How to judge whether the hotel wifi is safe?

The following methods are needed to judge the security problem of hotel wifi:

1. Check the security authentication protocol of hotel wifi: Check whether the hotel wifi supports the use of WPA2/WPA3 security authentication protocol. WPA2/WPA3 is the most secure encryption protocol at present, which can effectively prevent others from stealing network information.

2. Check whether the hotel wifi requires a password: If the hotel wifi can be connected by inputting information such as room number or hotel name, and no password is required, it means that the hotel wifi is low in security and easy to be stolen by others.

3. Check whether the hotel wifi supports the HTTPS protocol: HTTPS protocol can ensure that data is not stolen during transmission. If the hotel wifi does not support the HTTPS protocol, it means that the user's private data may be stolen when using this wifi, and the security is low.

4. Check the security settings of the hotel wifi: If the security settings of the hotel wifi are not strict, for example, all ports will be opened without opening the firewall, then there may be security loopholes, thus making the user's network information easy to be stolen by others.

To sum up, to judge the security of hotel wifi, we need to carefully check the security authentication protocol, whether we need a password, whether we support the HTTPS protocol, and the security settings of hotel wifi to ensure network security.
