8 Ways to Secure Your Home Fibre Connection
Your home fibre connection is fast and reliable, but it’s also a target for cyber threats. Securing it doesn’t have to be complicated. Here’s how you can protect your network and keep your personal data safe:
Set strong, unique passwords for your Wi-Fi and router.
Enable WPA3 encryption to block common hacking methods.
Update your router firmware and connected devices regularly.
Turn on your router’s firewall and consider using a VPN for extra privacy.
Physically secure your equipment to prevent tampering.
Monitor network activity to spot unusual behaviour.
Teach your family about online safety to avoid common scams.
Choose a reliable fibre provider that prioritises security.
These steps work together to reduce risks like data theft, device hijacking, and bandwidth misuse. Start by changing default passwords and enabling WPA3 encryption for immediate protection. Then, stay vigilant by keeping your devices updated and monitoring your network. A secure fibre connection keeps your household safe in an increasingly connected world.
1. Create Strong Passwords for Your Wi‑Fi and Router
Routers often come with default login credentials - commonly something like "admin" for the username and "password" for the password. These defaults are widely known and easy to find online, making your network vulnerable. Changing these default settings should be your first step in protecting your network. Without doing so, others could access your network, steal your bandwidth, or even use your devices in a denial-of-service attack.
Set up separate, strong passwords for both your router admin and Wi‑Fi. This way, even if one gets compromised, the other remains secure.
For your Wi‑Fi, aim for a password that’s at least 20 characters long. Include a mix of upper- and lower-case letters, numbers, and special symbols. Avoid using common words, predictable phrases, or personal information like your name or address. If you prefer something easier to recall, opt for a secure but memorable passphrase.
A password manager can help by generating and securely storing these complex passwords, so you don’t have to memorise them all.
Keep your router admin credentials private and only share your Wi‑Fi password with trusted household members. Make it a habit to update both passwords regularly.
To take your network security a step further, enable WPA3 encryption. This provides an additional layer of protection for your connection.
2. Turn On WPA3 Network Encryption
WPA3 (Wi‑Fi Protected Access III) has been around since 2018 and became mandatory in July 2020 [8]. Unlike the older Pre-Shared Key method, WPA3 uses Simultaneous Authentication of Equals (SAE), which makes guessing your Wi‑Fi password far more challenging. Attackers must interact with your network for every single guess, effectively blocking offline dictionary attacks and significantly limiting brute-force attempts.
Another advantage of WPA3 is its forward secrecy. This ensures that even if someone manages to get hold of your current password, any previously intercepted data remains safe. Each session generates unique encryption keys, adding an extra layer of security. Additionally, Protected Management Frames (PMF) safeguard communications between your devices and the router, helping to prevent spoofing, denial-of-service, and man-in-the-middle attacks [8].
Want to check if your router supports WPA3? Look for the "Wi‑Fi CERTIFIED™ WPA3™" label on the device or its packaging. Any router released after July 2020 with this certification should support WPA3 [9]. Most modern routers include this feature as standard.
If your router is compatible, here's how to enable WPA3:
Open your web browser and type your router's IP address (commonly 192.168.1.1 or 192.168.0.1) into the address bar.
Log in using your router's credentials.
Navigate to the "Wi‑Fi" or "Wireless" settings section.
Enable WPA2/WPA3 Mixed Mode if you have older devices that don’t support WPA3, ensuring compatibility while still securing newer devices [10].
After enabling WPA3, make it a habit to update your router’s firmware regularly. These updates often include security patches, helping you maintain the benefits of WPA3 encryption.
3. Keep Router Firmware and Devices Updated
Your router's firmware is essentially the brain behind your home network, managing how data flows between devices. Manufacturers frequently release updates to address security vulnerabilities, ensuring your network remains protected. Ignoring these updates can leave your router exposed to potential attacks, giving hackers an open door to your home network.
Does your ISP handle updates? If your router comes from a New Zealand ISP, there’s a good chance they manage updates remotely. This often includes automatic firmware patches or closing off risky ports. It’s worth contacting your provider to confirm what security measures they take and whether they handle these updates on your behalf.
For self-managed routers: If you’ve purchased your own router, the responsibility for updates falls on you. Many modern routers are equipped to update automatically, but it’s always a good idea to double-check. You can manually check for updates by logging into your router’s admin panel using its IP address (e.g. 192.168.0.1 or 192.168.1.1). To access the admin panel, you’ll need the router’s admin username and password, which are often found in your provider’s support materials, setup emails, or by reaching out to their helpdesk.
Don’t forget your devices: It’s not just your router that needs attention. Keeping all your connected devices updated is equally important to patch security gaps.
When to replace outdated hardware: If your router is several years old and no longer receives firmware updates, it’s time to upgrade. Outdated routers without ongoing support can put your entire network at risk. Consider investing in a newer model or discussing upgrade options with your ISP.
4. Install a Firewall and Use a VPN
A firewall acts as a gatekeeper for your internet connection, monitoring all incoming and outgoing traffic on your router [6]. It blocks unauthorised access while allowing legitimate data to pass through, helping to shield your network from potential cyber threats [3][6].
