What is the Internet of Things?
The Internet of Things represents a fundamental shift in how technology interacts with the physical world. At its core, IoT is a vast network where everyday objects—from refrigerators to factory equipment—are equipped with sensors, software, and internet connectivity that allow them to collect data, communicate with other devices, and perform actions based on that information.
Think of IoT as giving inanimate objects a digital nervous system. A traditional thermostat simply maintains temperature based on manual settings. An IoT-enabled smart thermostat learns your schedule, detects when you're away through your smartphone's location, adjusts settings based on weather forecasts, and even identifies energy waste—all automatically.
According to IoT Analytics, the number of connected IoT devices reached 21.1 billion by the end of 2025, representing 14% year-over-year growth (IoT Analytics, 2025). This explosive expansion reflects how IoT has moved from experimental technology to essential infrastructure across virtually every industry.
The World Health Organization reports that more than 40% of hospitals in high-income countries now utilize IoT-enabled patient monitoring systems, significantly improving early diagnosis and treatment adherence (Market Data Forecast, 2024). In manufacturing, IoT sensors generated 14.2 zettabytes of data in 2023, projected to reach 79.4 zettabytes by 2025, according to the International Data Corporation (Market Data Forecast, 2024).
What makes IoT transformative isn't just connectivity—it's the intelligence these devices gain from their interconnectedness. When millions of smart sensors share data through cloud platforms and AI algorithms, they create systems that can predict equipment failures before they happen, optimize traffic flow in real-time, and personalize healthcare at unprecedented scales.
The technology encompasses three key elements: physical devices with embedded sensors, network connectivity (Wi-Fi, cellular, Bluetooth, or specialized protocols like LoRaWAN), and data processing platforms that turn raw sensor readings into actionable insights.
The Origin Story: How IoT Was Born
The Internet of Things didn't emerge overnight—it evolved from decades of technological innovation, but the term itself has a precise origin point.
In 1999, British technology pioneer Kevin Ashton coined the phrase "Internet of Things" while working as an assistant brand manager at Procter & Gamble. During a presentation about using RFID (Radio-Frequency Identification) technology to improve supply chain management, Ashton linked the concept of RFID-tagged products to the internet, creating a phrase that would define an entire technology sector (History of Information, 1999).
Ashton's original vision, as he later explained, addressed a fundamental limitation: "Today computers, and, therefore, the Internet, are almost wholly dependent on human beings for information. Nearly all of the roughly 50 petabytes of data available on the Internet were first captured and created by human beings by typing, pressing a record button, taking a digital picture or scanning a barcode. If we had computers that knew everything there was to know about things—using data they gathered without any help from us—we would be able to track and count everything, and greatly reduce waste, loss and cost" (Dataversity, 2022).
Following his presentation, Ashton cofounded the Auto-ID Center at MIT in 1999 alongside professors Sanjay Sarma and Sunny Siu, along with researcher David Brock. The center's mission was creating a global standard system for RFID technology (Wikipedia, 2025). Under their leadership, the Auto-ID Center developed the Electronic Product Code (EPC), a global RFID-based identification system intended to replace traditional UPC barcodes.
However, the conceptual foundations of IoT predated Ashton's terminology. One of the earliest examples of an IoT device appeared in the early 1980s: a Coca-Cola machine at Carnegie Mellon University. Local programmers connected to the refrigerated appliance through the internet to check if drinks were available and cold before making the trip to purchase one (Dataversity, 2022).
In 2002-2003, Walmart and the U.S. Department of Defense became the first large organizations to embrace Ashton's model of tracking inventory using tagging, RFID, and IoT principles. Walmart required its top 100 suppliers to place RFID tags on cases and pallets by 2005, leading to decreased merchandise theft and reduced annual labor requirements (HQ Software Lab, 2025).
The term gained mainstream traction throughout the 2000s as wireless connectivity became cheaper and more ubiquitous. By 2010, with the growth of machine-to-machine communication, the number of IoT devices exceeded the global population for the first time (Testbook, 2025).

