Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment the present invention will be further described:

[0021] Such as figure 1 As shown, the embodiment of the present invention provides a method for quickly judging the legality of a wireless hotspot in an industrial control environment, wherein the specific steps of the method for quickly judging the legality of a wireless hotspot include:

[0022] Step 1: The administrator sets known wireless hotspots as legitimate wireless hotspots or illegal wireless hotspots, where legal wireless hotspots are recorded in the wireless hotspot white list, and illegal wireless hotspots are recorded in the wireless hotspot blacklist;

[0023] Step 2: Receive the new wireless hotspot information sent by the wireless hotspot monitoring unit, write it into an industrial-grade mass storage device, and determine whether the SSID and BSSID information of the wireless hotspot exists in the wireless hotspot blacklist or the w...

Abstract

The invention discloses a method for quickly judging the legitimacy of wireless hotspots in an industrial control environment. The specific steps of the method include Step 1: the administrator sets the wireless hotspot as a legal wireless hotspot and an illegal wireless hotspot; Step 2: receiving the new wireless hotspot information sent by the wireless hotspot monitoring unit, and writing it into an industrial-grade large-capacity storage device , for the administrator to read afterwards and determine whether the SSID and BSSID information of the wireless hotspot exists in the wireless hotspot blacklist or the wireless hotspot white list; Step 3: If the wireless hotspot does not exist in the wireless hotspot blacklist or the wireless The SSID and BSSID information of the hotspot verifies the legitimacy of the wireless hotspot by judging whether the signal strength of the wireless hotspot exceeds a preset threshold. Therefore, the present invention can not only solve the problem of legitimacy detection of wireless hotspots in the industrial control system environment, but also issue alarms, early warnings 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 hotspots 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 greater secur...
