Method and device for managing network external connection

Abstract

The invention discloses a method and a device for managing network external connection. The method includes: S1: detecting an access network data packet flowing through a network card; S2: obtaining standard service data and broadcast data of an access device when the device access is detected; S3: judging whether the access device is an illegal external connection device according to the standardservice data and broadcast data of the access device; S4: when the access device is an illegal external connection device, isolating the access device from the network. The invention can judge the illegal external connection device timely, accurately and effectively, control the illegal external connection device, effectively solve the illegal external connection device accessing the internal network, facilitate the management of the internal network, and ensure the safety of internal data information at the same time. In addition, the network position of each terminal can be accurately located, and the data transmission between the internal network terminal and the external network terminal and between the secure terminal and the non-secure terminal can be effectively controlled to ensure the security of the intranet data.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a method and device for managing network outreach. Background technique [0002] Computer network refers to the connection of multiple computers with independent functions in different geographical locations and their external devices through communication lines. Under the management and coordination of network operating systems, network management software and network communication protocols, resource sharing and communication are realized. A computer system for information transfer. In order to ensure its internal information security, enterprises or institutions prevent internal terminals from connecting to the external network and external terminals from connecting to the internal network. [0003] In the prior art, enterprises or institutions need to spend a certain amount of money to purchase products such as hardware firewalls, install them between the network in...

AI Technical Summary

Problems solved by technology

This mode of operation needs to install hardware equipment at a specified location, the operation process is complicated, requires high hardware costs, and the later maintenance costs are high

[0004] At the same time, many smart devices such as mobile phones can access the internal network at will, making it difficult to manage internal network devices, and even build a WiFi network through internal network devices, which not only increases the difficulty of management again, but also puts internal data information at risk