Attacks on IoT endpoints jumped 107% year-over-year in early 2024, with average attacks lasting more than 52 hours per week (GAP, 2025). The global IoT ecosystem faces an average of 10 attacks every 24 hours on home network devices, with Bitdefender smart home security solutions blocking an average of 2.5 million threats daily, or roughly 1,736 threats per minute (NETGEAR, 2024).
According to Kaspersky, in 2024, more than 1.7 billion cyberattacks on IoT devices were detected, with over 850,000 attacks launched worldwide. The UAE reported 45,708 IoT attacks, representing a 54% increase from the previous year (eInfochips, 2025).
Financial Impact: The average cost of an IoT-related data breach in 2025 is $357,000, with enterprise cases exceeding $1.8 million. Healthcare organizations face particular risks with attacks on medical devices averaging $10 million per breach (CompareCheapSSL, 2025).
Forrester data showed 34% of IoT-involved breaches cost between $5-10 million, a stark reminder of potential damage scale (GAP, 2025). Retailers lost over $20 billion to IoT cyberattacks in 2024 (JumpCloud, 2025).
Primary Threat Vectors
IoT Botnets and DDoS Attacks: IoT botnets remain a dominant threat, where millions of poorly secured devices—including cameras, routers, and sensors—are infected with malware to form massive attack networks. About 35% of global DDoS attacks today originate from IoT botnets, capable of taking down corporate websites, partner systems, or even public infrastructure with terabit-scale floods (GAP, 2025).
In November 2024, a malicious actor called "Matrix" turned IoT devices into a global botnet used to carry out distributed denial-of-service attacks, targeting connected devices with known vulnerabilities and deploying Mirai botnet malware (Asimily, 2025).
In July 2025, Google, in partnership with Human Security and Trend Micro, disclosed BadBox 2.0, the largest known botnet of internet-connected TVs (Asimily, 2025).
Weak Authentication: Default passwords and weak credentials remain far too common. Shockingly, one in five IoT devices continues to ship with factory-default login settings. About 82% of consumer IoT devices lack proper access controls or password protection (CompareCheapSSL, 2025).
Unpatched Vulnerabilities: IoT devices are notoriously slow to patch, often because they lack automated update mechanisms or require manual intervention. Unpatched firmware is responsible for 60% of IoT security breaches, according to the IoT Security Foundation's 2024 report (Microminder, 2025).
In 2024, attackers continued to exploit CVE-2023-1389, a known command-injection flaw in TP-Link routers, affecting over 21% of SMBs. Since IoT firmware can linger unpatched for years, adversaries routinely scan for these weaknesses (GAP, 2025).

Q13: How does IoT impact energy consumption and sustainability?
IoT can significantly reduce energy consumption through optimization. Barcelona's smart lighting significantly lowered energy costs. Dutch IoT-driven greenhouses reduced energy consumption by 50% (Invade Agro, 2025). However, the devices themselves consume power, and data centers processing IoT data have environmental footprints. Green IoT focuses on energy-efficient designs, renewable power sources, and optimizing overall system efficiency. The net impact is typically positive when IoT enables broader resource optimization.
Q14: What is the role of standards in IoT, and why are they important?
Standards enable interoperability between devices from different manufacturers, ensure security baselines, facilitate large-scale deployments, and reduce vendor lock-in. Key standards include MQTT and CoAP for communication, NIST IoT Cybersecurity Framework for security, and industry-specific standards like HL7 FHIR for healthcare. Organizations implementing IoT security frameworks reduce cyberattack risks by 60% (JumpCloud, 2025).
Q15: How can organizations ensure IoT implementations comply with privacy regulations?
Compliance requires data minimization (collect only necessary data), anonymization and encryption, clear privacy policies, consent mechanisms, data retention limits, and regular audits. Healthcare organizations must comply with HIPAA, European organizations with GDPR, and California businesses with CCPA. Privacy-by-design principles should be integrated from the start, with legal review of data handling practices and third-party vendor agreements.
