core components of iot systems

Smart Devices & Sensors (The "Things"): These are the actual hardware elements that interact with the environment; actuators carry out physical tasks like opening a valve or turning on a light, while sensors collect data like temperature or wetness.
Connectivity (The Network): This is the communication channel that enables "Things" to communicate with the cloud; several protocols, such as Wi-Fi, Bluetooth (BLE), Zigbee, or Cellular (4G/5G), are used based on range and power requirements.
Data Processing (The Intelligence): Software evaluates the data to make sense of the inputs once it gets to the cloud or a local server. This can involve anything from straightforward tests (is the temperature more than 30°C?) to intricate machine learning patterns.
User Interface (The Control Panel): This is the visible application that allows the human user to engage with the system; it includes mobile apps, web dashboards, or voice assistants that display alarms and allow for manual overrides.

8.	Cost Reduction	Smart building technologies drastically reduce electricity and energy costs by automatically adjusting HVAC and lighting based on occupancy.

Challenges and Risks in IoT Technology

The following are some challenges and risks in IoT technology:

Challenges and Risks in IoT Technology

a) Vulnerability to Cyberattacks: Because many IoT devices lack strong built-in security, DDoS assaults and botnets that may bring down entire networks can easily target them.

b) Data Breaches: Sensitive personal data, such as location, health, and habits, is frequently stored on the cloud due to continuous data gathering, making it susceptible to illegal access.

c) Physical Safety: A hacked gadget (such as a manufacturing robot or smart insulin pump) can result in equipment destruction or direct bodily harm in industrial or healthcare settings.

d) Interoperability: With hundreds of manufacturers employing different protocols (Zigbee, Matter, Wi-Fi), enabling devices from different brands to "talk" to each other remains a huge obstacle.

e) Scalability Issues: As a corporation develops from 10 to 10,000 devices, maintaining upgrades, connectivity, and the sheer volume of data can overwhelm existing IT infrastructure.

f) Supply Chain & Legacy Systems: It can be costly and technically challenging to integrate contemporary IoT sensors with outdated "legacy" equipment in manufacturing.

g) Electronic Waste (e-Waste): The short lifespan of many cheap IoT sensors leads to a significant accumulation of non-recyclable electronic debris and battery disposal difficulties.

h) Informed Consent: It is sometimes unclear to users what data is being collected by "invisible" sensors in public settings, leading to concerns about ongoing surveillance without authorization.

i) Job Displacement: Workers in manufacturing and logistical positions may be displaced as a result of increased automation brought about by Industrial IoT.

IoT Security and Privacy Basics

S.No.	Factors	What?
1.	The Core Principles (The CIA Triad)	Effective security guarantees availability (devices are functional and available when needed), confidentiality (data is encrypted), and integrity (data isn't altered while in transit).
2.	Common Security Layers	Protection is built by Device Authentication (verifying identity), End-to-End Encryption (scrambling data from sensor to cloud), and regular Firmware Updates to remedy emerging software vulnerabilities.
3.	Privacy Concerns for Users	The two main hazards are surveillance, where "always-on" microphones or cameras may record private actions without express agreement, and data profiling, where personal habits are sold to advertisers.
4.	Common IoT Attack Vectors	Hackers commonly exploit systems using Default Passwords that are never changed, Insecure APIs that bridge the device to the internet, and Botnet Recruitment, where thousands of devices are hijacked to launch enormous cyberattacks.

Future Scope of IoT Technology

Artificial Intelligence (AIoT) and 5G connectivity will combine to transform passive sensors into "agentic" devices that can automatically assess data at the edge and carry out real-time activities without human intervention. This will be the future of IoT.
