The Connected Office: Why IoT Devices Are a Security Risk Your Business Cannot Ignore
Walk through any professional services office in Christchurch and count the devices connected to your network. The wifi printer. The smart TV in the boardroom. The wireless EFTPOS terminals. The security cameras. The keypad on the front door. Every one of those devices is a computer, and most of them were never designed with security as a priority.
This is the IoT problem in plain terms. IoT stands for Internet of Things - it just means any device that connects to the internet that isn't a traditional computer or phone. These devices tend to ship with weak default passwords, receive software updates rarely or never, and send data across your network with little or no protection. From a security perspective, each one is a potential door into your business. Attackers know this, and they actively scan for these devices because they are often the easiest way in.
The real cost is not the device itself being compromised. It is what happens next. Once an attacker is inside one device on your network, they can often move across to other systems - your client files, your billing software, your email. For a practice handling sensitive client information, that is a serious problem. Under the NZ Privacy Act 2020, a breach involving client data is not just an IT inconvenience. It is a notifiable event, with obligations to report to the Office of the Privacy Commissioner and potentially to affected clients as well.
The good news is that basic discipline goes a long way. The devices on your network should be separated from your main business systems - a technique called network segmentation. This means if a printer or a smart TV is ever compromised, the attacker does not automatically have access to everything else. Devices should have their default passwords changed before they go live. Software updates should be applied when available. And honestly, any device that does not need to be connected to the internet probably should not be. Understanding why most breaches are entirely preventable is a good place to start when thinking about how attackers exploit weak credentials across all kinds of devices.
What this looks like in practice is a business where someone has actually mapped what is on the network and made deliberate decisions about each device. Not a free-for-all where staff connect whatever is convenient. When your IT is managed properly, those decisions are made for you, and you are not left finding out about a problem after it has already caused damage. If you want to understand what good looks like for a professional services practice, managed IT support for professional services is worth understanding before you need it.
The starting point for most businesses is simply knowing what is actually connected to their network. Most practice managers have no idea, and that is not a criticism - it is just not something anyone told them to track. A proper review will surface devices that should not be there, flag ones with known vulnerabilities, and make sure everything is configured securely. Attackers rely on businesses remaining unaware - learning about the ways hackers get into business accounts can help you understand why a thorough network review matters.
