Internet of Things (IoT) technology continues to disrupt both the consumer and enterprise sectors and as new use cases are found, its adoption is only expected to grow. That includes many powerful applications in physical security, access control, and operations management.
And yet many Internet of Things security risks remain.
The very network connections that drive the IoT are also its greatest liability, opening previously-secure physical infrastructure to remote network-based attacks. But with a little insight and careful planning, IoT security technology can be effectively deployed in any organization.
What is IoT?
The Internet of Things is the latest generation of physical infrastructure embedded with Internet connections. Think of security cameras that can email homeowners motion-detected video clips on their own. Or asset management lockers that notify supervisors when sensitive equipment isn’t returned at the end of a shift.
Why IoT System Security Matters
IoT technology is spreading fast. The research firm IoT Analytics estimated that 14.3 billion IoT devices were used worldwide in 2022. That figure is expected to grow to 29 billion by 2027.
The threats against them have increased too. In a few short years, IoT attacks have gone from solely a national intelligence agency tool to standard kit for hackers. In fact, one of the largest ‘denial of service’ attacks in Internet history and the single largest cyber-attack of 2016 was perpetrated by novice hackers targeting IoT security cameras, printers, and even baby monitors. Using a network of these infected devices, the attackers were able to disrupt Internet service for much of the eastern United States.
Today there are even publicly available IoT device search engines that let anyone, security professionals and hackers alike, find devices anywhere in the world. Internet of Things threats now target physical infrastructure. Attacks on physical infrastructure no longer necessarily come through the front or back door. Instead, they can now come from another hemisphere.
How Do IoT Security Solutions Work?
IoT technology is the glue that holds together modern, networked IoT security solutions. They connect to wider security and access control infrastructure in several important ways.
IoT technology allows security systems to self-monitor and collect data about themselves. That is often performed over a wireless communication standard in security systems, like radio frequency identification (RFID). RFID is a short-range wireless standard most often used for computer-to-computer communication. One great thing about RFID Internet of Things sensors is that each tagged device has a unique identity in the security system so that you can track assets over their entire lifecycle in your organization.
Data collected from the IoT sensor network feeds back to a central computer system. Data is stored for reporting and analysis. You can also configure the management system to trigger responses to events you specify. The management system can relay this information to human operators.
Controller components take action in response to the management computer’s decisions. For example, in an IoT security solution could be the compartments in an asset management system that sends an alert to a supervisor if someone returns a kit with a missing component not read by the locker’s content surveillance system. Or it could be the locking slot in a key cabinet that won’t release a vehicle key if the previous user reported a serious mechanical fault.
Analytics: The Key Benefit of IoT Security Solutions
Analytics is the process of gathering, interpreting, and deriving meaningful insights from data to support decision-making. It involves using statistical analysis, data mining, predictive modeling, and machine learning techniques to discover actionable insights you might never notice through manual, human observation.
The greatest benefit of IoT security solutions is their data-gathering capabilities to support operational and strategic analytics. Leveraging IoT analytics from smart key, asset, and access control systems improves organizations in many ways.

IoT Security Issues to Beware Of
IoT technology is powerful, but it overlaps our physical and network security environments in ways that can be exploited. This is particularly important to consider as businesses deploy more and more IoT systems within their physical security infrastructure. Deployed improperly, these security systems can become vulnerabilities themselves.
If your business uses or plans to use IoT systems, it pays to know the tactics attackers might use to target them.
IoT is Driving Security Convergence
If there weren’t enough indicators already, IoT convergence has become a necessary security approach, as IoT technology has literally converged our physical and network infrastructure.
Going hand-in-hand with such a converged program comes a need for increased communication and security education throughout your organization. IoT technology can turn any employee’s mobile device into a potential threat. Therefore, your organization must know and participate in your security efforts.
And when in doubt, get expert assistance evaluating and deploying new systems. IoT technology is powerful but complex. Making sure it’s used both effectively and securely within your organization can require insight from dedicated experts.
