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

Internet of Things (IoT), as defined by en.wikipedia.org, “describes the network of physical objects, so known as, “things” that are embedded with sensors, software and other technologies that are used to connect and exchange data with other devices and systems over the Internet.” In short, any devices connected in any way to the Internet are part of the IoT. The most expansive segment of IoT relates to the ever-increasing number of smart devices being used 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 of the vast array of connected devices available today.

IoT Security Issues

It should come as no surprise that cyber security 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 to midsized businesses 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 cyber security issues, not only for their business but also for their customers and clients. With each new smart device, the landscape for cybercrime continues to grow.

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.
• Install All Updates – Software developers are constantly working on fixes and patches for their programs. Therefore, it is 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 are thinking of purchasing a smart device, you should investigate whether the device’s software can receive updates. As we discussed for passwords, if the device you are interested in cannot receive software updates, you should be wary of purchasing it.
• Employ Cyber Security Best Practices – Unfortunately, we are potentially the weak link in our IoT. Everyone in your small to midsized business must be on the same page with respect to cyber security. Identifying and standardizing your cyber security protocols and teaching your employees the importance of following them is essential for IoT security.
• Make Cyber Security a Priority – Cyber security must be a way of life for all businesses. For SMBs, lax security can cause devastating consequences, even bankruptcy.

Case Study

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

After a few months, the company was hit with a substantial data breach. The hacker was able to breach their smart system and steal important proprietary information. The CEO didn’t even consider that the attack was launched through the thermostat device hub. When they lost control of their 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 was sold several of their proprietary designs. The cyberthief breached the system, stole the data and sold it to the other company.

The protection of IoT devices is not a simple matter. As our use of online technology and the growing IoT world now encompasses so many areas of our personal and business lives, cybercriminals continue to stay in step and find new ways to attack private and business data. Unfortunately, smaller businesses have neither the time nor the budget for a full-time IT department. However, it is essential to employ IT experts to provide IoT consulting and IoT installation services to assess your cyber vulnerability and help you design the best layers of protection for your hard-earned business data.
