Quick Look your Right Eyes and Ears while using Public Wi-Fi Network by Waqas on January 18, 2014 in Security & Vulnerability Research has revealed that public Wi-Fi networks are more dangerous than one might realize. They can be like ripe fruit for hackers. Setting up a fake Wi-Fi network to steal personal information is an easy task for these hackers. When a user tries to connect with public Wi-Fi, especially at an airport or coffee shop, he/she may not know whether the Wi-Fi network signal is authentic or fake. It is here that hackers could steal your data over such public connections. Such unsafe surfing is sure to open you up to a number of online threats. We’ll talk about some of these security risks involved in accessing public Wi-Fi. ![]() What threats could be expected while using a public Wi-Fi? Well, an unsafe surfing is likely to attract a number of online threats let us see some of them: Evil Twin/Wi-Fi Phishing: Justifying its name, in Evil twin the access routes creates a cloned network with a same network name. Evil Twin works in the same way as the normal phishing threat does, when the user enters into the wrong access route, evil twin starts stealing system’s data or attacks in any other way. New war drivers: War drivers are those who try to hack network illegally especially on open network like a public free Wi-Fi network. These war drivers could be anyone like hackers, professional criminals or even the employees or competitors of the particular business. Viruses: One of the ancient types of the online threats is virus also influence wireless network. Viruses enter into the wireless network, send requests, and connect to the local area networks to make a way to the nearest wireless networks and corrupt the network system coming in its way. Data eavesdropping: This is very common Internet threat. With lots of interceptable signals and data sharing techniques, eavesdropping also prevails in public Wi-Fi network. How can you keep a safe distance from threats? All you have to do is to stay alert and updated. Following steps will help you to stay protected while using a public Wi-Fi network: 1. Turn off Sharing Many times, we use computers and Internet for sharing purposes such as files, images, audios, videos, graphics, and printers and so on. Being on a public network it is obvious that someone will try to access your data and files. To prevent this you need to turn off the sharing feature of your OS. Windows: For turning off sharing files on windows: Go to the Control Panel from the Start menu and click on the Network and Sharing Center. On the left corner, click on the Change advanced sharing settings and under the Home or Work tab Change the settings as given below: Network Discovery: off File and Printer Sharing: Off Public Folder Sharing: Off File Sharing Connections: Use 128-bit encryption. Click on the Save Changes button. Mac OS X: Go to Apple menu and then click on the System Preferences. From the System Preferences window click on the Sharing in the third row Now a new window will open. In that window, see the checkbox in the front of the File Sharing. If it is checked then uncheck it. Close the window. 2. Turn on the Firewall Although the firewall does not secure the network thoroughly, it is still necessary to keep unwanted traffic away from the network. Operating Systems like Windows and Mac OS X come along with the basic Firewall. Windows: To turn Firewall on in the windows, just go to the Start > Control Panel > System Security > Windows Firewall. Mac OS X: In Mac OS X, go to the System Preferences > Security and Firewall and turn it on. 3. Update your antivirus software Installing the antivirus software is not enough; you also need to update it from to time-to-time. Antivirus software will alert you on finding any suspicious content. 4. If not in use then turn it off If there is no need of internet connection then turn the Wi-Fi connection off. Keeping Wi-Fi during idle time may invite unwanted vulnerabilities, and can result into snooping or sniffing attack. 5. Implement VPN Virtual Private Network is widely famous for keeping your entire stuffs private. VPN are available in both paid and free modes. This is the perfect alternative and an unbeatable solution for those who frequently need to connect with public Wi-Fi networks. 6. Check for SSL An SSL secured website is always starts with HTTPS. SSL confirms the encryption process carried out by that website/server, and hence guarantees a secure online communication. Any site, which is not https, is not worth trusting. Certificate authority issues SSL certificate that is used to secure domains, websites, web applications, software, source code, documents, as well as mobile applications. So always, make sure that you check for the “https” in the websites before dealing out with any website. 7. Two-step authentication-a safer method to avoid threats All the reputed businesses or websites have implemented two- step authentication process, which is also called two-factor authentication. In this process, one has to provide two different credentials to log on to one’s account. Therefore, even if any hacker reaches up to your password, he/she will not be able to access your account without authentication code. 8. Being available all the time is not good for your health Staying online all the time is also one of the reasons of hijacking of your email accounts or bank accounts or account of social networking sites. After finishing your work, you should log out from all of your accounts. In addition, one should disable the setting in laptop and mobile phone of automatically connect to the Wi-Fi hotspots. Below is the process of disabling Auto- connecting to public Wi-Fi networks in windows.
Working on Internet is not as safe as it should be, one should be aware of the prevailing threats and their prevention. Click here to view the whole thread at www.sammyboy.com. |
