Title: All About Public Wi-Fi
Public Wi-Fi networks have become a useful part of modern life, providing convenience for anyone who needs internet access outside of their home. From coffee shops, to airports and hotels, these networks offer connectivity, but can also come with cybersecurity risks. Understanding these risks and taking proper precautions can help protect your personal information from potential threats. In this article we will cover what you need to know about staying safe on public Wi-Fi, including risks and safe practices.

- What is Public Wi-Fi?
Public wifi can be secure or unsecured.
An unsecured network can be connected to without any type of security feature like a password or login.
A secured network requires you to agree to terms and conditions, create an account, or type in a password before connecting.
No matter what connection type, it’s important to use public Wi-Fi with some caution.
- Risks of Public Wi-Fi
Public Wi-Fi networks are often unsecured and more vulnerable to cyberattacks than private connections. Hackers can exploit these networks in several ways:
Man-in-the-Middle (MitM) Attacks: Cybercriminals intercept data transmitted between your device and the Wi-Fi router, allowing them to steal login credentials, credit card numbers, or other sensitive information.
Malicious Hotspots: Hackers may set up fake Wi-Fi networks with names similar to legitimate ones. Unsuspecting users connect to these rogue hotspots, unknowingly exposing their data.
Packet Sniffing: Attackers can use software to monitor and capture data packets transmitted over the network. This allows them to collect unencrypted information such as usernames and passwords.
Malware Distribution: Some public Wi-Fi networks may be compromised to deliver malware to connected devices, potentially allowing hackers to access files or even take control of the device.
- Best Practices for Using Public Wi-Fi Safely
To safeguard your personal information, follow these cybersecurity practices when connecting to public Wi-Fi.
Try to connect to secure public networks whenever possible. In the event that you’re unable to connect to a secured network, use an unsecured network as long as it requires a login or registration.
Use your best judgement, and avoid accessing personal information while on public Wi-Fi, such as banking details or sensitive personal data. This includes making purchases online. If you need to access sensitive accounts, using your mobile data connection is often safer than public Wi-Fi.
Most smartphones, laptops, and tablets have automatic connectivity settings, which allow you to connect from one hotspot to the next. This is a convenient feature, but it can also connect your devices to networks you ordinarily would not use. You can keep these settings turned off for safety reasons.
Also consider using a Virtual Private Network (VPN). A VPN encrypts your internet traffic, making it much harder for hackers to intercept and read your data, which protects your online activity.
Ensure that your device’s operating system, antivirus software, and other applications are up to date. Security patches help protect against vulnerabilities that hackers might exploit.
Multi Factor Authentication (MFA) / Two Factor Authentication (2FA): Consider enabling 2FA on accounts that support it to add an extra layer of protection. Even if someone gains access to your login credentials, they would still need the second factor, eg. a number code, to access your account.
Forget Public Networks After Use: When you disconnect from a public Wi-Fi network, make sure to “forget” the network on your device. This prevents your device from automatically reconnecting to the network in the future.
It is also a good idea to make a habit of regularly checking your bank and credit card accounts for unauthorised transactions. Detecting suspicious activity early can minimise potential damage.
- Conclusion
While public Wi-Fi is convenient, it comes with risks that can jeopardise your personal information and online security. By adopting good cybersecurity habits such as using a VPN, keeping software updated, and being cautious about the type of data you access on public networks, you can enjoy the benefits of connectivity while keeping your data secure.
