Design and Realization of Terminal Network Access Control System in Meteorological Industry
The rapid development of the meteorological information network promotes the continuous increase of the types and quantities of equipment connected to the meteorological internal network,which poses new challenges to the traditional network equipment access management.At this stage,the number of network access devices in the Meteorological Intranet office area exceeds 7 000.It is difficult to sort out the types and quantities of online devices,and illegal occupation of network resources occurs from time to time.Since it is difficult to determine the legitimacy of the access device,it cannot be discovered and blocked immediately after illegal access to the device,which poses a threat to the security of business systems and meteorological data.There may be malicious programs running on the network equipment,which may have a significant impact on the security of other equipment after connecting to the meteorological network.Traditional control technology needs to maintain local data information,and there is a risk of data accuracy lag and leakage.Based on solving the above problems,we design and implement a clientless terminal network access control system that meets the needs of meteorological networks.Through data sharing with China Meteorological Administration unified trust service system and terminal security management system,the automatic update and maintenance of identity authentication information is realized.At the same time,it promotes the wide application of terminal security management software in meteorological parks,timely discovers and blocks the access of illegal devices,and eliminates potential security risks.
