Wireless access to LAN or Internet is now a reality. However, at present, it is not so easy to achieve efficient and secure access. After all, it is much more complicated to connect to LAN or Internet through wireless mode than by using twisted pair mode to access LAN or Internet.

With the continuous maturity of wireless networks, the security risks of wireless networks are becoming the focus of attention.

What are the hidden dangers of wireless internet access?

As we all know, the wireless network nodes can normally radiate to about 300 meters, so any computer installed with wireless network card within 300 meters can access the wireless network nodes and may enter the wireless network. Obviously, this convenient access method can easily bring security threats to the wireless network.

For example, a hacking computer within 300 meters can also have access to your wireless network, thus controlling every move in your computer. Although the wireless network is not as strict as the cable network in terms of confidentiality of information, you certainly do not want illegal attackers to easily know your whereabouts in the network, such as which websites you visited, what privacy messages you sent abroad, and so on, which may be well understood by the illegal visitors.

What is more serious is that the illegal visitor not far away from you will easily steal all kinds of account information on your network once you enter your wireless network. This will cause you more security loss.

Therefore, in the face of all kinds of security risks existing in the wireless network, you must act in time to take measures such as encryption technology or network verification and identification technology to ensure that only your pre specified user or network device can enter your wireless network, while others who want to force access to your wireless network through various wireless network technologies will be rejected.
