Types of IoT attacks
1. Physical Attacks
Physical attacks exploit direct access to IoT devices to manipulate hardware or
introduce vulnerabilities. These attacks include:
Node Tampering: Physical interference with device components to alter functionality
or extract sensitive data.
RF Interference on RFID: Disrupting Radio Frequency (RF) communication in RFID
systems to prevent proper operation or extract information.
Malicious Node Injection: Adding unauthorized devices to the network to intercept
or manipulate data.
Malicious Code Injection: Introducing harmful code at the hardware level to
compromise the system.
Physical Damage: Intentionally damaging devices to disrupt operations.
Sleep Deprivation: Draining battery life by forcing devices to stay active longer than
intended.
Social Engineering: Manipulating individuals to gain access to devices or
information.
2. Software Attacks
These attacks target vulnerabilities in IoT software or applications, including:
Malicious Scripts: Injecting scripts to perform unauthorized actions.
Phishing Attacks: Trick users into revealing credentials or downloading malware.
Virus, Worms, and Spyware: Infecting IoT systems to steal data, disrupt services, or
propagate further infections.
Denial-of-Service (DoS) Attacks: Overwhelming IoT systems to disrupt functionality.
3. Network Attacks
Network-level threats exploit communication channels and protocols, involving:
Traffic Analysis: Monitoring network activity to infer sensitive information.
RFID Cloning: Duplicating RFID tags to gain unauthorized access.
RFID Spoofing: Imitating legitimate RFID communication to deceive systems.
Unauthorized Access: Gaining entry into networks by bypassing security measures.
Sinkhole Attacks: Redirecting network traffic through compromised nodes to disrupt
operations or gather sensitive data.
Man-in-the-Middle (MITM) Attacks: Intercepting communication between devices
to manipulate or steal data.
Routing Information Attacks: Altering network routing to misdirect traffic or disrupt
services.
4. Encryption Attacks
These attacks exploit weaknesses in cryptographic mechanisms that secure IoT
communications, including:
Side-Channel Attacks: Leveraging physical leakages, such as power usage, to infer
encryption keys.
Cryptanalysis Attacks: Breaking encryption algorithms to gain access to protected
data.
MITM Attacks: Exploiting encryption flaws to intercept and alter secure
communications.
The term “Internet of Things” (IoT) refers to a system of networked computing devices that
may work and communicate with one another without direct human intervention. It is one
of the most exciting areas of computing nowadays, with its applications in multiple sectors
like cities, homes, wearable equipment, critical infrastructure, hospitals, and
transportation
traditional security in the Internet of Things (IoT) involves established
methods such as cryptography, authentication, and authorization to
protect data and devices. However, these methods face significant
challenges due to the unique characteristics of IoT environments, such
as resource constraints and diverse device types. Traditional security
measures often struggle to adapt to the dynamic and heterogeneous
nature of IoT networks, necessitating the exploration of more
advanced and tailored security solutions. Below are key aspects of
traditional security in IoT and the challenges they face>
