8/6/2024 Chip Terminologies in IoT Microprocessor Micro Controller Embedded System API (Application Programming Interface) Latency Telemetry AJ SoC (System on Chip) integrates all components of a computer or SoC = other electronic system. 1  8/6/2024 Examples on SoC Components of Soc Processor Memory Interface DSP I/O ports Almost all, every area, every device, every sensor, every software are connected to each other. The ability to access these devices through a smartphone or through a computer is called IoT. AJ 2  8/6/2024 What is IOT? The term Internet of Things generally refers to scenarios where network connectivity and computing capability extends to objects, sensors and everyday items not normally considered computers, allowing these devices to generate, exchange and consume data with minimal human intervention. IOT The IOT is widely used term for a set of technologies, systems and design principles associated with the emerging wave of internet connected things that are based on the physical environment. IOT is about the technology , the remote monitoring and control and also about where these technologies are applied. In many aspects it initially looks the same as M2M Communication – connecting sensors and other devices to information and communication technology systems via wired or wireless networks. What is M2M ? Machine to machine (M2M) is direct communication between devices using any communications channel, including wired and wireless. Machine to machine communication can include industrial instrumentation, enabling a sensor or meter to communicate the information it records (such as temperature, inventory level, etc.) to application software that can use it (for example, adjusting an industrial process based on temperature or placing orders to replenish inventory) 3  8/6/2024 DEFINITION OF M2M COMMUNICATION Machine-to-machine communication, or M2M, is exactly as it sounds: two machines “communicating,” or exchanging data, without human interfacing or interaction. This includes serial connection, powerline connection (PLC), or wireless communications in the industrial Internet of Things (IoT). Switching over to wireless has made M2M communication much easier and enabled more applications to be connected. M2M Communication M2M refers to those solutions that allows communication between devices of same type and specific applications. M2M solutions allows end-users to capture data about events from assets , such as temperature or inventory levels. M2M has been applied in many different scenarios, including the remote monitoring and control of enterprise assests,or to provide connectivity of remote machine-type device. Machine – To – Machine : device (water meter) which is monitored by means of sensor [in “uplink”] device (valve) which is instructed to actuate [in “downlink”] Machine – To – Machine : network which facilitates end-to-end connectivity between machines composed of radio, access network, gateway, core network, backend server Machine – To – Machine : device (computer) which extracts, processes (and displays) gathered information device (computer) which automatically controls and instructs other machines 4  8/6/2024 Difference Between IOT and M2M M2M IOT Abbreviation for machine to machine.

Example – Remote monitoring Example- Smart Cities 5  8/6/2024 key aspect to note between M2M and IoT is that the technology used for these solutions may be very similar they may even use the same base components but the manner in which the data is managed will be different. In an M2M solution, data remains within strict boundaries it is used solely for the purpose that it was originally developed for. With IoT, however, data may be used and reused for many different purposes, Reasons of IoT Data deluge : The explosion of the amount of data collected and exchanged is one of the major reason why IoT came in existence. Forecasts indicate that in the year 2015 more than 220 Exabytes of data are stored. So we need novel mechanisms to find, fetch, and transmit data. There is decrease in energy required to operate intelligent devices. The search will be for a zero level of entropy where the device or system will have to harvest its own energy. the devices are becoming increasingly smaller. Autonomic management: the devices/systems of future will have self-management, self-healing, and self-configuration capabilities AJ AJ 6  8/6/2024 Types of IoT Consumer IoT -home appliances, voice assistance, and light fixtures. Commercial IoT - Primarily used in the healthcare and transport industries. Eg: smart pacemakers and monitoring systems. Military Things (IoMT) - Primarily used for the application of IoT technologies in the military field. Eg: surveillance robots and human- wearable biometrics for combat. Industrial Internet of Things (IIoT) - Digital control systems, smart agriculture and industrial big data. Infrastructure IoT - connectivity in smart cities AJ AJ Threat vs. Opportunity If misunderstood and misconfigured, IoT poses risk to our data, privacy, and safety.

Do not trust blindly. Every device has its own defects. Only go for devices that offer security assurances. Ensure that the data you store is visible to only you. Enable private locks and security passwords. In case of open source data, do not leave the data unchecked. Never fail to use SSL layer and HTTPS protocol. Take care of your personal belongings where you have stored your IoT data. Example IMEI number There are several IoT wearable available. But choose only devices that are necessary to you, in your official or personal life. Never buy them just for the sake of experimenting. This could lead to trouble.

Internet of Things (IoT) devices were exploited by cybercriminals and turned into a rogue and malevolent army IoT’s are embedded with electronics, software, sensors and network connectivity so that they can connect to the internet. Modes of Attack Denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks If you flood a website with more traffic than it was built to handle, you'll overload the website's server and it'll be nigh-impossible for the website to serve up its content to visitors who are trying to access it. Man-in-the-middle (MitM) attack 20  8/6/2024 Phishing and spear phishing attacks Phishing attack is the practice of sending emails that appear to be from trusted sources with the goal of gaining personal information or influencing users to do something. It combines social engineering and technical trickery. It could involve an attachment to an email that loads malware onto your computer. It could also be a link to an illegitimate website that can trick you into downloading malware or handing over your personal information. Password attack Because passwords are the most commonly used mechanism to authenticate users to an information system, obtaining passwords is a common and effective attack approach Brute-force password guessing means using a random approach by trying different passwords and hoping that one work Some logic dictionary attack Malware attack – Can you define them Quick?