Most modern routers come with a built-in firewall, complete with preset rules to manage traffic [6][11]. However, some routers have this feature turned off by default. To ensure your network is secure, check your router's admin panel and confirm that the firewall is enabled. Additionally, lock down your router's administrative access so it can only be managed from within your home network [6]. If your router doesn't include a built-in firewall, you might want to install firewall software on your devices or consider upgrading to a router that offers integrated protection [5].
Once your firewall is set up, take security a step further by encrypting your online activity with a VPN. A VPN creates a secure, encrypted tunnel for your data [5]. This ensures that any information you send or receive remains private, making it particularly useful for sensitive tasks like online banking or accessing work files remotely - even if you're already on a secure home fibre connection.
When used together, a properly configured firewall and an active VPN form a strong defence - blocking unauthorised access while keeping your data encrypted and secure.
5. Protect Your Fibre Equipment Physically
Digital security is essential, but don’t overlook the importance of physically safeguarding your fibre equipment. Devices like your router, modem, and fibre connection points can become easy targets if left exposed to tampering or unauthorised access.
The placement of your equipment plays a key role in keeping your network secure. Make sure your router is in a central and visible spot in your home. Avoid hiding it in cupboards or placing it near windows, as these locations can make it easier for someone to interfere with it [12] [7].
"Unsecured Wi‑Fi is like an unlocked front door - it might look 'closed' at first glance but anyone can access it if they just try." - Crissy Joshua, Staff Cybersecurity Editor, Norton [13]
To add another layer of protection, limit who can physically access your devices. Place them in secure areas that aren’t easily reachable by visitors. This way, you’ll be able to spot any signs of tampering more quickly and prevent unauthorised changes to your network setup.
6. Check Network Activity for Unusual Behaviour
Keeping an eye on your network activity is a smart way to catch potential threats early. It works hand in hand with the other security measures we've discussed.
Devices like Fingbox make this process simple. Fingbox connects directly to your router and, through its app, lets you see who's connected to your network. It can also flag unknown or unauthorised devices and give you the option to block them immediately. On top of that, its bandwidth monitoring feature helps you spot unusual data usage, which could point to a security concern. Handy, right? [15]
Some routers take things a step further with Deep Packet Inspection (DPI). DPI provides detailed insights into how your network is being used. When paired with strong passwords and encryption, it becomes a key part of a well-rounded defence plan. [16]
That said, keep in mind that not all tools are focused on security - some are more about improving performance. So, choose your tools wisely. [14][17]
With high-speed, always-on fibre connections, regular monitoring becomes even more crucial. Make it a habit to review your connected devices each week, keeping an eye out for anything odd in data usage or device activity. A little vigilance can go a long way.
7. Teach Your Family About Internet Safety
Having a secure technical setup is just one piece of the puzzle. To truly protect your home fibre network, it’s essential to educate your family about staying safe online. Even the most secure connection can be compromised if someone in your household falls victim to an online threat. That’s why teaching your family how to spot and avoid these dangers is so important.
Cyber incidents have shown how easily phishing scams and credential theft can target unsuspecting users. These are some of the most common threats, and every family member should know how to identify and steer clear of them.
Start by teaching your family to carefully examine unexpected messages or emails before responding. Phishing scams often create a sense of urgency to push people into quick action, so it’s crucial to encourage a “pause and think” approach. Remind them to double-check details and confirm anything suspicious with a trusted person before taking any steps [3].
Another essential step is enabling two-factor authentication (2FA) on key accounts. Take the time to show your family how to set it up for their email, social media, and banking accounts. This adds an extra layer of security, even if their passwords are compromised.
Set clear rules about sharing your Wi‑Fi password. Limit access to trusted household members and make sure they understand that sharing the password with others can lead to security risks.
Just as technical measures safeguard your network, informed family members are the final link in the chain. To help with this, the National Cyber Security Centre’s "Own Your Online" platform provides practical resources for understanding and managing online risks [4]. CERT NZ also offers valuable advice to keep your household safe online [1].
Having regular family discussions about new online threats and best practices can go a long way in keeping everyone informed and secure. As the digital landscape evolves, these conversations ensure your household stays one step ahead.
8. Pick Trusted Fibre Internet Providers
When selecting a fibre internet provider, it's crucial to look beyond just speed and price - network security should be a top priority. While securing your own devices is important, the quality of security measures implemented by your Internet Service Provider (ISP) plays a significant role in protecting your network.
Fibre providers often supply routers or modems that act as the gateway to your home network[6]. When researching potential ISPs, ask if they handle remote router management, such as applying security patches automatically and closing vulnerable ports. These proactive measures by your provider can significantly enhance the security of your home network and work hand-in-hand with the steps you take to secure your devices.
Another feature to look for is the ability to monitor your data usage through an online account portal[2]. Reliable ISPs typically pair this with a knowledgeable support team that can assist with tasks like router settings, password updates, and addressing general security concerns[3].
Make sure the equipment provided by your ISP is modern and secure. If you're using an older router that no longer receives updates, it’s worth discussing upgrade options with your provider[6]. Outdated hardware can leave your network exposed to potential risks.
If you ever encounter security issues or have concerns, don’t hesitate to reach out to your ISP’s support team[2][3]. Choosing a trustworthy provider not only strengthens your network’s security but also gives you peace of mind knowing your system is in capable hands.
