Analysis of Illegal Terminal Bypass Blocking in Power Industry Marketing Scene Based on Network Topology and Result Estimation
Abstract— Because of the characteristics of wide-ranging points, diverse access modes and complex
network topology in power industry marketing site, precise blocking must be achieved when abnormal
terminals are blocked to ensure that blocking action only affects specific illegal access terminals. This
requires precise selection of blocking points, and wrong selection of blocking points may have a significant
impact on the normal business of the network. In order to solve this problem, this paper adopts the
construction of the power industry marketing field terminal access network topology map, pre-calculates the
blocking revenue and blocking cost of each blocking node in the attack graph, and then selects the blocking
with the least benefit of the blocking cost. The node implements accurate and effective illegal terminal access
path blocking by bypassing the access port, network redirection and other bypass blocking technologies. This
method can achieve accurate control and precise blocking of illegal terminals, and is more suitable for the
complex environment of the power industry business hall.
