Wondering how to use public WiFi safely? As we are living in the age of modern technology, the internet is essential whether its for work of study purposes. But what if you are outside and you have to check something important your boss asked you to do, or you need to attend your Zoom meeting? Public WiFi could be a saver, but how sure are you that it is safe to connect? This post will help you know the risks of connecting to public WiFi and how to use it safely.
Understanding the Risks of Public WiFi
Indeed, public WiFi is a lifesaver, especially when you need to connect to the internet immediately. The bad news is that when you connect to free networks in places like cafes, airports, or hotels, you’re often on a shared, unsecured connection, and that opens the door to a number of risks. If you are always connecting to public WiFi, here are some of the risks you should be aware|:
1. Data interception
When you connect to a public WiFi, hackers may see what you’re doing online as many of them have access to a tool that they call “eavesdrop.” That means any personal info you enter, like passwords, credit card numbers, and emails, can be captured without you even realizing it.
2. Man-in-the-middle attacks
This is when the hacker creates a landing site that can get all your data. Here is the scenario: when you open a site and enter your data, instead of directly going to the site you access, the data will go through the attacker, and that will allow them to view or even change the information being sent.
3. Fake WiFi networks
Hackers can also set up fake hotspots with names similar to the legit ones, like “Free Airport Wi-Fi.” Now, you will think that it is really the free WiFi, but little do you know the hacker is monitoring everything you do, infecting your device with malware. If your device doesn’t have any antivirus, connecting to the wrong network can expose you to viruses, spyware, or ransomware.
4. Session Hijacking
Your email, social media, or bank can also be at risk when you connect to a public WiFi. This happens when the hacker steals your session cookies and accesses your logged-in accounts without needing your password.
5. Exposing the IP address
When you connect to public WiFi, your IP address or your device’s digital ID becomes visible on the network. When an IP address is exposed, hackers or snoopers can use it to see your location. On unsecured networks, your IP can also reveal browsing habits, making you an easy target for tracking or phishing attempts.
Steps to Use Public WiFi Safely
Despite all the risks mentioned above, it is no secret that public WiFi is still used by many individuals, even me actually”. Well, it is because of the convenience it can offer. Imagine you don’t need to pay for your internet connection and yet you can use it as long as you want. To enjoy it more, check out the steps on how you can use it safely.
Verify the Network
When using public Wi-Fi, always make sure to verify the network you are connecting to. You can do it by asking the establishment or staff for the correct SSID name, which can help avoid falling into the trap of fake WiFi hotspots set up by cybercriminals. Connecting to a legitimate network reduces the risk of falling victim to malicious activities.
Use a VPN for Enhanced Security
To enhance my security while using public wifi, opt for a Virtual Private Network (VPN). By using a VPN, you can encrypt your internet connection and ensure that your online activities are protected from prying eyes. This extra layer of security is essential for keeping your data safe from potential hackers lurking on public networks.

With the help of a firewall, you can monitor and control incoming and outgoing network traffic. Just keep the firewall turned on so you can have additional protection against unauthorized access to your device.
Disable File Sharing
When connected to public wifi, you should make it a point to disable file sharing on your device. This prevents others on the same network from accessing my files and sensitive information. Disabling file sharing also allows you to have control over who can view and retrieve data from your device. This can minimize the risk of data breaches or unauthorized access.
Choose HTTPs Websites
Make sure to check for HTTPS in the website address because it is more secure than HTTP. When you use https, it can be harder for hackers to intercept any data exchanged between your device and the website.
Update Your Software Regularly
Maintaining up-to-date software on your devices is essential for staying safe while using public WiFi because it often contains patches for known security vulnerabilities. This would help to keep my devices protected against the latest threats. This can also reduce the risk of cyber attacks and ensure that your data remains secure when you are connected to public networks.
Log Out From Services After Use
After completing your online activities on public WiFi, make sure to log out of all the services you use to protect your sensitive information and minimize the chances of someone accessing your accounts without your permission.
