Method and apparatus for implementing access control on web-based configuration pages using SNMP-based mechanism

摘要

A method enables user configuration of one or more feature parameters of a cable modem using a web page but permits a service operator to control this user configuration by specifying which of the one or more feature parameters a user can configure and/or view. According to an exemplary embodiment of the method, a web server executes an access control function prior to presenting a web page to a user to determine which of the one or more feature parameters are permitted to be viewed/configured by the user. Each configuration field on the web page is associated with an object identifier corresponding to a feature parameter defined in a feature management information base. For each of the one or more feature parameter object identifiers the access control function determines an appropriate access level to use by searching for an access policy that matches the object identifier associated with the configuration field on the web page. If found, the access control function returns one of several possible access levels to the web server associated with the configuration field.
