Problems solved by technology

However, although these security standards provide important protection for the communication security of wireless networks, they are far from perfect, and they cannot reach the perfect state, which is determined by the complexity of network security mechanisms.

Embodiment Construction

[0011] It is realized through a wireless firewall, mainly using wireless network intrusion detection and prevention technology. The wireless firewall function acts on the second layer of OSI, that is, MAC layer 25 (MAC layer is the data connection layer, OSI includes Wi-Fi wireless network card 23, driver program 24, MAC layer 25, network layer 26 and layers above the network layer), A new type of wireless firewall architecture, such as figure 1 As shown, the wireless firewall includes an intrusion detection and intrusion prevention module 11, a first frame hook (Frame Hook) 21 and a second frame hook 22, the intrusion detection and intrusion prevention module 11 is located in the user space 1 of the system, and the first frame hook 21 Connect the kernel space 2 (Kernel Space) of the operating system and the user space (User Space) 1, one end of the first frame hook 21 is in the wireless network card driver 24 of the operating system kernel space 2, and the other end of the fi...

Abstract

The invention relates to a network security method based on a wireless firewall. In the method, the wireless firewall acts on an MAC (Media Access Control) layer of OSI (Open System Interconnection) and comprises an intrusion detection and prevention module, a first frame hook and a second frame hook, wherein, the intrusion detection and prevention module is positioned in a user space of a system; the first frame hook is connected with a kernel space and the user space of the operating system, one end of the first frame hook is arranged in a wireless LAN (local area network) card driver in the kernel space of the operating system, the other end of the first frame hook is arranged in the user space and is connected with the intrusion detection and prevention module, the first frame hook transfers a frame received by the wireless LAN card driver to the intrusion detection and prevention module, and then the frame is sent back to the driver through the frame hook or is deleted after being processed by the module; and one end of the second frame hook is arranged in the wireless LAN card driver in the kernel space of the operating system, and the other end of the second frame hook is arranged in the user space and is connected with a frame encapsulation module. By adopting the network security method, the hacker attack resistance can be strengthened and the availability of the wireless network is improved.

Description

technical field [0001] The invention relates to a wireless network firewall system, in particular to a network security method based on a wireless firewall, which belongs to the technical field of Wi-Fi, and its system framework can also be applied to other wireless technologies, such as Zigbee and WiMAX. Background technique [0002] The eternal theme of network communication development is to enable people to obtain network resources freely, and security guarantee is the key element and necessary condition to realize this goal. The lack of security guarantee will inevitably lead to illegal operation of the network and then affect the security of upper layer communication content. With the gradual maturity of Wi-Fi technology, its price is quite cheap, and its potential application fields are very extensive. At present, the main reason hindering the application of Wi-Fi in key fields is security risks, and security has become the bottleneck of Wi-Fi development. In order ...
