- The definition and core concept of the Internet of Things (IoT)
- Key characteristics and capabilities of IoT “things”
- IoT network types, from small-scale to specialized networks
- Common IoT protocols and interfaces
- IoT architectural models and connectivity methods
- Real-world IoT applications and benefits across multiple sectors
- Security threats and vulnerabilities affecting IoT devices, networks, and data
- Best practices and preliminary recommendations for securing IoT systems
- The IoT consists of an evolving set of cyber and/or physical entities and networks.
- “Things” are devices that can be connected, interacted with, and controlled.
- Core capabilities include: network connectivity, data sensing and storage, computation, communication, autonomous operation, and response to commands.
- Small-Scale Networks: PANs (Personal Area Networks) and BANs (Body Area Networks), e.g., wearables like Fitbits or pacemakers.
- Localized Networks: LANs (Local Area Networks), WLANs (Wireless LANs), and HANs (Hospital/Home Area Networks).
- Large-Scale Networks: MANs (Metropolitan Area Networks) and WANs (Wide Area Networks).
- Specialized Networks: M2M (Machine-to-Machine) networks and Wireless Sensor Networks.
- IoT leverages standard networking protocols, as well as IoT-specific protocols:
- RFID (Radio Frequency Identification)
- MQTT (Message Queuing Telemetry Transport)
- Bluetooth Low Energy (BLE)
- Other protocols for IoT-specific communication
- Direct Device-to-Device Communication: Example: smart bulb communicates directly with a switch.
- Local Hub Connectivity: Example: smoke alarm sending data to a local laptop.
- Gateway-to-Cloud Communication: Example: devices connected via a phone or gateway for cloud-based processing and analysis.
- Smart Environments: Smart cities (e.g., Singapore, Barcelona), smart homes, and university research labs.
- Daily Life: Transportation (autonomous vehicles), personal assistants, access control systems, and smart retail (e.g., smart fridges).
- Health and Wellness: Remote monitoring, elderly “aging in place” support, and wearable fitness trackers.
- Industry and Finance: Factory floor automation via sensors, financial services personalization, and insurance risk management.
- Physical or logical infrastructure theft or tampering
- Data leakage and breaches
- Authentication bypass or weak credential management
- Denial of Service (DoS) attacks
- Firmware malware and unpatched vulnerabilities
- Homogeneity of devices increasing systemic risk
- Challenges with accountability in autonomous systems (e.g., self-driving vehicles)
- Connect devices selectively and avoid unnecessary network exposure
- Segment networks (e.g., separate IoT devices from main networks)
- Verify and adjust default security settings on devices
- Securely dispose of old devices and sensitive data
- Minimize unnecessary communication points to reduce attack surfaces
