In this issue, the editor will bring you an example analysis of wireless network security in big data. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

There are many important IT resources in the enterprise network, such as OA server, ERP server and so on. Once these business hosts stop working or are attacked, it will directly affect the normal operation of the business and bring heavy losses. In the case of wired network, the security is still relatively reliable. At this stage, most enterprises provide wireless Internet access; as long as the client knows the wireless password, it can access the enterprise's local area network, resulting in security risks. The key point is that your wireless password is not secure:

Software such as aircrack can violently crack wireless passwords.

Once an employee installs software such as wifi keys, your wireless is public.

The separation of the guest network from the office network does not prevent visitors from connecting to the office network. (visitors can ask for a password directly, or access it through software such as wifi key)

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

Only allowed mac addresses can be connected to the office network.

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

After this binding, unauthorized devices (mac addresses) cannot access the office wireless even if they know the wireless password. This ensures the information security of the enterprise intranet. Taking the WSG Internet behavior Management Gateway as an example, some screenshots of related configurations are as follows:

1) VLAN partition

The office network and guest network are divided into different VLAN.

2) IP-mac binding

Register the office worker's mobile phone and computer for IP-MAC binding.

The office network segment is strictly restricted, and unbound devices can neither get IP nor access the Internet.

The above is the example of wireless network security in big data shared by the editor. If you happen to have similar doubts, you might as well refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
