A management system configured to manage device information responds, if an acquisition request for device information is received from an information processing terminal, to the information processing terminal with information for displaying the device information and script information including a command to cause the information processing terminal to check whether access to a web server implemented on the device is permitted. The information processing terminal is configured to, if the access to the web server implemented on the device is not permitted due to execution of the command included in the script information, be restricted from accessing the web server implemented on the device.
