Abstract

The embodiment of the present invention discloses a device countermeasure method and device, which are applied to access controllers. The method includes: monitoring the detection message fed back by the access point AP in each virtual security domain VSD, and according to the detection message Generate device information of the wireless device, the device information includes device parameters; determine the device to be countered from the wireless device according to the configured counter strategy and the device information; Perform countermeasures, wherein the executing device is the top N sorted from large to small based on the device parameters of the device to be counteracted 1 APs, the N 1 is a positive integer. By applying the embodiment of the present invention, the countermeasure effect of the equipment is improved.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a device countermeasure method and device. Background technique [0002] like figure 1 As shown, the WLAN includes at least one AC (Access Controller, access controller), and each AC is responsible for managing the wireless connection of devices in at least one VSD (Virtual Security Domain, virtual security domain), wherein the VSDs can overlap , each AC is mounted with at least one AP (Access Point, access point) (AP includes: detection AP and common AP), the APs mounted under the AC are distributed in each VSD, common AP provides wireless access for the client Incoming services, detection APs perform tasks such as detection and countermeasures of each device in the local VSD. [0003] In order to ensure the security of clients accessing the WLAN, the process of countering illegal devices such as unauthorized APs and clients accessing the WLAN includes: [0004] 1. E...
