Eagle for security measures against Wi-Fi and prevent unauthorized use!
Keep in mind that convenient Wi-Fi is also next to risk
The convenience of Wi-Fi is that it can be used anywhere within the range of radio waves.However, if you turn it over, it is also next to the risks such as the content of the communication.The communication between the Wi-Fi router and the child unit is encrypted and protected, but the danger setting of the router is poor or using the default password increases the danger.[Visual explanation] Means to prevent eavesdropping and illegal use on the Internet
■ Check on the router setting screen
If you check the connection destination on the iPhone, it may be displayed as "low security".This is a warning that points out the weakness of the router encryption method.Although there are several methods, it is essential to use the encryption algorithm "AES" used for Wi-Fi data communication or file compression.Let's check on the router setting screen.
■ Review existing IDs and passwords
Wi-Fi 6 supports highly safe WPA3, but cannot use automatic setting functions such as WPS.The initial setting of the router is basically WPA2, and it is necessary to manually set it in WPA3.WPA2 and WPA3 are security protocols for Wi-Fi.The vulnerability was discovered in WPA2, and it was strengthened with WPA3.In principle, the encryption method must be set up with a router and a slave unit.Some devices are not compatible with WPA3, and some products have WPA2 and WPA3 SSIDs.In order to prevent router takeover, I want to change the password required to open the setting screen.It is also important to keep the firmware up to date to avoid router vulnerability.(Writer Shunsuke Igarashi) [Nikkei PC21 January 2022 Issued Articles published]
