Being connected to the Internet has become a necessity these days. At home, our devices are usually connected through a secured wireless router that uses Wi-Fi. I say secured, because the wireless router at our homes are typically configured with a password. Anyone, who wishes to access the network, must input the password to be allowed to connect. Of course, the strength of the password plays a major role.
However, once you venture beyond the confines of your home, you must find another way for your devices to connect to the Internet. If you don’t have mobile data, you may be tempted to access a public Wi-Fi or Hotspot, if you choose to do so, you’ll need to know a few Public Wi-Fi Security Tips.
Public Wi-Fi networks, which can be found in places like your favorite coffee shop, at airports, and hotels, provide a convenient way to access the Internet while on the move. But this convenience from public Wi-Fi comes with risk, as your privacy and security can be affected.
These networks are usually not encrypted and have poor security measures, leaving your data vulnerable to interception by hackers and other cybercriminals. But fear not, you can significantly improve your online privacy and security when using public Wi-Fi.
Always be wary of open Wi-Fi networks or hotspots. Some hotspots provide greater security than others. Avoid connecting to hotspots with generic names or weak security features. Use only networks offered by reliable, reputable organizations, and, if at all possible, verify their security measures before connecting to them. It is always better to join public Wi-Fi networks that require a password rather than those that don’t.
More reputable organizations may offer a captive portal, which is a webpage that is presented to new users to join the network. Captive portals may require authentication, payment, approval of an end-user licensing agreement, acceptable use policy, survey participation, or other legitimate credentials that are adhered to by both the user and hotspot provider.
2. Use a Virtual Private Network (VPN)
When connecting to a public Wi-Fi network or hotspot, consider using a Virtual Private Network or VPN. A VPN adds a layer of security as it encrypts all your Internet traffic, creating a secure tunnel between your device and the Internet, regardless of the network you’re on. By routing your Internet traffic through a secured server, the VPN creates a private tunnel that shields and protects your data from online intruders.
When connecting to a public Wi-Fi network or hotspot, it is advisable to use a Virtual Private Network (VPN). A Virtual Private Network (VPN) enhances security by encrypting all Internet traffic. It establishes a private tunnel between your device and the Internet, regardless of the network you are connected to.
Through the process of routing your Internet traffic via a secure server, a Virtual Private Network (VPN) establishes a confidential pathway that safeguards and defends your data against online intruders. There are many VPNs that can be downloaded for a small fee, such as Express VPN, Nord VPN, and CyberGhost, among others. You can use the Opera browser, that has a built-in VPN that you can use for free.
3. Lay Down Your Firewall
Enable the firewall protection on your device. This serves as a protective barrier, selectively screening incoming and outgoing communications while preventing potential security risks from accessing your device. Firewalls for Android devices include DataGuard, AFWall+, Netguard, and NoRoot, etc. Firewalls for iOS devices include FortiClient, Threatlocker, and Trustwave, etc.
4. Stick to HTTPS Websites
Make sure that the websites you visit on the internet employ HTTPS (Hypertext Transfer Protocol Secure) encryption when you are browsing the online. Check the address bar for the presence of the padlock icon, which indicates that the connection is safe and that the data is encrypted.
5. Enable Two-Factor Authentication (2FA)
Whenever possible, use Two-Factor Authentication, often known as 2FA, on all of your online accounts. Both your password and a second form of verification, such as a code that is given to your phone, are required in order to use two-factor authentication (2FA), which provides an additional layer of protection.
6. Limit What You Do Online
Don’t access sensitive information or conduct financial transactions like accessing your bank account while connected to public Wi-Fi networks or Hotspot. It’s advisable to only access sensitive information like your bank information from a secured location like our home or workplace.
7. Keep Your Software Up-To-Date
Ensure your device’s operating system, antivirus, web browser are all up to date. Most devices have automatic software updates that would include security patches for known system vulnerabilities.
8. Disable Auto-Connect
Many smart devices are pre-set to automatically connect to any Wi-Fi network that is accessible, be it a secured network or not. This feature should be disabled in order to prevent accidentally connecting to unsecure networks.
9. Disable File Sharing
Disable file sharing on your device to prevent unauthorized access to your files and folders.
10. Be Vigil of Your Surroundings
Whenever you’re in a public location, always be aware of your surroundings. There is always the possibility that your phone or tablet may be stolen or used by an unauthorized person. Ensure your devices are always kept near to you, and you should never leave them unattended, especially if they contain sensitive information.
It’s easy to become totally engrossed with our phones or tablets, but you must be aware of who is around you. Watch out for so-called “shoulder surfers” who try to look at your screen or listen in on your conversations to get private information like passwords, credit card numbers, or other personal details. Put yourself where it will be hard for other people to see your screen or hear what you’re saying.
11. Log Out and Lock
And last but not least, when not using your device, or you’re no longer using a website or app, always log out of your accounts and lock your device. In the event that your device is misplaced or stolen, this helps prevent any unauthorized access.
Summary
There are public Wi-Fi networks or hotspots everywhere, and they certainly have the attraction of providing ease of connectivity when you’re on the move. On the other hand, hidden behind this convenience exits a number of cybersecurity dangers that can threaten your privacy and security. By following the simple but proactive steps outlined above, you can minimize the risks of cyber threats and safeguard your personal information.
Utilizing Virtual Private Networks (VPNs), validating network security, maintaining software updates, using strong passwords, and exercising good security practices and behaviors, can go a long way to protecting your most vital information while connected to hotspots. So the next time you want to connect to a public wireless network or hotpots, always remember to be cautious and vigilant. The security of your data will depend on it.
