The Internet of Things (IoT) has revolutionized the way small and midsize businesses (SMBs) operate. From smart thermostats optimizing office temperatures to connected security cameras monitoring your premises, IoT devices bring convenience, efficiency, and cost savings. But with great connectivity comes great responsibility—because every internet-connected device is a potential target for cyber threats.
For SMBs, ensuring IoT security isn’t just about protecting individual gadgets; it’s about safeguarding business data, customer trust, and operational continuity. So, how do you keep your smart devices from becoming liabilities? Let’s break it down into essentials that are practical, effective, and—most importantly—manageable for your business.
Know What’s Connected to Your Network
Would you let a stranger walk into your office and start rummaging through your files? Probably not. Yet, many businesses unknowingly allow unsecured IoT devices to do just that—connect to their network without proper oversight.
Start by auditing every device linked to your network. This includes obvious ones like printers and security cameras but also less obvious ones like smart light bulbs or even coffee machines. A regularly updated inventory ensures that no rogue or forgotten device becomes an easy backdoor for cybercriminals.
Change Default Passwords Immediately
Many IoT devices come with factory-set passwords that are widely known (or easily guessed). Leaving them as-is is like keeping your front door’s default lock code—it won’t take much effort for an attacker to break in.
The first step after installing any new IoT device? Change the default login credentials to something strong and unique. Better yet, use a password manager to generate and store complex passwords so you’re not tempted to default to “Password123” (we’ve all been there).
Segment Your Network
Think of your business network as a house with multiple rooms. Do you really want your smart fridge having the same level of access as your payroll system? Probably not.
By segmenting your network—creating separate lanes for different devices—you minimize risk. Keep IoT devices on a dedicated network that’s separate from critical business operations. That way, if a hacker compromises a smart thermostat, they won’t be able to move laterally and access sensitive company data.
Keep Firmware Updated
IoT manufacturers regularly release firmware updates to fix security vulnerabilities. But if your devices aren’t set to update automatically (or you ignore those alerts), you’re leaving an open door for attackers.
Make firmware updates part of your regular IT maintenance routine. If a device no longer receives updates from the manufacturer, consider replacing it—it’s like keeping a security system with outdated software.
Limit Device Permissions
Not every device needs full admin privileges. In fact, most don’t. Many IoT devices come with more access rights than necessary, which can lead to security risks if they are compromised.
Restrict permissions based on the principle of least privilege—giving devices and users only the access they absolutely need. For instance, a smart lock should be able to control door access but shouldn’t have permission to modify your entire network configuration.
Enable Multi-Factor Authentication (MFA) Where Possible
If an IoT device or its management system offers multi-factor authentication (MFA), enable it. MFA adds an extra layer of security by requiring a second form of verification (such as a text code or authentication app) before granting access.
Think of it as having a deadbolt on your digital front door—it makes unauthorized access significantly more difficult.
Monitor for Suspicious Activity
Even with security measures in place, it’s essential to keep an eye on network activity. Unusual spikes in data usage, connections from unknown locations, or devices acting erratically can all be red flags.
A robust network monitoring solution can alert you to potential threats before they escalate. If you’re unsure how to set up or manage one, working with an expert in IT consulting in Dallas & Denver can help you implement proactive security measures.
Train Employees on IoT Security
Technology alone can’t solve security issues—your team plays a crucial role too. Many security breaches occur due to human error, like plugging in unauthorized devices or failing to recognize phishing attempts related to IoT controls.
Regular cybersecurity training helps employees understand the risks and best practices for keeping devices secure. A little awareness goes a long way in preventing costly security incidents.
