Abstract

The invention discloses a method for quickly judging the legality of wireless access equipment in an industrial control environment. The specific steps of the method include step 1: the administrator sets the known wireless access equipment as legal wireless access equipment or illegal Wireless access device; Step 2: Receive the new wireless access device information sent by the wireless access device monitoring unit, write it into an industrial-grade large-capacity storage device, and confirm whether the wireless access device exists in the blacklist of the wireless access device. The MAC address information of the wireless access device is used to judge the legitimacy of the wireless access device; Step 3: If the MAC address information of the wireless access device does not exist in the blacklist of the wireless access device, then confirm the wireless hotspot connected to the wireless access device Whether it is an illegal wireless hotspot to judge the legitimacy of the wireless access device. Therefore, the present invention can not only solve the problem of legitimacy detection of wireless access equipment in the industrial control system environment, but also send out alarm, early warning and notification messages in time, and play an active and effective security protection role for the industrial control system network.

Description

technical field [0001] The invention belongs to the field of wireless communication security, in particular to a method for quickly judging the legality of wireless access equipment in an industrial control environment. Background technique [0002] With the continuous deepening of the integration of informatization and industrialization, industrial control systems have moved from stand-alone to interconnected, from closed to open, and from automation to intelligence. While productivity has increased dramatically, industrial control systems are facing increasing cybersecurity threats. In order to deal with these network security threats, the real-time production control area of ​​the industrial control system is usually divided into independent networks for physical isolation. However, with the development of communication technology, WIFI technology has been widely used by virtue of its own advantages. While bringing people a wide range of convenience, it has brought great...
