Article summary: Smart office devices connect to your network and rarely get audited. A smart device security audit covers what’s on your network, whether default passwords have been changed, and whether devices are isolated from your core business systems. For most small businesses, it takes a few hours and a simple checklist to close the most common gaps.
Think about the devices in your office that are always on but rarely managed. Things like the printer no one has logged into in months, the smart TV in the boardroom, the HVAC controller the building manager set up when you moved in.
Each one has an IP address, a firmware version, and, in most cases, a default password that was never changed.
For businesses thinking about network security, smart devices are often where the conversation starts. They’re on your network, but they don’t get the same attention as laptops and servers. That gap is where risk tends to accumulate.
A smart device security audit is a practical way to close it.
Why Smart Devices Are a Soft Target
IoT devices mean any piece of hardware that connects to a network beyond traditional computers. They weren’t designed with business security in mind. Most ship with shared default credentials, go months without firmware updates, and end up on the same network as your email, files, and financial data.
Industry research cited in IoT Breakthrough’s 2025 security review found that devices like printers, smart TVs, and IP cameras now appear in a significant share of breach investigations worldwide.
In Canada, the federal Get Cyber Safe program notes that every IoT connection is a new point of access. That means a single compromised device can have downstream effects across your entire infrastructure.
For a small business in the GTA, the practical concern is straightforward. Smart devices are typically the least-managed part of your network, which makes them the easiest targets.
Start With a Device Inventory
Before you check passwords or update firmware, you need a complete list of every connected device in your office.
What to record for each device
For every smart device you find, note:
- Make, model, and physical location
- What it connects to and what it’s used for
- Who (if anyone) manages it
- When firmware was last checked or updated
- Whether it sits on your main network or a separate one
The devices most offices forget
Most businesses track laptops and phones. Smart devices get overlooked.
Your inventory should include:
- Printers and multifunction devices
- Smart TVs, displays, and conferencing hardware
- HVAC controls and smart thermostats
- IP security cameras and door access systems
- Wireless speakers and VoIP phones
- Any device with a Wi-Fi or Ethernet connection
If you’re unsure what’s connected, your router or firewall’s device list is a good starting point. A basic network scan can surface devices that have been forgotten entirely.
The Smart Device Security Audit Checklist
With your inventory in hand, work through these four areas for every device.
Change default passwords
Most IoT devices ship with a manufacturer default, often something like “admin,” “password,” or the device serial number. These credentials are publicly listed and actively targeted by automated bots that scan the internet continuously.
Change every default password to something unique. Where possible, use a centralised credential system or password manager to track them. If a device doesn’t allow you to change its password at all, note it as a priority risk.
Check and update firmware
Log into each device’s admin interface and compare the current version to what the manufacturer lists as current. If a device hasn’t received a security update in over a year or if the manufacturer no longer issues them, treat it as a liability.
The same habit applies across all your systems.
Keeping software and firmware current is one of the most effective and low-cost controls any business can apply.
Verify network placement
Smart devices should not share a network with your business data.
The standard control is network segmentation. Placing IoT devices on a separate VLAN (virtual local area networks) so that a compromised device can’t reach your files, email server, or financial systems.
If your printers and cameras currently sit on the same network as your workstations, correcting this should be near the top of your list.
Remove devices you no longer use
Devices that are plugged in but unused are still active on your network and still vulnerable. Anything you’re not actively using should be disabled and, where possible, removed. Before disposal, perform a factory reset to clear stored credentials and network settings.
Building a Repeatable Routine
A single smart device security audit is a good start. What actually keeps you protected is repeating it regularly.
A quarterly check is realistic for most small offices. A simple one-page document that lists your devices, names an owner for each, and sets an update schedule gives you accountability without complexity.
Canada’s Get Cyber Safe program recommends integrating IoT security into your broader cybersecurity policy rather than managing it as a separate task. Pairing this with consistent network monitoring and maintenance turns a one-time review into an ongoing practice.
Tighten Up Your Office Network
Smart devices are now standard in every office environment. Most small businesses in the Greater Toronto Area manage them informally. And the gap between informal and secure is where incidents happen.

Article FAQs
What is a smart device security audit?
A smart device security audit is a structured review of every internet-connected device in your office beyond traditional computers and phones. It checks what’s on your network, whether default passwords have been changed, whether firmware is current, and whether devices are properly isolated from your core business systems.
What happens if a smart device is compromised?
A compromised device can be used to monitor network traffic, launch attacks on other connected systems, or provide a foothold for accessing your business data. If devices aren’t segmented from your main network, a breach starting at a printer or thermostat can reach your most critical systems.
Are there Canadian regulations that apply to IoT security?
There is no single law mandating IoT security for all Canadian businesses, but PIPEDA (the Personal Information Protection and Electronic Documents Act) requires organisations to protect personal information. A compromised device that exposes customer data could constitute a reportable breach. Sector-specific rules such as PHIPA for health information or PCI DSS for payment card data may also apply.
