The most commonly used public Wi-Fi are those offered by the airports, restaurants followed by the hospitality departments. However, the public wireless network is usually used by youngsters as this group has smaller data plans. It makes them vulnerable to the attacks.

Type of Data used by the device under threat

Frankly, when an individual is using a public Wi-Fi network, they are willingly or unwillingly risking all types of existing and historical data information of their devices. There are several personal credentials, financial information, and location data stored in everyone’s mobile phone.

In addition to this, they do save their passwords of the social media sites, photos in the gallery and personal credentials, email accounts and banking accounts as well. These could easily be accessed by the malicious hacker which can wreck the lives of the users.

Challenges of public Wi-Fi

An opinion poll took place last year reported that much more people are aware of the use of Public Wi-Fi than the public toilets. On the contrary, a study by privatewifi.com found that almost 75% of the American users of internet said that they logged in to their personal email accounts using public Wi-Fi.

Therefore, when someone uses a Public Wi-Fi their data can be use illicitly by the following:

• Wi-Fi manufacturer:

The Wi-Fi creator or Android app developers can easily access and use or sell the users location and whereabouts. These service manufacturers are usually known for transferring confidential information as unencrypted. So, anyone could intercept the data when it is traveling from the user to the data location of the service provider causing a big security risk.

• Authorities:

When someone uses public Wi-Fi, their data can come under the purview of the regional and central system. The authorities can obtain the information on the user’s habits of browsing and associated other details. People could as well be under scanner in the name of national safety. In case, they will have no privacy while using public Wi-Fi.

Protection from the Public Wi-Fi

There is a feature on many mobiles and windows computer that can recall any Wi-Fi network which has been connected in the past. They can even easily reconnect to them whenever they are in range without informing. However, in many systems, this competency is not enable by default.

There could also be an option such as "Forget this Network" on the devices. It can be used to remove the Wi-Fi hotspots which you don’t want to connect automatically.

Using VPN network

Utilizing a virtual private network service will help to safeguard personal identity and data while using public Wi-Fi in various ways. Firstly, a VPN covers all the information coming from the system in the form of an envelope containing headers and metadata that covers an individual identity and the nature of data packets that is transmit over the network.

Secondly, the VPN also encrypts all the data passing through it, utilizing military strength algorithms. Hacking this encrypted code would ask for considerable time, energy and sources on the part of any hackers or other agencies who may try to hack through it.

Thirdly, the VPN services also function from an array of geographically scattered website servers. It is the IP addresses of these VPN servers that are linked to the connection.

Restricting online activities

Public Wi-Fi channels make it easier for cyber hackers to follow and extract confidential information, financial information and online documents. Therefore, it makes a sense for people to present them with limited opportunities to do so as much possible.

Not all snooping may be technical; someone just needs to aware of their surroundings too when they sit down to surf on Public Wi-Fi.
