Example Analysis of Wireless Network Security in Big Data

There are many important IT resources within the enterprise network, such as OA servers, ERP servers, etc. Once these business hosts stop working or are attacked, they will directly affect the normal operation of the business and cause heavy losses. In the case of wired networks, security is relatively reliable. Now, almost all enterprises provide wireless Internet access. Clients only need to know the wireless password to connect to the enterprise LAN, which may bring security risks. The key point is that your wireless password is not secure: software such as

1. aircrack can brute force crack the wireless password.
   

2. #Once an employee installs software such as a wifi key, your wireless connection is open to the public.

3. The separation of the guest network and the office network does not prevent guests from connecting to the office network. (Visitors can directly ask for the password, or access through software such as wifi keys)
   

The final solution to this problem lies in MAC address binding:

1. Only allowed mac addresses can access the office network.
   

2. The guest network is in a separate VLAN and cannot access the corporate intranet.

Even if the unauthorized device (mac address) knows the wireless password, it will not be able to access the office wireless network after binding. This ensures the information security of the corporate intranet. Taking the WSG Internet Behavior Management Gateway as an example, some relevant configuration screenshots are as follows:

1) VLAN Division

The office network and the guest network are divided into different VLANs.

2) IP-mac binding

Register the mobile phone and computer of the office staff and perform IP-MAC binding.

Strict restrictions are placed on the office network segment. Unbound devices can neither obtain an IP nor access the Internet.
