IoT Network Security: Do I Need Security for IoT Devices?

The Internet of Things (IoT) describes any devices connected in any way to the internet not including computers or phones. The most expansive segment of IoT relates to the ever-increasing number of smart devices coming online for commercial and personal use.

Worldwide, there are now billions of physical devices connected to the internet, storing and sharing data. Smart lightbulbs, smart televisions, app-controlled toys, smart thermostats, self-driving vehicles and smart vacuum cleaners are just a few examples. They all raise questions about IoT network security or the need for IoT consulting and IoT installation services to protect business data and secure the company network from cybercriminals that may use IoT devices to gain access.

Q: Why is cybersecurity important for small businesses using IoT devices?

A: These devices often serve as entry points for hackers. Unlike traditional IT systems, IoT devices, like smart thermostats, cameras, or connected printers, are not always equipped with strong security features. If compromised, these devices can give attackers access to sensitive company data or networks. For small businesses, a single breach can lead to significant financial losses, reputational damage and ongoing legal liabilities. Securing IoT devices is essential to protect the integrity and continuity of business operations.

What Are the Main IoT Security Issues?

It should come as no surprise that cybersecurity is one of the most significant issues related to IoT. Hackers love finding new ways to use the internet to breach private data. IoT devices offer many new channels and endpoints through which cybercriminals can gain access.

Small and midsized businesses (SMBs) that manufacture products use more and more sensors and software to track product performance, make their supply chains more efficient and other internet-driven features. However, any SMB using IoT-connected devices for any purpose must address the IoT cybersecurity issues, for their business and for their clients. With each new smart device, the landscape for IoT network security grows.

However, there are some simple steps a small to midsized business can take to employ IoT technology safely:

• Do Not Use Default Passwords – Many people connect devices right out of the box. Part of that process should include immediately changing the default passwords preloaded by the manufacturer. Hackers studying ways to breach the security of smart devices can use default passwords to gain access to them. Avoid purchasing devices that do not allow you to change the default passwords, and consider using an IoT installation service
• Install All Updates – Software developers are constantly working on fixes and patches for their programs, so it’s essential to install all system and software updates on a timely basis. Otherwise, you might experience a cyberattack through your connected devices that you could’ve avoided. If you’re thinking of purchasing a smart device, you should investigate whether the device’s software can receive updates. As with passwords, if the device you’re interested in cannot receive software updates, you should be wary of purchasing it
• Employ Cybersecurity Best Practices – People are the weakest link in IoT network security. Your employees must be on the same page with respect to security for IoT devices. Identifying and standardizing your cybersecurity protocols and teaching your employees the importance of following them is essential for IoT security
• Make Cybersecurity a Priority – Cybersecurity must be a way of life for all businesses. For SMBs, lax security can cause devastating consequences, even bankruptcy.

Q: What are some common IoT security issues?

A: Common risks include weak passwords, outdated firmware and unsecured network connections. Many IoT devices come with default login credentials that are rarely changed, making them easy targets. In addition, manufacturers may stop updating older models, leaving known vulnerabilities unpatched. Small businesses may also fail to segment their networks properly, allowing an infected IoT device to provide attackers with access to more critical systems like point-of-sale machines or customer databases.

Case Study

The CEO of a small but successful manufacturing company thought it would be great to upgrade the offices and warehouse by installing a “smart” system to control all the lighting and heating. Everything seemed to be working perfectly, and the employees appreciated the modernized offices and warehouse. Unfortunately, the excitement of having more extensive control over these environmental elements blinded the executive to investigating the IoT security issues presented by a smart system.

After a few months, the company was hit with a substantial data breach. The hacker was able to breach the smart system and steal important proprietary information. The CEO didn’t even consider that the attack was launched through the thermostat device hub. When the company lost control of its air conditioning and called a repair service, the technician told them the problem was a software issue. The CEO was baffled. She never considered the possibility of a cyberattack through their newly expanded IoT. Three weeks later, she received a tip that one of their close competitors acquired several of their proprietary designs. The cyberthief breached the system, stole the data and sold it to another company.

How Do You Protect Your IoT Devices from Cyberattacks?

Security for IoT devices is not a simple matter. Cybercriminals continue to find new ways to attack private and business data. Unfortunately, smaller businesses don’t have the time or budget for a full-time IT department. IT experts can provide IoT consulting and IoT installation services that will reduce the risks associated with connected devices.

IT security firms work with small and midsized businesses to establish cybersecurity best practices that help ensure your confidential data is secure. They can provide IoT consulting and IoT installation service for all your devices.
