Security method for operator access control of network management system
First Claim
1. A security method for operator access control of a network management system, the method comprising:
- performing an Internet Protocol (IP) filtering to determine whether or not an inputted Internet Protocol address of an external operator is a preset Internet Protocol address using one of either a Transmission Control Protocol/Internet protocol (TCP/IP) or a User Datagram Protocol/Internet protocol (UDP/IP); and
connecting the external operator to a communication system by either inputting an Identifier/Password or by setting communities upon a determination that the Internet Protocol address of the external operator is a preset Internet Protocol address.

Abstract
To access control without changing a presently used version of a system application protocol, an operator enters an ID and a password of the operator for user authentication, and, if the user authentication is successful, the operator will have access to an application layer of a system managed using either TCP/IP or UDP/IP. The application layer is adapted to be accessed using a security module to confirm whether or not an IP address of a terminal used by the operator is a preset IP address. In a network operating a version of a network management interface not equipped with a security function, the security deficiency of the system is alleviated by simply adding the security module without effecting a version upgrade process.
