How to ensure the safety of wireless network

With the increasing number of businesses and individuals using wireless networks and wireless access, security issues are becoming increasingly prominent. More than 50% admitted to having used someone's wireless internet access without explicit permission. This has led us to ponder the question of how to stop someone, especially the "next door", from stealing or stealing their own wireless connections. Here I provide you with eight tips to protect your wireless network security:

　　Using encryption technology

Today's production of wireless routers almost all provide users with the choice of encrypted data, the proper use of this feature can avoid their own bank account details (including passwords, etc.) will not be intercepted by malicious people. However, it is important to note that the Wi-Fi Protected Access technology (WPA and WPA2) is more robust than the WEP protocol and therefore has a greater role in securing wireless communications.

　Using MAC address filtering

Under normal circumstances, wireless routers and access points have the ability to prevent unknown wireless devices from connecting to the network. This function is achieved by comparing the MAC address of the device that is trying to connect to the router and the MAC address of the device saved by the router. Unfortunately, this feature is usually turned off when the router is out of the factory, because it requires some effort from the user to make it work correctly, otherwise it will not be able to connect to the network. Therefore, by enabling this feature and simply telling the router the MAC address of the wireless device in the unit or home, we can prevent others from embezzling their Internet connection to enhance security.

But do not rely entirely on this measure, or you can say that using MAC address filtering is not a panacea for hackers who are hell-bent on cloning MAC addresses and trying to connect to a user's wireless network, but you should use this measure to reduce network risk.

Be sure to use a password

Setting a password for wireless Internet access is critical. Choosing a strong password helps to secure your wireless network, but do not use the default password that accompanies the wireless router, or use a word that can be easily detected in a dictionary or a family's birthday.

　Turn off the network when you are not using it

If a user's wireless network does not require 24 hours of service per week, it can be turned off to reduce the chances of being exploited by hackers. While many companies are not able to leave the network, it may not be realistic to put this recommendation into practice. But one of the most significant improvements to a system's security is to close it directly. Because no one can access a service that does not exist or open.
