VPN for Public WiFi Security – Will It Safeguard You?
VPNs for public WiFi security: Coffee shops, airports, and supermarkets have public WiFi hotspots. Many individuals are unaware that using public WiFi networks to connect to the internet might drastically damage your online security.
You've heard of VPNs (Virtual Private Networks) and their myriad security perks, but how effective is a VPN for public WiFi security? Continue reading to find out more.
To Begin, What Exactly is Public WiFi?
We've all heard about WiFi and the advantages it provides. WiFi is a wireless communication technology that connects computers and other devices to the internet. WiFi is used with a wireless adapter to create a “hotspot.” Users within a hotspot's radius can connect to the internet network after a connection is established.
Wireless networks can be found in the house as “closed networks” or in public locations as either open or closed networks, depending on the security settings. When using public WiFi, users' security is regularly jeopardised.
Where Can I Find Public WiFi Networks? VPN for Public WiFi Security: Where Can I Find Public WiFi Networks?
There are various public WiFi networks to choose from. Public Wi-Fi networks are widely available in many parts of the world, and you may come across them in your regular life or while travelling.
Worldwide, there are over 100,000 unprotected public WiFi hotspots, with reports indicating that one in every four is entirely unsecured.
WIFIEU is a European initiative that aims to provide free WiFi in public areas throughout the European Union. Mumbai is the largest public WiFi city, with over 500 operational hotspots and another 700 planned by May 2017. Another major metropolitan centre with a considerable presence of public WiFi is New York City, where all subway stations will have WiFi connectivity by the end of this year.
These networks are common in the following areas:
• Airports, planes (including those with WiFi in flight), trains, subways, and transportation hubs
• Bars, restaurants, cafés, and coffee shops
• Inns and hotels
• Internet access in public parks and other public places
• Shopping centres and retail establishments
• Tourist attractions and commercial centres
• Unsecured household networks
The Risks Associated with Public Wireless Networks
When you utilise a public WiFi network, you never know who else is observing your internet connection. For a variety of reasons, public WiFi can be problematic:
Data flow on public WiFi connections is often not secured, putting network security at risk.
1. Hackers can simply track your travels and steal important information.
2. Some people set up false hotspots that look real and then exploit them to steal important information from you.
Hackers eavesdrop on public WiFi users using several tactics, emphasising the significance of using a VPN for public WiFi security:
1. Unsafe connections
While connected to public WiFi, an internet user communicates with the server over an unencrypted connection. As a result, data is unsafe, making it an easy target for interception. Furthermore, if you've ever wondered if the owners of public WiFi may view your search history, the answer is yes, thanks to monitoring software.
2. Attacks with a man-in-the-middle
Because public WiFi connections are unencrypted and unsecured, you are vulnerable to a man-in-the-middle attack. It occurs when thieves intercept data by inserting themselves into a discussion between a user and an application or website. This allows them to find information shared between two people, such as account access and purchase transactions, which could lead to identity theft.
3. Malware propagation
Hackers can use software faults to install malware on your device by building code that exploits a specific flaw. When you connect to an unsecured public WiFi hotspot, malware such as viruses, worms, trojans, ransomware, adware, bots, and spyware can penetrate your system.
4. Session eavesdropping
Hackers attempt to hijack a user's session to gain their session ID, which they then use to impersonate the user on network services. This could happen while you're buying online, for example.
5. Sniffing and spying offences
Sniffing and snooping are internet fraud techniques used by attackers to collect valuable data across an unprotected network. They have the ability to intercept WiFi signals and track your internet activities.
After all, people connecting to public networks make it much easier for hackers to accomplish their business. According to recent research, almost a third of public WiFi users access password-protected personal accounts, 22% use credit cards, and 31% use online banking – all of which are targets for data thieves.
Worryingly, despite the risks, people are prepared to use these networks. According to McAfee research, 38% of consumers still prefer using free unprotected WiFi.
When combined with data from the AARP's Convenience vs Security report, which claims that “a quarter of Americans who use the internet access it via public WiFi once a week or more,” the use of unprotected networks becomes clear.
So, yeah, things aren't looking good. However, for public WiFi security, we have a VPN.
VPN Service for Public WiFi Security: How to Protect Yourself When Using Public WiFi
While there are various methods for staying safe when utilising a WiFi network, one technique stands out above the rest: using a VPN for public WiFi security. The most crucial thing you can do is to always connect using VPN.
But how can a VPN protect you from the perils of public WiFi? Let us investigate.
1. Data encryption – VPN’s main advantage and the primary reason to use VPN for public WiFi security.
All of your internet transactions are encrypted when you use a VPN. No one can intercept it using public WiFi since the data is scrambled and unintelligible. There are numerous methods of VPN encryption. However, AES-256 encryption is the gold standard in the security sector (the last three digits represent the length of the secret key).
