What are the possible security risks of accessing the Internet through public Wi hotspots?

1.Public Wi-Fi, if you can connect to a hotspot without a password (for example, you will see that the Wi-Fi signal is not locked) (here it does not mean that you can access the Internet), then this air interface is not secure and is easy to be eavesdropped on by aerial packet capture.

2.If it is WPA, WPA2 Private, Enterprise (EAP) authenticated, then this air link is secure. Mobile currently deploys a PEAP hotspot (CMCC-Auto), which is recommended to be used first, and may be a little troublesome to configure.

Docomo is very smart, first WPA2 private authentication (password public), and then jump out of the portal for real online authentication.

3.Someone else can casually build a fake hotspot, so what should I do? In this case, if the hotspot supports enterprise-level EAP authentication, the man-in-the-middle attack is ineffective.

4.EAP configuration is troublesome, so just wait for Hotspot. Both mobile terminals and hotspots are required.

At present, the WBA is working with operators and equipment manufacturers around the world to do testing, and it may soon appear in China (South Korea has been commercialized last year, and Japan has also started commercial use this year).

5.However, most of the above are security between the terminal and the hotspot, and when it is finally converted to wired, the data is transparent, so it is best to use a VPN at this time. <>

The workarounds are as follows:

1. Open the browser that comes with the phone, and the network authentication interface will automatically appear.

2. Or if the mobile phone browser can't be opened, just open the mobile phone QQ, and then you can find that there will be a "network needs authentication" prompt at the top of the session interface, click to enter the authentication.

3. In the same way, open the browser of the mobile phone, and at this time open the browser that can usually jump out of the authentication interface to open the cognitive interface. Open the browser's history to find the authentication interface that can be opened normally in the past, and click to enter the authentication after finding it.

In view of the above security risks, keep in mind five tips that can greatly reduce the risk of public WiFi hotspot networking.

1. Do not connect to unknown sources of WiFi in public places, and try to choose officially certified WiFi signals. The survey shows that the vast majority of dangerous WiFi is provided by a third party or an individual with ulterior motives, and the official WiFi equipment has a high level of protection, which is generally difficult to break and has a low risk factor.

2. It is best to turn off the "WiFi automatic connection" function when using the mobile phone in daily life. Because if this function is turned on, the mobile phone will automatically scan and connect to the wifi network without a password when entering an area with a wifi network, which will greatly increase the chance of users mistakenly connecting to the wifi phishing.

Hello, dear butler users.

As long as there is a computer that can access the Internet, it is directly plugged into the computer, plug and play, it can form a wireless hotspot with a very stable network speed, mobile phones, tablets and notebooks can be connected to the Internet Then I heard that using this product to surf the Internet, you can also enjoy a lot of benefits, tools.

Mobile phones generally come with a security detection .........Public wifi is generally secure

Use good security software, wifi experience, anti-attack.

We often hear warnings from security experts that public Wi-Fi is not secure and that you should connect with caution.

These warnings are indeed correct, and there is a very large percentage of public Wi-Fi spots that have security risks. A sample security survey showed that 21% of the country's 80,000 public Wi-Fi were at risk.

However, safety experts rarely explain the nature of the hazards, and everyone can only know the reasons for them. We know that when connected to public Wi-Fi, we can steal all kinds of things, but we don't know why we get stolen.

Therefore, it is safe not to carry out operations involving privacy, secrets, online banking, etc. on unfamiliar WiFi.

Hello, dear butler users.

It can prevent others from rubbing the Internet and intercept Trojan fraud, so such a network guarantee is definitely safer.

In addition, the mobile phone scans and logs in without passwords, breaking through the traditional manual entry of passwords.

It can also be installed driver-free to create a strong signal and meet the needs of multiple devices at the same time.

Hello, dear butler users.

At present, the risk factor of WiFi security is gradually increasing, and the connection between public WiFi and free WiFi is easy to be unstable.

Yes, it can not only help you judge the security of wifi to achieve one-click connection and secure Internet access, but also provide a large number of certified security.

Interface. You can check the current WiFi strength value and whether it is safe.

Click the [One-click Identification Free WiFi] button to check the result, and then you can connect.

It provides intelligent mobile phone management functions such as physical examination acceleration, health optimization, security protection, and software management

Hello, dear butler users.

It is a wifi hotspot that can be set up on the computer, transmitting to mobile phones, tablets portable wifi, it is said that the 11th can be reserved, it is a smart hardware product, you can automatically install the driver and complete the wifi creation, and the signal is still very strong, the range is also wide, about a radius of 30 meters.

Then the mobile phone scans *** to connect to wifi without password, and directly manage wifi connection to the anti-rubbing network.
