What steps can I take to secure my Wi-Fi network?
To secure your Wi-Fi network, start by changing the default username and password of your router. Many routers come with a default password that is easily accessible online and can be exploited by cybercriminals. Choose a strong password that includes a mix of letters, numbers, and symbols, and change it periodically to minimize risks.
Next, enable network encryption, preferably WPA3, as it provides the highest level of security currently available. Also, consider hiding your SSID (network name) so that it does not broadcast publicly, making it less visible to unauthorized users. Regularly check the devices connected to your network and remove any that you do not recognize.
Is it safe to use public Wi-Fi networks?
Using public Wi-Fi networks can pose significant security risks, as they are often unsecured and can be easily monitored by malicious actors. Avoid accessing sensitive information, such as online banking or personal accounts, when connected to public Wi-Fi. If you must use it, make sure that you access sites with HTTPS protocol, which provides an added layer of security.
