In an increasingly connected world, smartphones are essential tools for communication and information access. However, when it comes to connecting to public networks, many New Zealanders may unknowingly expose themselves to significant security risks. Public network protection is crucial, as cybercriminals often lurk in these open networks, ready to exploit unguarded devices. Ensuring that your smartphone is equipped with the right security settings can make all the difference in keeping your personal information safe.
This article will guide you through essential security settings to enable on your smartphone before you connect to public networks. By taking proactive measures and understanding the potential threats, you can enjoy the convenience of public Wi-Fi without compromising your privacy.

Understanding the Risks of Public Networks
In today’s digital age, the convenience of smartphones allows us to stay connected even while on the go. However, connecting to public networks—such as those found in cafes, airports, and libraries—can expose your device to a range of security risks. Public networks are often less secure than private ones, making them attractive targets for cybercriminals. They can intercept your data, access sensitive information, and even infect your device with malware.
For instance, a hacker sitting nearby can easily set up a rogue hotspot that mimics a legitimate network, tricking users into connecting. Once connected, they can monitor your online activity or steal personal information. Given that New Zealanders frequently use public Wi-Fi while travelling or socialising, it’s crucial to understand and mitigate these risks.

Enabling Two-Factor Authentication
One of the most effective ways to enhance your smartphone’s security is by enabling two-factor authentication (2FA) on your accounts. This feature adds an extra layer of protection by requiring not only your password but also a second form of verification, such as a code sent to your phone or an authentication app.
When connecting to public networks, your password alone may not be enough to keep your accounts secure. Should someone manage to obtain your password, 2FA ensures that they cannot access your accounts without the second factor. Most major services, including email and social media platforms, offer 2FA options. It’s a straightforward yet powerful step for protecting your personal information while using public networks.
Utilising a Virtual Private Network (VPN)
A Virtual Private Network (VPN) is an essential tool for anyone frequently using public Wi-Fi. By encrypting your internet connection, a VPN prevents outsiders from intercepting your data. This is particularly important when you’re accessing sensitive information, such as banking details or personal messages.
In New Zealand, several reputable VPN services are available, offering varying levels of protection and features. When selecting a VPN, look for one that has a no-logs policy, meaning it won’t store your browsing history. This provides an additional layer of privacy. While using public networks, connecting to a VPN can significantly enhance your public network protection.
Keeping Your Operating System and Apps Updated
Regular updates to your smartphone’s operating system and apps are crucial for maintaining security. These updates often include patches for vulnerabilities that hackers could exploit. When connecting to public networks, an outdated system or application can expose you to unnecessary risks.
In New Zealand, it’s advisable to enable automatic updates on your smartphone to ensure you’re always using the latest version. This practice helps mitigate potential threats from malware or hacking attempts that often target outdated software. Regularly check for updates manually if you don’t have automatic updates enabled, especially before connecting to public Wi-Fi.
Disabling File Sharing and Bluetooth
When using public networks, it’s wise to disable features such as file sharing and Bluetooth unless absolutely necessary. These features can inadvertently expose your device to unwanted connections and data sharing, making it easier for cybercriminals to access your files or information.
For instance, if your Bluetooth is enabled, nearby devices can attempt to connect to yours. Similarly, file sharing options can allow others on the same network to access your files. Always turn off these features when in public spaces, and only activate them when needed to ensure your device remains secure.
Configuring Your Wi-Fi Settings
Your smartphone’s Wi-Fi settings play a critical role in maintaining security while using public networks. Make sure to set your device to ‘forget’ public networks after use. This prevents automatic connections in the future, reducing the risk of inadvertently connecting to a rogue network.
Additionally, consider disabling the option that allows your device to connect to open networks automatically. This will give you greater control over which networks you connect to and help safeguard against potential threats.

Understanding Phishing and Social Engineering
Phishing and social engineering attacks are prevalent risks when using public networks. Cybercriminals often use deceptive tactics to trick users into revealing personal information, such as passwords or credit card details. They may send emails or messages that appear legitimate, prompting you to click on malicious links.
To guard against these attacks, always verify the source of any communication before responding or clicking on links—particularly when connected to public Wi-Fi. Look for signs of phishing, such as poor grammar, unusual requests, or unfamiliar email addresses. Educating yourself about these tactics can dramatically enhance your security while enjoying the conveniences of public networks.
FAQs
1. Why is it important to adjust security settings before connecting to public networks?
Public networks, such as those found in cafes, libraries, or airports, can expose your smartphone to various security risks. By adjusting your security settings, you enhance public network protection, reducing the likelihood of data breaches, malware infections, and unauthorized access to your personal information.
2. What basic security settings should I enable on my smartphone?
To ensure effective public network protection, you should enable features such as Wi-Fi encryption, a strong password for your device, and automatic software updates. Additionally, consider activating your device’s firewall and ensuring that Bluetooth is turned off when not in use to further safeguard your information.
3. How can I tell if a public network is secure?
Before connecting to a public network, look for indicators such as a password requirement, the presence of HTTPS in website URLs, and the use of a Virtual Private Network (VPN) when accessing sensitive information. If a network is open and lacks these features, it may pose a higher security risk.
4. What is a Virtual Private Network (VPN), and should I use one?
A Virtual Private Network (VPN) encrypts your internet connection, providing an additional layer of security when using public networks. It hides your IP address and protects your data from potential eavesdroppers, making it a highly recommended tool for anyone frequently connecting to public Wi-Fi.
5. Are there specific apps I should avoid while using public networks?
Yes, it is advisable to avoid accessing sensitive apps that require personal information, such as banking or shopping applications, while connected to public networks. If necessary, use a VPN to enhance security or wait until you are on a secure, private network to perform such tasks.
6. How often should I update my smartphone’s security settings?
It is essential to review and update your smartphone’s security settings regularly, especially after major software updates or changes in usage patterns. Additionally, it is wise to reassess your settings before connecting to any new public network to ensure maximum protection.
7. What should I do if I suspect that my device has been compromised while using a public network?
If you suspect that your device may have been compromised, immediately disconnect from the public network and turn off your Wi-Fi and Bluetooth. Run a security scan using a reputable antivirus application, change your passwords, and monitor your accounts for any unusual activity. If necessary, consult a professional for further assistance.