2. Secure connection –
A VPN secures your connection by routing it through encrypted tunnels to VPN servers, where you are assigned a new IP address. VPN protocols are involved here, which are collections of programmes and processes that determine how the tunnel is constructed.
VPN protocols are classified into six types:
*OpenVPN is one of the most widely used VPN protocols. It employs either the TCP or UDP Internet protocols; the former ensures that your data is sent in its full and in the correct order, whereas the latter prioritises faster speeds.
*IPSec/IKEv2 – This VPN protocol delivers a secure, stable, and fast connection, although it is less compatible than OpenVPN.
*WireGuard – The most recent and fastest tunnelling protocol outperforms both prior options.
*SSTP – Microsoft's VPN protocol that is relatively safe.
Point-to-Point Tunneling Protocol is abbreviated as PPTP. The first commercially used VPN protocol was PPTP, which was established in 1999. It does, however, currently provide some of the most unsafe encryption.
L2TP/IPSec is an acronym for Layer 2 Tunneling Protocol. It is merely a VPN tunnelling technology that connects your device to a VPN server but does not provide encryption.
3. IP address concealment
– A VPN effectively establishes a new online persona by disguising your actual IP address (which can give away a lot of personal information, like your location).
4. Anonymity – You receive an anonymous IP address to protect your genuine identity and keep your online privacy.
Despite the risks of public WiFi and the fact that using a VPN for public WiFi security is the easiest method to avoid them, few people use it because they believe that open free networks will not hurt them.
They couldn't be more wrong, unfortunately. So, if you haven't previously utilised a VPN while accessing public WiFi, it's never too late – now is the time to join the ranks of those who have.
Other Ways to Stay Safe While Using Public WiFi
Aside from utilising a VPN to safeguard public WiFi, you may take various steps. The first step is to be alert – remember to “think before you connect.”
Recognising that connecting to a WiFi network in a public setting, particularly one labelled “free,” puts your security at risk is vital. It is also critical to understand what you agree to.
When you accept the terms and conditions of a public WiFi hotspot, you're granting the operator permission to gather information about you or what you're looking at.
Once informed, you can make better judgments about when to connect (or not!) and actively preserve your privacy.
Other solutions for protecting your privacy include:
Disable file sharing – You can disable file sharing on your device. By picking this option and eliminating AirDrop on iOS and printer sharing, you may prevent hackers from stealing your important and personal information.
Disable WiFi auto-connect – On occasion, hackers will utilise fake networks with the same name as a legal network. If you disable auto-connect on your smartphone, you will not be linked to fake networks.
Avoid using login details – If you aren't utilising a VPN for public WiFi security, avoid logging onto your internet accounts and entering passwords. Passwords for internet banking, email, social networks, and other services are all entered.
Is Using a Free VPN for Public WiFi Security a Good Idea?
Privacy is a vital asset in an age of extensive digital tracking. Many smartphone users save money by using free VPNs, which is a massive error.
A free VPN service is not the most excellent method to handle your privacy issues. Over 20 million free VPN users' individually identifying information was published online in 2020. Some free VPN services will sell your information if unintended data exposure isn't terrible enough.
Free VPNs are problematic since they undermine your privacy rather than protect it. Some free VPN service providers, in particular, lack the resources necessary to safeguard your data and prevent others from selling it unethically. As a result, you should exercise caution when installing a free VPN client.
Here are five reasons why utilising a free VPN to secure public WiFi is risky.
1. Free VPNs capture and sell personally identifiable information about you.
When preserving your privacy, most free VPN programmes aren't exactly saints. Not only do they gather, but they also sell your personal information.
This brazen disdain for user privacy derives from a simple fact: free VPN companies must fund the costs of hosting servers, paying personnel, and financing other operational expenses. To stay in business, free VPNs must sell your data.
2. Vulnerabilities and malware are present in free VPNs.
You are most certainly using a VPN to browse privately. However, how secure are free VPN services? Certainly not. Security experts have uncovered significant issues in ten of the most popular free VPN apps on Google Play.
Free VPN programmes are nothing more than a cover for a malware dissemination strategy. As a result, instead of keeping your online behaviour secret and secure, they do the reverse.
3. Free VPNs slow down your internet connection.
If free VPNs are good at one thing, it's showing you a spinning wheel. Why? Because they drastically slow down your internet connection. It means you'll have to spend time hunting for free VPNs that function, followed by even more time gazing at half-loaded internet pages.
4. Free VPNs cause
CAPTCHA requests are made.
You know, the little images of buses, boats, and crosswalks used to distinguish between real people and algorithms. Proxy traffic via free VPN providers commonly triggers CAPTCHA requests. As a result, if you wish to utilise a free VPN, expect algorithms to challenge your humanity daily.
5. Free VPNs display invasive ads
Advertisements are the cost of browsing secretly and anonymously. Some VPN companies that do not charge a fee for their services will occasionally show pop-ups or link you to pages with sponsored content. For starters, ad-filled VPNs are inconvenient and can cause your browser to slow down.
