Security and privacy controls within the cloud management landscape – Examining Security and Privacy in IoT

As more and more IoT devices are connected to the internet, cloud management has become an essential component of IoT networks. The cloud provides a scalable, flexible, and cost-effective solution for storing and processing the vast amounts of data generated by IoT devices. However, with the benefits of the cloud also come security and privacy concerns.

This section will discuss security and privacy controls that are necessary within the cloud management landscape to ensure the safe and effective operation of IoT networks. We will explore key security and privacy considerations in the cloud, including data encryption, identity and access management (IAM), network security, and compliance with regulatory requirements.

Types of attacks

IoT networks face numerous threats that come from various sources. Attackers could target physical devices, communication channels, or the cloud services that manage the devices. Each layer of the IoT network presents a different vulnerability, and attackers have different techniques for exploiting each layer.

Physical layer attacks

Physical attacks on IoT devices involve gaining access to the devices through direct manipulation. Attackers could physically connect to the device’s ports, such as USB or Ethernet ports, and install malicious firmware or software to take control of the device. Attackers could also use side-channel attacks to obtain sensitive information from the device’s hardware or firmware, such as encryption keys or other authentication data.

Data link layer attacks

Data link layer (DLL) attacks involve intercepting or manipulating communication between IoT devices and the network. Attackers could use techniques such as packet sniffing or man-in-the-middle (MitM) attacks to capture and modify data being transmitted between devices. Attackers could also use spoofing attacks to impersonate legitimate devices or gateways to gain access to the network.

Network layer attacks

Network layer attacks focus on disrupting the network infrastructure that connects IoT devices. Attackers could launch DDoS attacks to overload the network with traffic, causing it to become unresponsive. Attackers could also exploit vulnerabilities in the routing protocols used by IoT networks to redirect or manipulate data traffic.
