settings, data upload processes, and backup management are important aspects of network device administration, they do not directly relate to the security function provided by trusted hosts.
