IPv6 환경에서 호스트 탐색 및 네트워크 접속 차단 에이전트 시스템

Abstract

As IPv4 addresses are exhausting, the use of IPv6 addresses is increasing. IPv6 environment provides address auto-configuration function. If addresses are allocated to each host automatically, network management system has difficulty in inspecting every IP of all devices and keeping the relevant informations. Also, as IP addresses are configured automatically, problems such as malicious users accessing network devices with no restriction can occur. To solve these problems, managing and blocking of malicious user is necessary. In this paper, we suggest agent system for searching of host computer and blocking network access which manages and protects the major network resources efficiently by searching host and blocking unauthorized host access to network in IPv6 environment. According to the test results of function of this agent system in IPv6 environment, we have checked that this system performs searching and blocking function normally.
