Inside public WiFi Hot spot security closet how to security on the Internet is high!

CCTV's "315 Nights" site, demonstrates the hackers how to use false WiFi Hot spot steal the show the audience the mobile phone system, brand models, since a photo, the mailbox account password, and other kinds of privacy data, and this is also for all mobile phone users on a public WiFi internet security inevitably nervous. Fear and accusations, we should think about the reasons why there is such phenomenon, as well as their own how to avoid it would be better?

Public WiFi hotspot security risk what are the main?

Accompanied by moving the development of the Internet, the mobile phone to the online payment, mobile phone shop, mobile phone business, mobile phone on the Internet banking, e-commerce applications in the mobile end-rapid development, and also WiFi the road. According to the data, about 10 per cent of the population is using WiFi Hot spot, as one of the largest markets in the world, China's current public WiFi hot coverage at least more than 10 million, and this service has almost become a public services in the context of the standard configuration. However public WiFi, free WiFi factor has also been a major challenge.

Generally speaking, the public WiFi, we may be faced with two type of attack.

The Web listener attack

  Simply put, that is in a common network, an attacker can easily eavesdrop on your network, for example, upload to circle of friends.

There are two ways that a ARP attacks, it in your phone/computer and the router between the pseudo-caused transit station, it can not only see all of the traffic, but also the traffic speed limit.

  In addition a network card in promiscuous mode, it can be received by all broadcast traffic. This conditional, that is, the network is the broadcast of the device, such as HUB. Everyone in your company or Internet cafes can often be seen HUB, a "Network Cable to several 10 network cable out of the expansion device. If this public WiFi there are such facilities, is usually your Internet traffic may be wiretapped.

  To address the above two ways of protective practices are also very mature, ARP firewalls, traffic to be encrypted (I have used a Software Safety WiFi is the traffic is encrypted)

Forged WiFi attacks - "WIFI fishing hot spots

  If you are connected to a public WiFi, it is very likely to be vulnerable to the attack. This is the case you may find it easy to learn, but there is also another situation that you connected the public WiFi Hot spot. After they might also be attacked.

  The WIFI fishing hot spots is actually a data transfer of the upstream set a valve, all of the customer's data is through the valve with the appropriate Web site for transmission, and the hacker through a specific attack, it can be applied to these data records and grab the analysis.

  Sounds like a magic isn't it? How it works is very simple. To give an example, on the subway, while self-3 G routing to do a "CMCC" password WiFi, your phone will automatically connect to the hotspot WiFi, inside configuration all traffic through monitoring software. There is a very small hole, your phone/computer will automatically connect that have been previously connected all WiFi, just CMCC is no password, forged the convenience.

  It is really wanted terrorist, does it mean that there is no solution?

You want to be safe and efficient use of public WiFi, the following points should be noted:

1. As far as possible, do not use suspicious or not encrypted WiFi network

If you would like to continue to public places on the Internet, which is the most secure way is to use mobile data traffic, although it is expensive, but it is relatively safe. If you need to be connected to a public WiFi, you can use security software to filter, recommend a APP WiFi safely, ensure that you connect the hot point security, and do not connect suspicious or not encrypted Wifi.

 2. Using a Virtual Private Network (VPN)

If you want to use the public WiFi, there is only one way to protect your security - Use a Virtual Private Network (VPN). VPN mean is designed to allow users on a public network, a private network for encrypted communication, it will be your Internet traffic to be encrypted and then connect to your VPN Host and then by VPN hosts on the Internet. As a result, even if the Internet traffic in public places have been intercepted, hackers crack it is also extremely difficult.

3. Try to use HTTPS protocol log in to the web site

HTTPS protocol through the establishment of an information security channels for data transmission. Recommendations in the public WiFi environment as far as possible, do not log into such as Internet banking, Alipay, important accounts.

4. Turn off WiFi default connection

Good WIFI usage habits. The opportunity to use the WIFI hot spots have been recorded, If WiFi switch is in the ON state, and the phone will continue to be around, and search for the event of a same as the name of the hotspot will be automatically connected to a phishing risk. Therefore, when we enter the public area, as far as possible do not open WIFI switch, or the WiFi adjusted to lock the screen, do not automatically connect to avoid in their own do not know the circumstances connected to the malicious WiFi Hot spot.
