Public WiFi : A Boon or a Bane

                    From a common man to corporate society, everyone is depending on Wi-Fi networks. As they can provide internet over a wide area uninterruptedly sometimes even faster. Nowadays in every commercial center such as hotels, coffee shops, malls, airports, railway stations, etc open Wi-Fi is provided. 


            The open Wi-Fi which we think useful to us is also being useful for the hackers to sneak into our personal data and read it without our knowledge. We people will not think twice once a thing is given for free. While the commercial center does this for the attraction of more customers these hackers take it as an advantage and take on our resources. So now you think of not using open Wi-Fi. Keep that thought away and know the secure ways to access open Wi-Fi.

 

Wireless Fidelity

What makes it dangerous?

 The problem is that hackers can use Wi-Fi as a connection between them and the user. They can easily read the data that is sent through the Wi-Fi with ease. The data will not directly go through the Wi-Fi but through the hacker who can track your personal details like important mail, banking details, password credentials, and many more. They connect to the same Wi-Fi as you are connected and can take every detail out of your device with weak security. There are many purposes for this act.

 

Man in the Middle Attack

This attack of hackers on your device is commonly called as “Man in the Middle” which is pretty much eavesdropping. When data is sent through various points these hackers take control of it and can read anything you share. The transferred data you considered secure is not secure.

 

Malware :

        The hackers can implant the virus in the file you shared and can plant it in your device. So that the device you think secure can be assessed by them. Sometimes they send the virus in the form of pop-ups that contain updates or news and once you click on it, the system is theirs. They alter the code in the system making a malfunction of the device.

 

Unencrypted networks

        Encryption is the modern word that makes us feel secure. Because of the complexity of decryption and the difficulty to find data, encryption is preferred. But when you send your data through a network that is unencrypted, the same data you transferred can be seen by the hacker. If you are a business person and you are using login credentials using this Wi-Fi then maybe your whole company is at stake. 


        Usually Wi-Fi routers are shipped with encryption turned off. It is the responsibility of the network provider to turn it on. If it is in hands of an educated individual then he can turn the encryption on. But in case it is turned off think of the consequences.

 

Unauthorized sources

  The hackers are now using certain software tools and devices to help them to hijack your device. By this, they can track your online activity. Other than this they make use of fake routers with the name of the standard Wi-Fi routers and when a user connects through it, they do their job and make your data unsafe.

Virtual private network

How to secure your connection

1.  Use a Virtual Portal Network (VPN). Because it makes your data more encrypted and the hacker rather than spending his time on decryption and further process, selects an easy target.

2.  Always enable the ‘HTTPS’ option in the website that you often use or in the website that you use your private information. Even if you have an app for that website, make use of the website and enable the option so that it can add an extra level of encryption.

3. When you are connected to Wi-Fi ensure that your sharing option is disabled or let your device to disable on its own.

4. Only turn ON Wi-Fi in the time of necessity. Don’t let the device connect automatically to Open Wi-Fi. Even if you are not connected there is a possibility of sharing information.

5.   Use Internet security anti-virus so that they can act as a firewall for your device and encrypt the data from the hands of hackers.

6.   Don’t use the website that handles your personal information so that you can maintain your privacy safe.

7. Don’t perform transactions on a Wi-Fi network which may lead to disclosing your banking information.

8.   A simple step is to buy a larger data pack so that you need not depend on other hotspots/free Wi-Fi.
